We currently two Veeam servers, each in it's own DC, backing up local VMs for a few weeks, with daily backup copy jobs to each other. I want to obtain longer retention for no other reason really than the concern that risks such as ransomware may not come out of the woodwork for weeks.
So, I'm exploring the most cost effective way to keep regular backups on tape/disk.
We do have a tape drive in one of the sites but it's "owned" by another backup solution - Veritas - so Veeam can't "own it" for it's own purposes.
I'm thinking of simply doing monthly file level backups to tape (using Veritas) of the Veeam full vbk backups and the backup copy vbk files.
1. Does this appear like a sound strategy?
2. How backward compatible are the Veeam backup files? (i.e. if I try restoring Veeam 9 backups to a later Veeam 10 server will that work?)
3. Does anyone have any better ways or suggestions?
