[PROBLEM] How to recover Xbian BTRFS snapshot or a dir. from xbian_backup_home_01-01-23.img.gz?

[postcd]

Hello,

I need to recover one folder from the time around 1 week ago or older. Can i do it within Xbian BTRFS or on other computer i have xbian_backup_home_01-01-23.img.gz which i can extract, but do not know if/how to properly mount it while my other computer Linux Debian PC has no BTRFS.

Mounted extracted .img using Disks GUI tool in Debian (seeing loop0 in lsblk output). No available operation to see content.

losetup: /dev/shm/xbian_backup_home_01-01-23.img: Warning: file does not fit into a 512-byte sector; the end of the file will be ignored.

sudo mount /dev/loop{0,1} /mnt/xn
mount: /mnt/xn: wrong fs type, bad option, bad superblock on /dev/loop1, missing codepage or helper program, or other error.

List of BTRFS snapshots is here

The snapshot that looks like the one to restore seems to be:

Quote:ID 3790 gen 868586 top level 261 path home/@btrfs-auto-snap_monthly-2023-07-12-1045

Yet after like 30 minutes i have not found right command/s to restore it.
