Whats happens if an incremental backup gets damaged?

[isd17]

The first backup ist a full backup. All following backups are incremental backups.

What happens if I have 120 incremental backups, and backup number 80 is corrupted. Can I restore data from backup numer 79 and before?
What can I do to prevent damaged backups?

And another question:
Is it possible to do a local backup alternately on two hard drives. For example: Can i switch harddrives every week?

Hi @isd17 ,

If you're using local repository, there's a backup database (.adb) under the hood and all backup data is stored there. It's not the collection of backup files (like in VBR) that may get corrupted. What potentially can happen is a database corruption, but there're certain methods to fix this and in most cases it allows to avoid any data loss. As a second layer of protection, you can leverage VBR backups of the VBO server to keep a secondary copy of your VBO repositories.

Thanks!

Thanks for the reply. What do you mean by:
"As a second layer of protection, you can leverage VBR backups of the VBO server to keep a secondary copy of your VBO repositories."
Can you explain this, please?

Any idea to my second question?

What he meant is that you can backup the Veeam365 Machine with Veeam Backup and Recovery... We do it like this and then back this up to tape for 10 years of retention which is very cheap in comparison to disk.

Wouldn't it be enough, if I do a backup of the .adb Files?

No, only the ADB file will not be enough, it needs all the files within the repository folder.
