Replicas and tape backup

[mwant]

We currently create replicas of our VMware VM's instead of backups and are considering implementing back up to tape. I am having trouble finding out whether this is an optimal set up and whether transitioning to backups would be a better idea? Can anyone help?

Hello.
Recommended approach is to have backups besides replicas as in case of data corruption, corrupted data will be replicated to the remote VM.
You need to perform regular backup of VM before copying the backup to tape.
Thanks!

Thanks for your reply. I think we only have enough space for either replica's or backups though so would there be any benefits to tape backups from using backups instead of replica's?

[Shestakov]

Backup and replication are completely different protection approaches.
I would suggest reading this article. Thanks!

Thanks, light is slowly dawning on Marble head.

We probably need to switch to a dual backup strategy where we replicate core VM's for low RTO and backup all VM's for the improved storage use and use the backups for the BUTP.

Not sure what BUTP is, but overall the plan sounds good

Sorry, I meant BUTT, backup to tape!!! Just rubbish I made up

[Shestakov]

Got it. I wouldn't think of tape job if you wrote BUTT initially anyway
Glad we found the solution.
