Hi,
I'm running Debian 10 with btrfs-progs=5.2.1.
Creating snapshots with snapper=0.8.2 works w/o errors.
root@ld5507:~# uname -r
5.0.18-1-pve
root@ld5508:~# btrfs fi show
Label: none uuid: 70997a0b-a36f-46cf-9ddc-b88d47eabc9e

Metadata, DUP: total=2.00GiB, used=465.84MiB
GlobalReserve, single: total=68.03MiB, used=0.00B
However, I run into an issue and need to restore various files.
I thought that I could simply take the files from a snapshot created before.
However, the files required don't exist in any snapshot!
Therefore I have created a new snapshot manually to verify if the files
will be included, but there's nothing.
These files are required:
root@ld5507:/usr/bin# ls -l /var/lib/ceph/osd/ceph-4/
insgesamt 56

-rw-r--r-- 1 ceph ceph 2 Jun 7 12:18 whoami
And there are not files in latest snapshot:
root@ld5507:/usr/bin# ls -l
/btrfs/@snapshots/158/snapshot/var/lib/ceph/osd/ceph-4/
insgesamt 0
Why is this?
THX
