'Backup' seems to contain data but does not show it

[pvswie]

I finally found some time to continue on implementing ZFS snapshotting and a backup.
Setup:

• VM with XigmaNAS (FreeBSD 13.2)
• 2 ZFS disks mounted as /mnt/pool/dataset and /mnt/pool-backup/dataset-backup

Command to backup pool to pool-backup:
/usr/local/bin/zfs-autobackup -v offsite1 pool-backup
which results in 'All operations completed successfully'

Looking at the target however no files are visible.
ls -al /mnt/pool-backup/dataset-backup
total 1
drwxrwxrwx 3 root wheel 2 Oct 5 08:50 .
drwxrwxrwx 3 root wheel 3 Oct 5 08:50 ..
dr-xr-xr-x+ 3 root wheel 3 Oct 5 08:50 .zfs

The .zfs folder also does not contain any files

What am I doing wrong?

you have to mount the datasets, with zfs mount -a

this will be fixed in the next version. see #112

Sorry I did not include that detail:

• I rebooted
• I ran zfs mount -a (as root) (before and after the reboot)
  Neither had any effect.

Any other ideas?

Well if you zfs list -r -t snapshot, and its there, you data should be there 100% as well.

Try explicitly mounting it with zfs mount.
