I am currently running Veeam Backup & Replication 5.02. Love the product, but am constantly fighting disk space issues. We run Synthetic Fulls to run on the weekend. As an example, if I have a Full job run for a set of Windows 2003 server VMs, on Friday, and Incrementals that run Monday-Friday the following week, with a new Synthetic Full to be created that night. If the number of Restore points to keep on Disk were set to 1, when that new Synthetic Full got created, would all previous incrementals and the previous Full VBK file get deleted by Veeam? Ideally, we would like to keep one Full VBK and 4 incremental VIB files for any backup job on the disk. We run Full backups to tape on Sunday, and back up the incremental VIBs to tape each night as well. Those tapes then go offsite, and could be recalled if we ever had to go back longer than 1 week to restore a VM or guest files from a VM backup. Our corporate retention policy is 6 weeks for all backups. So, our thought is to have 1 week of VM backups on the disk, and the rest on tape if we need to recall it.
Right now the Restore Points to keep on disk is set to 5, but I think that leaves open the scenario to have more than one VBK file on the disk at any one time, which we do not want. That is why I was thinking of changing that number to 1.
