I’m working on making a new urbackup server. We are using a mixture of Image based backups, and file based backups as of current against BTRFS. However, we want to move to image based backups for everything. The problem of course becomes space.
So, my first question is can ZFS deduplicate two identical files in two different machine images? Do I need special settings to make this happen, and what are they?
Secondly, is there any statistics on the space savings between ZFS and BTRFS for image and file based backups?
Finally, any suggestions or warnings in the utilization of ZFS with urbackup?
Thank you for your time.
