NAS Backup Netapp Integration - Best practices

Post by stede »

Hi,

We are running VBR 11 and like to backup some SVMs / vservers from our Netapp AFF Filers.

We are very interested in real world experiences and best practices.

1. How many volumes / shares should be configured in one backup job max?
(We could provide the number and size of the files)
2. We would like to back up another NAS SVM with approx. 90 volumes / shares.
a. Can the rescan process cause problems in a productive environment on our Netapp Filers?
(see also https://helpcenter.veeam.com/docs/backu ... ml?ver=110)
b. Is there any advantage in increasing the Rescan Scope step by step?
3. When should I adjust the Backup I / O Control in the File Share settings?
(see also https://helpcenter.veeam.com/docs/backu ... ml?ver=110)
4. Which values should be monitored on the Netapp filers?

I know that it always "depends" but some hints would be nice.

Thanks in advance.

Hello,
which protocol are we talking about? For NFS there is less to think about than about SMB. For SMB, having more than one proxy can be useful if you have large shares (SMB has limitations on "performance per IP address")

1. Number of files / size would help, yes. Also the required RPO time. Without further information, 50TB should be a good starting point per job. Then see how the infrastructure is doing and increase to 100TB per job.
2a. That is just infrastructure discovery. The main load results from backup.
2b. Less waiting time before you can create your first job. I would exclude "other volumes" if you are not backing them up with Veeam. For 90 volumes, the scanning is relatively irrelevant.
3. if you want faster / slower backup
4. the same values you monitor during normal operations. I mean, load is expected during backup. Netapp AFF systems should hopefully be fast enough to be able to deal with backups (disk based systems have more performance issues).

Hope that helps,
Hannes
