This. I use it on a tiny backup server with only 1 GB of RAM and a 4 TB HDD pool, it's fine. Only one machine backs up to that server at a time, and they do that at network speed (which is admittedly only 100 Mb/s, but it should go somewhat higher if it had faster network). Restore also runs ok.

Thanks for this. I initially went with xfs back when there were license and quality concerns with zfs on Linux before btrfs was a thing, and moved to btrfs after btrfs was created and matured a bit.

These days, I think I would be happier with zfs and one RAID-Z pool across all of the disks instead of individual btrfs partitions or btrfs on RAID 5.
