As i understand it, the --rotate argument acts on an entire backup repo irrespective of what VMs have been chosen to be backed up correct?
For example, if i have 2 hosts backing up to the same repo (not using --subfolder) and the first host uses the --rotate argument while the second does not, i should expect the old backups from the second host to be purged when the first backup command rotates correct? Just trying to get an understanding as I may choose to backup some VMs at a less frequent interval due to size etc.
Is there any thought towards perhaps defining the rotation to be respective to the VM level (ie. 7 revisions of each VM, but VM1 backs up weekly, while VM 2 backs up nightly, etc.)
It is very simple, --rotate deletes anything older than the number of backups to keep in the repository you are working on, regardless of where you run it from.
