Every file system has its strengths and its weaknesses. Here is some info BTRFS: https://btrfs.wiki.kernel.org/index.php/Using_Btrfs_with_Multiple_Devices#Current_Status This is what I suggest. Find out which file systems support the snapshot, since that is one thing that you have to have and a lot of file systems don't support it. Then research those to see which one matches your needs the closest. Keep in mind, none of them will be perfect. If you have large files, find out which one handles those best. If you have a lot of small files, which one handles those best. You will always have some trade offs tho. Example, XFS may be perfect but you may have to buy a really good UPS to work with your rig. It may be that EXT4 works best but still lacks something with regard to speed. Just another trade off. Just start with the must haves and work your way down the list until one file system is left. That will likely be your file system. I think the biggest thing, don't expect to find a file system that is perfect. None of them are really. Dale :-) :-)
