I install Ubuntu Server 18.04 LTS as urbackup server with btrfs storage.
My task is backup vhdx on hyper-v server 2012r2 and 2016. I bought license for cbt client.
How can I setup forever incremental backup of vhdx with large size: one = 600 GB, other = 1850 GB.
Backup was made to offsite server with 50 mbit internet link.
I want make file backup with only incremental mode, because internet link very slow.
I create full backup of vhdx and make incremental 2-3 times.
And then delete all full and incremental backups exclude last incremental from web interface.
But backup integrity is fine. Why when full backup deleted, last incremental backup is enough??
