What I did was creating a snapshot with incus, then using btrfs to send it somewhere else:
btrfs send /var/lib/incus/storage-pools/incus/virtual-machines-snapshots/MikroTik/snap|btrfs receive /mnt/MikroTik
incus snapshot delete MikroTik snap
btrfs send /mnt/MikroTik/snap|btrfs receive /var/lib/incus/storage-pools/incus/virtual-machines-snapshots/MikroTik
But it doesn’t show up with incus snapshot list Mikrotik
Do I have to add something to the Database?
