“ZFS and Better File System (Btrfs) are two popular modern file systems. Both are designed with advanced storage features and offer snapshot capabilities, data integrity protection, and highly efficient storage management. However, ZFS has been the more reliable option for both personal and enterprise-level usage.”
I found this interesting as I did try a switch to Btrfs myself a while ago, but seem to remember I had speed issues as well as an inflated storage requirement. I liked the concept though. It is something I want to revisit in the future again, but I’ll probably give ZFS a more serious consideration then.
Right now I’m back on EXT4 with daily mirrored backups to two separate locations, and a selected cloud backup of critical data.
