This is usually the case, more confusion. Every file system has its |
35 |
strengths and its weaknesses. Here is some info BTRFS: |

This is what I suggest. Find out which file systems support the |
40 |
snapshot, since that is one thing that you have to have and a lot of |
41 |
file systems don't support it. Then research those to see which one |
42 |
matches your needs the closest. Keep in mind, none of them will be |
43 |
perfect. If you have large files, find out which one handles those |
44 |
best. If you have a lot of small files, which one handles those best. |
45 |
You will always have some trade offs tho. Example, XFS may be perfect |
46 |
but you may have to buy a really good UPS to work with your rig. It may |
47 |
be that EXT4 works best but still lacks something with regard to speed. |
48 |
Just another trade off. Just start with the must haves and work your |
49 |
way down the list until one file system is left. That will likely be |
50 |
your file system. |
51 |
|
52 |
I think the biggest thing, don't expect to find a file system that is |
53 |
perfect. None of them are really. |
