restic does not offer a backup restriction to specific filesystems, like IBM Spectrum Protect does.
One cannot automatically exclude NFS, fusefs, tmpfs etc filesystems.
This is especially a problem in case of a / fullback.
As a workaround I wrote “restic-backup” which scans /proc/mount and excludes all mount points which do not contain ext* xfs or btrfs filesystems:

Maybe there is another/better solution?
“–one-file-system” flag …?
I want a full system backup for ALL local file systens, not only / !
And –one-file-system also excludes btrfs subvolumes!
Indeed you have a bit special case. BTRFS or ZFS require a bit of manual treatment.
Thank you for sharing your script - can be useful for others in similar situation.
what does findmnt --fstab -o TARGET -n --submounts get you on a btrfs system?
Other than btrfs (which I don’t have) this seems to work fine on my machine
Does not list subvolumes:
root@fex:~# findmnt --fstab -o TARGET -n --submounts /
/
Also df does not list subvolumes:
root@fex:~# df -TH | grep btrfs
/dev/sdd1 btrfs 69G 16G 53G 23% /
/dev/sde1 btrfs 1.1T 91G 1.1T 9% /local
/dev/sdf1 btrfs 1.1T 361G 736G 33% /backup
/dev/loop0 btrfs 16T 1.2T 15T 8% /mnt/spool
/dev/mapper/nfsbackup btrfs 1.1T 116G 974G 11% /mnt/nfsbackup
But:
root@fex:~# restic backup -h | grep -- -x
-x, --one-file-system exclude other file systems, don't cross filesystem boundaries and subvolumes
Same is true for “find -xdev” and “du -x”
==> It is difficult to backup btrfs / with subvolumes, but exclude other filesystems
why did you add a “/” at the end? Can you try without it? Notice my example does not.
To restrict it to the / filesystem
root@fex:~# findmnt --fstab -o TARGET -n --submounts
/proc
/
none
/backup
/local
