VEEAM - How to do incremental backups on the backupserver even if the full backup is not in place anymore?

Hello,

I have a question regarding VEEAM Backup. We have many vSphere VMs which have terabytes of data. The typical backup strategy is to backup the VMs to disk and afterwards to tape as I know. We have enough space on the backup server to store the full backups but not for the incremental.

So I want to store the full backups on tape and afterwards delete it from the backup server. But VEEAM can not find the full backup anymore, so it starts a full backup instead of the incremenal. Is there a way to achieve what I want or are there any better strategies?

Any suggestions? Thank you in advance.

If you have only space for one full backup: with forever incremental or reverse incremental backup mode, you only need space for one full and the increments (although it is recommended to have space for one additional full in case you want to defragment the full backup, or for staging a restore from tape).

Starting with Windows Server 2016, you can also benefit from space saving with ReFS as filesystem and synthetic full backups in Veeam (will link blocks together instead of writing multiple copies of the same block)

Hello,

thank you for your fast response. The problem is that I have not enough space to store every full backup I need. So I wanted to create one full backup of every VM -> store it on tape -> delete them from the server to free disk space -> and only continue to make incremental backups. Is this possible?

So you also have not the space for the first full backup of all VM?
No, it is not possible to keep only incremental backups on disk - you need space for at least one full backup.
