Backups based on not-yet-reliable filesystems are, uh, less effective.
You're just grasping for straws at this point. Single-device Btrfs and
its core features like snapshotting and compression are very solid, it is
silly trying to "cast doubt" on those.
I'm not grasping for straws, but I do think I'm a lot more conservative
than you where backups are concerned!
depends also on the type of backup, normally you have more than once anyways
* microserver with NFS, dedicated to run a vmware backup-appliance
* that beast holding 31 days of anything is backuped
once per month on a external disk, there are two identical
external disks, one is always located off-house and both
are containing the *supsended* backup appliance inclduding memory
so, and the btrfs backup machine is located on the other side of the
town, does dauly backups and rnshshot for 7 days and is reachable via
ssh/sftp and key-auth - that one is mostly for "i have deleted a single
file or folder can you restore it"
why BTRFS?
because of the compression!
the other stuuf above is 1 time XFS and the external disks ext4
*that* is how a backup plan looks like because when you lose your
complete backup because one damaged filesystem you have no backup plan
at all (take it offeding if you want to do so...)
