<p><b>LINUX INNARDS:</b></p>
<p><b>Compression</b></p>
<ul>
<li style="font-weight: 400;" aria-level="1"><span style="font-weight: 400;">Joe</span>
<ul>
<li style="font-weight: 400;" aria-level="2"><span style="font-weight: 400;">I tried to use the built in tool to compress my home drive but kept running into permissions problems even as root. </span></li>
<li style="font-weight: 400;" aria-level="2"><span style="font-weight: 400;">So I used tar.gz in order to test the compression on my Downloads folder which started out as 58.8 gb and ended up at like 55 gb so not much savings in space</span></li>
</ul>
</li>
<li style="font-weight: 400;" aria-level="1"><span style="font-weight: 400;">TonyH  </span>
<ul>
<li style="font-weight: 400;" aria-level="2"><span style="font-weight: 400;">I ran .tar.gz on my desktop folder which was 40.3Gb I backed this folder up to one of my external 4Tb drives I use for backup and storage and after completion the new folder was 33.3Gb so a saving of 7Gb just on this one folder, so if space was an issue this would be a good way to backup folders and save some space. Just for comparison, 7Gb is larger than the 6Gb HDD I had in my first Windows PC back in late 1998 and that was a decent amount of storage for the time, lol.  </span></li>
</ul>
</li>
<li style="font-weight: 400;" aria-level="1"><span style="font-weight: 400;">Moss</span>
<ul>
<li style="font-weight: 400;" aria-level="2"><span style="font-weight: 400;">I keep most of my files most people keep in Home on an external drive, so there wasn’t much in my Home folder to compress. In fact, my Home folder was only 1.5 Gb; running compression, the resulting files were each 1.7 Gb. I ran both .tar.gz and .tar.7z for comparison with no difference. Maybe I should check compression on my external, but I’m not sure I have room anywhere for a file which would hold all that. /dev/sdb is a 512 Gb drive with only 145 Gb free&#8230;</span></li>
</ul>
</li>
<li style="font-weight: 400;" aria-level="1"><span style="font-weight: 400;">Josh</span>
<ul>
<li style="font-weight: 400;" aria-level="2"><span style="font-weight: 400;">I mainly tested my compression on my .img backups of my internal nvme drive with about 506 GB of data on it using dd and partclone to image the disk and pigz to compress. I tried both 7z and gzip but for this task both of them take way too long at over 5 hours estimated time. </span></li>
<li style="font-weight: 400;" aria-level="2"><span style="font-weight: 400;">Rescuezilla won the speed of compression coming in at 55 minutes. The compressed size was tied with Partclone+pigz at 383GB. I am unsure of the exact command it uses.</span></li>
<li style="font-weight: 400;" aria-level="2"><span style="font-weight: 400;">Partclone + pigz came in second at 57 minutes. The compressed size as I have stated earlier is exactly the same as Rescuzilla at 383GB. The command I used to achieve this was.</span>
<ul>
<li style="font-weight: 400;" aria-level="3"><span style="font-weight: 400;">partclone.ntfs -c -s /dev/nvme0n1p3 | pigz -9 &gt; /mnt/backup/backup.img.gz</span></li>
</ul>
</li>
<li style="font-weight: 400;" aria-level="2"><span style="font-weight: 400;">dd + pigz came in 3rd at 1H 38M. The compressed size was a little larger than the other two at 387GB and the command I used to achieve all this was.</span>
<ul>
<li style="font-weight: 400;" aria-level="3"><span style="font-weight: 400;">dd if=/dev/nvme0n1p3 | pv | pigz -9 &gt; /mnt/backup/backup.img.gz</span></li>
</ul>
</li>
<li style="font-weight: 400;" aria-level="2"><span style="font-weight: 400;">As I said before 7z took too long. I am not sure why this is but it is supposed to be multithreaded but when looking at htop only one thread was in use. In a later test of compressing a folder I had it actually did use all my cores to compress and the time it took was not that long. I cannot use that to compare against my other findings because it was not the same file I was compressing but I think it would perform close to the others.</span></li>
</ul>
</li>
<li style="font-weight: 400;" aria-level="1"><span style="font-weight: 400;">Leo</span>
<ul>
<li style="font-weight: 400;" aria-level="2"><span style="font-weight: 400;">For long compressions, install and use progress to monitor that state of tar.</span>
<ul>
<li style="font-weight: 400;" aria-level="3"><span style="font-weight: 400;">sudo apt install progress</span></li>
<li style="font-weight: 400;" aria-level="3"><span style="font-weight: 400;">progress -m</span></li>
<li style="font-weight: 400;" aria-level="3"><span style="font-weight: 400;">It won’t tell you the status of the whole compression process, but will tell you the status of each file, at least letting you know that it’s working and will exit automatically when done.</span></li>
</ul>
</li>
<li style="font-weight: 400;" aria-level="2"><span style="font-weight: 400;">I currently have a 1.2GB home folder on this machine. Mostly downloaded files like a Lineage image, nyquist plugins for audacity, and a little more than half of the size is pictures.</span>
<ul>
<li style="font-weight: 400;" aria-level="3"><span style="font-weight: 400;">xz</span>
<ul>
<li style="font-weight: 400;" aria-level="4"><span style="font-weight: 400;">tar -cJf /media/leo/Ventoy/Backup/home.tar.xz ~/*</span></li>
<li style="font-weight: 400;" aria-level="4"><span style="font-weight: 400;">Done in about 5 minutes</span></li>
<li style="font-weight: 400;" aria-level="4"><span style="font-weight: 400;">2nd Best compression: 1,128,815,932 bytes</span></li>

</ul>
</li>
</ul>
</li>
<li style="font-weight: 400;" aria-level="2"><span style="font-weight: 400;">All the algorithms seemed to have saved me about 10% on the backup.</span></li>
<li style="font-weight: 400;" aria-level="2"><span style="font-weight: 400;">Josh and I have been playing around with pigz, which is a rewrite of gzip to include multi-core CPU support. To do the same backup as above:</span>
<ul>
<li style="font-weight: 400;" aria-level="3"><span style="font-weight: 400;">sudo apt install pigz</span></li>
<li style="font-weight: 400;" aria-level="3"><span style="font-weight: 400;">tar &#8211;use-compress-program=&#8221;pigz &#8211;best &#8211;recursive&#8221; -cf /media/leo/Ventoy/Backup/home.tar.gz ~/*</span></li>
<li style="font-weight: 400;" aria-level="3"><span style="font-weight: 400;">Done in about 30 seconds</span></li>
<li style="font-weight: 400;" aria-level="3"><span style="font-weight: 400;">Ever so slightly worse compression than gz? Approximately 1MB diff.</span>
<ul>
<li style="font-weight: 400;" aria-level="4"><span style="font-weight: 400;">1,144,479,482 bytes</span></li>

<p><b>LINUX INNARDS:</b></p>
<p><b>Compression</b></p>
<ul>
<li style="font-weight: 400;" aria-level="1"><span style="font-weight: 400;">Joe</span>
<ul>
<li style="font-weight: 400;" aria-level="2"><span style="font-weight: 400;">I tried to use the built in tool to compress my home drive but kept running into permissions problems even as root. </span></li>
<li style="font-weight: 400;" aria-level="2"><span style="font-weight: 400;">So I used tar.gz in order to test the compression on my Downloads folder which started out as 58.8 gb and ended up at like 55 gb so not much savings in space</span></li>
</ul>
</li>
<li style="font-weight: 400;" aria-level="1"><span style="font-weight: 400;">TonyH  </span>
<ul>
<li style="font-weight: 400;" aria-level="2"><span style="font-weight: 400;">I ran .tar.gz on my desktop folder which was 40.3Gb I backed this folder up to one of my external 4Tb drives I use for backup and storage and after completion the new folder was 33.3Gb so a saving of 7Gb just on this one folder, so if space was an issue this would be a good way to backup folders and save some space. Just for comparison, 7Gb is larger than the 6Gb HDD I had in my first Windows PC back in late 1998 and that was a decent amount of storage for the time, lol.  </span></li>
</ul>
</li>
<li style="font-weight: 400;" aria-level="1"><span style="font-weight: 400;">Moss</span>
<ul>
<li style="font-weight: 400;" aria-level="2"><span style="font-weight: 400;">I keep most of my files most people keep in Home on an external drive, so there wasn’t much in my Home folder to compress. In fact, my Home folder was only 1.5 Gb; running compression, the resulting files were each 1.7 Gb. I ran both .tar.gz and .tar.7z for comparison with no difference. Maybe I should check compression on my external, but I’m not sure I have room anywhere for a file which would hold all that. /dev/sdb is a 512 Gb drive with only 145 Gb free&#8230;</span></li>
</ul>
</li>
<li style="font-weight: 400;" aria-level="1"><span style="font-weight: 400;">Josh</span>
<ul>
<li style="font-weight: 400;" aria-level="2"><span style="font-weight: 400;">I mainly tested my compression on my .img backups of my internal nvme drive with about 506 GB of data on it using dd and partclone to image the disk and pigz to compress. I tried both 7z and gzip but for this task both of them take way too long at over 5 hours estimated time. </span></li>
<li style="font-weight: 400;" aria-level="2"><span style="font-weight: 400;">Rescuezilla won the speed of compression coming in at 55 minutes. The compressed size was tied with Partclone+pigz at 383GB. I am unsure of the exact command it uses.</span></li>
<li style="font-weight: 400;" aria-level="2"><span style="font-weight: 400;">Partclone + pigz came in second at 57 minutes. The compressed size as I have stated earlier is exactly the same as Rescuzilla at 383GB. The command I used to achieve this was.</span>
<ul>
<li style="font-weight: 400;" aria-level="3"><span style="font-weight: 400;">partclone.ntfs -c -s /dev/nvme0n1p3 | pigz -9 &gt; /mnt/backup/backup.img.gz</span></li>
</ul>
</li>
<li style="font-weight: 400;" aria-level="2"><span style="font-weight: 400;">dd + pigz came in 3rd at 1H 38M. The compressed size was a little larger than the other two at 387GB and the command I used to achieve all this was.</span>
<ul>
<li style="font-weight: 400;" aria-level="3"><span style="font-weight: 400;">dd if=/dev/nvme0n1p3 | pv | pigz -9 &gt; /mnt/backup/backup.img.gz</span></li>
</ul>
</li>
<li style="font-weight: 400;" aria-level="2"><span style="font-weight: 400;">As I said before 7z took too long. I am not sure why this is but it is supposed to be multithreaded but when looking at htop only one thread was in use. In a later test of compressing a folder I had it actually did use all my cores to compress and the time it took was not that long. I cannot use that to compare against my other findings because it was not the same file I was compressing but I think it would perform close to the others.</span></li>
</ul>
</li>
<li style="font-weight: 400;" aria-level="1"><span style="font-weight: 400;">Leo</span>
<ul>
<li style="font-weight: 400;" aria-level="2"><span style="font-weight: 400;">For long compressions, install and use progress to monitor that state of tar.</span>
<ul>
<li style="font-weight: 400;" aria-level="3"><span style="font-weight: 400;">sudo apt install progress</span></li>
<li style="font-weight: 400;" aria-level="3"><span style="font-weight: 400;">progress -m</span></li>
<li style="font-weight: 400;" aria-level="3"><span style="font-weight: 400;">It won’t tell you the status of the whole compression process, but will tell you the status of each file, at least letting you know that it’s working and will exit automatically when done.</span></li>
</ul>
</li>
<li style="font-weight: 400;" aria-level="2"><span style="font-weight: 400;">I currently have a 1.2GB home folder on this machine. Mostly downloaded files like a Lineage image, nyquist plugins for audacity, and a little more than half of the size is pictures.</span>

<li style="font-weight: 400;" aria-level="3"><span style="font-weight: 400;">xz</span>
<ul>
<li style="font-weight: 400;" aria-level="4"><span style="font-weight: 400;">tar -cJf /media/leo/Ventoy/Backup/home.tar.xz ~/*</span></li>
<li style="font-weight: 400;" aria-level="4"><span style="font-weight: 400;">Done in about 5 minutes</span></li>

</ul>
</li>
</ul>
</li>
<li style="font-weight: 400;" aria-level="2"><span style="font-weight: 400;">All the algorithms seemed to have saved me about 10% on the backup.</span></li>
<li style="font-weight: 400;" aria-level="2"><span style="font-weight: 400;">Josh and I have been playing around with pigz, which is a rewrite of gzip to include multi-core CPU support. To do the same backup as above:</span>
<ul>
<li style="font-weight: 400;" aria-level="3"><span style="font-weight: 400;">sudo apt install pigz</span></li>
<li style="font-weight: 400;" aria-level="3"><span style="font-weight: 400;">tar &#8211;use-compress-program=&#8221;pigz &#8211;best &#8211;recursive&#8221; -cf /media/leo/Ventoy/Backup/home.tar.gz ~/*</span></li>
<li style="font-weight: 400;" aria-level="3"><span style="font-weight: 400;">Done in about 30 seconds</span></li>
<li style="font-weight: 400;" aria-level="3"><span style="font-weight: 400;">Ever so slightly worse compression than gz? Approximately 1MB diff.</span>
<ul>
<li style="font-weight: 400;" aria-level="4"><span style="font-weight: 400;">1,144,479,482 bytes</span></li>

<p><b>LINUX INNARDS:</b><span style="font-weight: 400;">&nbsp;</span></p>
<p>Joshua Hawk</p>
<p><b>When did you first learn about Linux?</b></p>
<p><b>When did you start using it as much as you do?</b></p>
<p><b>Btrfs &#8211; No Partitions Needed, with Joshua Hawk&nbsp;</b></p>
<ul>
<li>Features</li>
</ul>
<ol>
<li style="list-style-type: none;">
<ol>
<li style="font-weight: 400;"><span style="font-weight: 400;">Copy on Write (CoW)</span>
<ol>
<li style="font-weight: 400;"><span style="font-weight: 400;">Creates new files when storing data instead of overwriting current data.</span></li>
<li style="font-weight: 400;"><span style="font-weight: 400;">Necessary for snapshots</span></li>
</ol>
</li>
<li style="font-weight: 400;"><span style="font-weight: 400;">Subvolumes</span>
<ol>
<li style="font-weight: 400;"><span style="font-weight: 400;">Like a partition but has access to the entire space of the btrfs formatted disk.</span></li>
<li style="font-weight: 400;"><span style="font-weight: 400;">Also necessary for snapshots</span></li>
<li style="font-weight: 400;"><span style="font-weight: 400;">Can be interacted with either like a directory on a filesystem or like a separately mounted filesystem.</span></li>
<li style="font-weight: 400;"><span style="font-weight: 400;">Some subvolume commands</span>
<ol>
<li style="font-weight: 400;"><span style="font-weight: 400;">&nbsp;subvolume create [destination] &lt;name of subvolume&gt;</span></li>
<li style="font-weight: 400;"><span style="font-weight: 400;">subvolume delete [option] &lt;subvolume name&gt; [&lt;subvolume inside subvolume&gt;]&nbsp;</span></li>
<li style="font-weight: 400;"><span style="font-weight: 400;">subvolume list [options] [&#8211;sort=rootid,gen,ogen,path] &lt;path&gt;</span></li>
</ol>
</li>
</ol>
</li>
<li style="font-weight: 400;"><span style="font-weight: 400;">Snapshots</span>
<ol>
<li style="font-weight: 400;"><span style="font-weight: 400;">NOT BACKUPS! They are akin to Windows system restore points but far far superior.&nbsp;</span></li>
<li style="font-weight: 400;"><span style="font-weight: 400;">Can be automated using snapper or timeshift.</span></li>
<li style="font-weight: 400;"><span style="font-weight: 400;">Is a subvolume itself that points to data and metadata in its parent subvolume.</span></li>
<li style="font-weight: 400;"><span style="font-weight: 400;">NOT BACKUPS!&nbsp;</span></li>
</ol>
</li>
<li style="font-weight: 400;"><span style="font-weight: 400;">File System Compression (ZLIB, LZO, ZSTD)</span>
<ol>
<li style="font-weight: 400;"><span style="font-weight: 400;">Saves space sometimes up to 20%-30%</span></li>
<li style="font-weight: 400;"><span style="font-weight: 400;">Increases life of SSD’s due to significantly less writes</span></li>
<li style="font-weight: 400;"><span style="font-weight: 400;">ZSTD is flexible and configurable to your needs.</span></li>
<li style="font-weight: 400;"><span style="font-weight: 400;">Mounting a subvolume with the compression option won’t compress files currently on subvolume.</span></li>
<li style="font-weight: 400;"><span style="font-weight: 400;">To compress files already contained in a subvolume you must use the Defrag command with the -r option</span></li>
</ol>
</li>
<li style="font-weight: 400;"><span style="font-weight: 400;">Checksumming</span>
<ol>
<li style="font-weight: 400;"><span style="font-weight: 400;">Not Enabled on SSD’s by default due to the fact that ssd’s tend to just fail rather than die slowly. If you want this feature with ssd’s it is recommended to use 2 ssd’s in a RAID 1 Configuration.</span></li>
<li style="font-weight: 400;"><span style="font-weight: 400;">Enabled by default on HDD’s and when used with RAID 1 will checksum and self heal files that are corrupt.&nbsp;</span></li>
</ol>
</li>
<li style="font-weight: 400;"><span style="font-weight: 400;">SSD Awareness</span>
<ol>
<li style="font-weight: 400;"><span style="font-weight: 400;">Disables file duplication to reduce writes</span></li>
<li style="font-weight: 400;"><span style="font-weight: 400;">TRIM/Discard to report free blocks for reuse</span></li>
<li style="font-weight: 400;"><span style="font-weight: 400;">Sends writes in clusters resulting in larger write operations and faster throughput.&nbsp;</span></li>
</ol>
</li>
<li style="font-weight: 400;"><span style="font-weight: 400;">Send/Receive of subvolume changes</span>
<ol>
<li style="font-weight: 400;"><span style="font-weight: 400;">Can send and receive subvolumes and changes to those subvolumes over the network for backup operations.</span></li>
</ol>
</li>
<li style="font-weight: 400;"><span style="font-weight: 400;">RAID Support</span>
<ol>
<li style="font-weight: 400;"><span style="font-weight: 400;">RAID 0, 1, 5, 6, 10 support</span></li>
<li style="font-weight: 400;"><span style="font-weight: 400;">RAID 5 and 6 are experimental and are NOT recommended!</span></li>
<li style="font-weight: 400;"><span style="font-weight: 400;">RAID 0, 1, and 10 are production ready</span></li>
<li style="font-weight: 400;"><span style="font-weight: 400;">Can add and remove storage to RAID on the fly</span></li>
</ol>
</li>
</ol>
</li>
</ol>
<ol>
<li style="font-weight: 400;"><span style="font-weight: 400;">When to use btrfs</span>
<ol>
<li style="font-weight: 400;"><span style="font-weight: 400;">Root Filesystem</span></li>
<li style="font-weight: 400;"><span style="font-weight: 400;">Redundant data storage (NAS)</span></li>
<li style="font-weight: 400;"><span style="font-weight: 400;">Laptops with SSDs</span></li>
<li style="font-weight: 400;"><span style="font-weight: 400;">Btrfs works for MOST filesystem cases</span></li>
</ol>
</li>
</ol>
<ol>
<li style="font-weight: 400;"><span style="font-weight: 400;">When not to use btrfs</span>
<ol>
<li style="font-weight: 400;"><span style="font-weight: 400;">Anything that does not need redundant data storage (video game data storage for example excluding game save data)</span></li>
<li style="font-weight: 400;"><span style="font-weight: 400;">Databases due to the slow nature of CoW.</span></li>
</ol>
</li>
</ol>
<ol>
<li style="font-weight: 400;"><span style="font-weight: 400;">Issues with btrfs</span>
<ol>
<li style="font-weight: 400;"><span style="font-weight: 400;">Will not mount a filesystem if errors are detected on disk. This can be corrected by using the scrub command 99% of the time.</span></li>
<li style="font-weight: 400;"><span style="font-weight: 400;">If connection is lost or computer/server loses power during some btrfs operations, may result in data corruption or file system issues.</span></li>
<li style="font-weight: 400;"><span style="font-weight: 400;">If snapshots are not being controlled by a script or a limit is not set the disk drive may fill up and cause issues. Can be corrected by deleting some snapshots.</span></li>
<li style="font-weight: 400;"><span style="font-weight: 400;">As stated before RAID 5/6&nbsp; is experimental and has major issues.&nbsp;</span></li>

<p><b>LINUX INNARDS:</b><span style="font-weight: 400;">&nbsp;</span></p>
<p>Joshua Hawk</p>
<p><b>When did you first learn about Linux?</b></p>
<p><b>When did you start using it as much as you do?</b></p>
<p><b>Btrfs &#8211; No Partitions Needed, with Joshua Hawk&nbsp;</b></p>
<ul>
<li>Features</li>
</ul>
<ol>
<li style="list-style-type: none;">
<ol>
<li style="font-weight: 400;"><span style="font-weight: 400;">Copy on Write (CoW)</span>
<ol>
<li style="font-weight: 400;"><span style="font-weight: 400;">Creates new files when storing data instead of overwriting current data.</span></li>
<li style="font-weight: 400;"><span style="font-weight: 400;">Necessary for snapshots</span></li>
</ol>
</li>
<li style="font-weight: 400;"><span style="font-weight: 400;">Subvolumes</span>
<ol>
<li style="font-weight: 400;"><span style="font-weight: 400;">Like a partition but has access to the entire space of the btrfs formatted disk.</span></li>
<li style="font-weight: 400;"><span style="font-weight: 400;">Also necessary for snapshots</span></li>
<li style="font-weight: 400;"><span style="font-weight: 400;">Can be interacted with either like a directory on a filesystem or like a separately mounted filesystem.</span></li>
<li style="font-weight: 400;"><span style="font-weight: 400;">Some subvolume commands</span>
<ol>
<li style="font-weight: 400;"><span style="font-weight: 400;">&nbsp;subvolume create [destination] &lt;name of subvolume&gt;</span></li>
<li style="font-weight: 400;"><span style="font-weight: 400;">subvolume delete [option] &lt;subvolume name&gt; [&lt;subvolume inside subvolume&gt;]&nbsp;</span></li>
<li style="font-weight: 400;"><span style="font-weight: 400;">subvolume list [options] [&#8211;sort=rootid,gen,ogen,path] &lt;path&gt;</span></li>
</ol>
</li>
</ol>
</li>
<li style="font-weight: 400;"><span style="font-weight: 400;">Snapshots</span>
<ol>
<li style="font-weight: 400;"><span style="font-weight: 400;">NOT BACKUPS! They are akin to Windows system restore points but far far superior.&nbsp;</span></li>
<li style="font-weight: 400;"><span style="font-weight: 400;">Can be automated using snapper or timeshift.</span></li>
<li style="font-weight: 400;"><span style="font-weight: 400;">Is a subvolume itself that points to data and metadata in its parent subvolume.</span></li>
<li style="font-weight: 400;"><span style="font-weight: 400;">NOT BACKUPS!&nbsp;</span></li>
</ol>
</li>
<li style="font-weight: 400;"><span style="font-weight: 400;">File System Compression (ZLIB, LZO, ZSTD)</span>
<ol>
<li style="font-weight: 400;"><span style="font-weight: 400;">Saves space sometimes up to 20%-30%</span></li>
<li style="font-weight: 400;"><span style="font-weight: 400;">Increases life of SSD’s due to significantly less writes</span></li>
<li style="font-weight: 400;"><span style="font-weight: 400;">ZSTD is flexible and configurable to your needs.</span></li>
<li style="font-weight: 400;"><span style="font-weight: 400;">Mounting a subvolume with the compression option won’t compress files currently on subvolume.</span></li>
<li style="font-weight: 400;"><span style="font-weight: 400;">To compress files already contained in a subvolume you must use the Defrag command with the -r option</span></li>
</ol>
</li>
<li style="font-weight: 400;"><span style="font-weight: 400;">Checksumming</span>
<ol>
<li style="font-weight: 400;"><span style="font-weight: 400;">Not Enabled on SSD’s by default due to the fact that ssd’s tend to just fail rather than die slowly. If you want this feature with ssd’s it is recommended to use 2 ssd’s in a RAID 1 Configuration.</span></li>
<li style="font-weight: 400;"><span style="font-weight: 400;">Enabled by default on HDD’s and when used with RAID 1 will checksum and self heal files that are corrupt.&nbsp;</span></li>
</ol>
</li>
<li style="font-weight: 400;"><span style="font-weight: 400;">SSD Awareness</span>
<ol>
<li style="font-weight: 400;"><span style="font-weight: 400;">Disables file duplication to reduce writes</span></li>
<li style="font-weight: 400;"><span style="font-weight: 400;">TRIM/Discard to report free blocks for reuse</span></li>
<li style="font-weight: 400;"><span style="font-weight: 400;">Sends writes in clusters resulting in larger write operations and faster throughput.&nbsp;</span></li>
</ol>
</li>
<li style="font-weight: 400;"><span style="font-weight: 400;">Send/Receive of subvolume changes</span>
<ol>
<li style="font-weight: 400;"><span style="font-weight: 400;">Can send and receive subvolumes and changes to those subvolumes over the network for backup operations.</span></li>
</ol>
</li>
<li style="font-weight: 400;"><span style="font-weight: 400;">RAID Support</span>
<ol>
<li style="font-weight: 400;"><span style="font-weight: 400;">RAID 0, 1, 5, 6, 10 support</span></li>
<li style="font-weight: 400;"><span style="font-weight: 400;">RAID 5 and 6 are experimental and are NOT recommended!</span></li>
<li style="font-weight: 400;"><span style="font-weight: 400;">RAID 0, 1, and 10 are production ready</span></li>
<li style="font-weight: 400;"><span style="font-weight: 400;">Can add and remove storage to RAID on the fly</span></li>
</ol>
</li>
</ol>
</li>
</ol>
<ol>
<li style="font-weight: 400;"><span style="font-weight: 400;">When to use btrfs</span>
<ol>
<li style="font-weight: 400;"><span style="font-weight: 400;">Root Filesystem</span></li>
<li style="font-weight: 400;"><span style="font-weight: 400;">Redundant data storage (NAS)</span></li>
<li style="font-weight: 400;"><span style="font-weight: 400;">Laptops with SSDs</span></li>
<li style="font-weight: 400;"><span style="font-weight: 400;">Btrfs works for MOST filesystem cases</span></li>
</ol>
</li>
</ol>
<ol>
<li style="font-weight: 400;"><span style="font-weight: 400;">When not to use btrfs</span>
<ol>
<li style="font-weight: 400;"><span style="font-weight: 400;">Anything that does not need redundant data storage (video game data storage for example excluding game save data)</span></li>
<li style="font-weight: 400;"><span style="font-weight: 400;">Databases due to the slow nature of CoW.</span></li>
</ol>
</li>
</ol>
<ol>
<li style="font-weight: 400;"><span style="font-weight: 400;">Issues with btrfs</span>
<ol>
<li style="font-weight: 400;"><span style="font-weight: 400;">Will not mount a filesystem if errors are detected on disk. This can be corrected by using the scrub command 99% of the time.</span></li>
<li style="font-weight: 400;"><span style="font-weight: 400;">If connection is lost or computer/server loses power during some btrfs operations, may result in data corruption or file system issues.</span></li>
<li style="font-weight: 400;"><span style="font-weight: 400;">If snapshots are not being controlled by a script or a limit is not set the disk drive may fill up and cause issues. Can be corrected by deleting some snapshots.</span></li>
<li style="font-weight: 400;"><span style="font-weight: 400;">As stated before RAID 5/6&nbsp; is experimental and has major issues.&nbsp;</span></li>
