ZFS COW questions

Server
1

Hi, I’ve just configured ZFS Copy-on-write for files and images.

For the most part it’s working, but i have some questions/doubts and a weird issue:

  1. Is it not possible to mount a ZFS COW image backup from the web gui? Any other way to mount them? (i am using debian)

  2. Can i completely disable full image and file backups and keep only incrementals enabled?

  3. When i run “urbackupsrv remove-unknown” it doesn’t find the ZFS COW image backups on the disk (it says access denied) and deletes them both from database and disk, even though they do exist. How can i fix this?

Thank you in advance!
