I was happy to see GFS retention available in Veeam 11 for backup jobs (previously only available for backup copy jobs), however, I read it only applies to FULL backups, which means, my retention requirements would require us to have something like 20x the size of our backed up data as backup storage (for each full backup), minus of course compression. I was hoping there would be GFS ability within the same backup chain to alleviate the need for multiple full backups, but appears not?
I have about 100TB to back up. Would I really need to provision 2 PB of backup storage in order to have 10 years retention? Or do I just continue with dailies? Change rate is low, so 365 x 10 incrementals would use considerably less space than (10+12) x full copies. Multiple full backups seem inefficient, but so does having 10x 365 dailies. Or maybe 365 dailies, and annual fulls, but this still requires 10x copies of my data, which seems wasteful when my change rate is low.
I was hoping old incrementals could be rolled up into weeklies, monthlies, yearlies, etc. without requiring a new full backup chain.
Any thoughts, recommendations, best practice advice?
