Hi,
I’m new to Veeam family and doing initial deployment.
What is recommendation for backup jobs - one job for one VM? or group more VMs which could be same schema of backup in one backup job? how much it affects deduplication?
Is ReFS deduplication compatible with also enabled job deduplication? Could be both enabled?
Is there any report of job deduplication? for me it looks it does not deduplicate anything.
Thanks
Group VMs with similar backup needs in one job it improves deduplication and simplifies management.
ReFS block cloning works with Veeam’s job-level deduplication, and both can be enabled.
Deduplication stats are visible in job logs or via Veeam ONE.
Hi
Veeam does compression and deduplication per VM backup chain. So from that point of view it doesn’t matter how you group your VM in your backup jobs.
In general I would try to keep it simple and not configure too many jobs. Group VMs according to their retention or backup schedule, and keep the jobs dynamic.
While ReFS deduplication is possible, it’s not recommended because of it’s performance implications. With Fast Clone and Veeam’s own compression/deduplication there’s also no high need to have global deduplication enabled.
I wouldn’t recommend doing multiple layers of deduplication. Sure, you make eek out slightly more storage savings, however, it may slow down both your backups and restores significantly.
In fact, there are also some settings available in the storage tab of backup jobs that optimize for deduplication targets.
