I’m currently testing out urbackup and struggle a bit to enable deduplication.
As a test, I did 3 images of a Windows laptop back to back. The backed up drive got 30gb of data, each backup (cVHD) is 15gb in size. I expected to see actual drive usage of <20gb for all three backups, since no meaningful amount of data changed since the last backup.
However, it uses the “full” 45gb as seen below.
UrBackup server is running on a Debian VM and backs-up to a ZFS accessed via SMB (going to switch to NFS). I know that ZFS supports block-level-deduplication, but since the same Pool gets used as NAS, I don’t want to enable it there.
Quick side question, how do I browse an image in the web interface?
I’ve found this blog post, but it doesn’t show the “Mount Image” button for me.
