This works fine (mostly - see comment bellow *cough* gostev please fix *cough*), but not the way I wanted it to.
I was looking to keeping a copy of 3 restore points on each disk from the 3 restore points of the evening daily backup. However, I don't see any way to do that currently in Veeam. It will keep 3 restore points on the disk rather than copy 3 restore points (just copies the latest). Since the rotation occurs daily for a disk to get 2nd restore point it has to wait a week to be connected (or longer for the Sunday "weekly disks).
The use case for this if that there is something wrong with a particular backup (e.g. the snapshot contains a corrupt copy that was not there in the previous one) there would still be 2 previous snapshots to rely on.
Tl;DR: So is there a way to instruct Veeam to copy more than 1 restore point in a backup copy cycle? If not I am requesting this feature.
I've configured the backup copy in periodic mode that runs each cycle at 12:01 each day. If I do immediate there is not enough time for daily the backups to copy over until 8:00 when the disk gets swapped. Daily backups occur at 19:00 and can take up to 2:00 to finish them all.
In regards to the annoying thing about periodic backups (support case 04780019) - when the new backup copy cycle runs at 12:01 it first FAILS the backup copy job and then restarts it. The backup eventually copies over, but until then Veeam shows the last status as FAILED, Veeam ONE goes red, and I and the CLIENT get emails about it. What's the official solution? Known bug - ignore the emails
