Hi,
We use Veeam to backup our VMWare environment, then Backup Exec shoves everything onto tape for offsite storage.
If you're not familiar with how Veeam works, it creates one big backup file of the VM which is updated everyday with the latest changes, then creates a smaller separate file with just the changes in it, so you can roll back to a point in time. So as we have Veeam set to keep backups for 30 days, we have one big 400gb backup files, then 30 smaller change files dated for each day in the previous month.
Currently, Backup Exec puts all this onto tape everyday, amounting to approximately 1TB. What I'd like to do instead, is to backup just the files modified in the previous 3 days, that way we'd get the full backup file, along with the previous 3 change files, which would put us at about 500gb.
The closest I can see to this is the Backup Exec "Working Set" backup, and setting it to backup the files accessed in the previous 3 days. Unfortunately this won't work for us, as each time the Veeam service restarts, the Accessed time is updated.
In short, what we'd really like is to do a Working Set backup, but using the file Modified date, instead of the Accessed.
Any ideas how I could do this?
Thanks!
Ben
