SLOOOOW BACKUP

[rgs3]

I'm getting extremely slow backups ranging from 3MB/s to 10MB/s. Replica's SCREAM at up to 1GB/s since they're all incrementals. Its really only the full backups that take really really long time spanning over a weekend and spilling into the work week. The incremental backups range from 10MB/s to 140MB/s which I can live with. I've tested with turning compression off and that looks like it helped just a smidgen.
I am doing Network mode using vStorage API with no encryption. Destination is a remote file server but I've tested backing it up to fast disk locally with no discernible difference in speed. My backup machine is a physical DL380 with quad proc.

Any advice on getting better throughput?

Hi Richard,

It sounds like the performance bottleneck may be related to a source storage. Could you please try to copy/download some big file using vSphere Client > Datastore Browser? What figures do you get?

Thank you!

Downloading directly from the datastore using the vSPhere client I get 25-30MB/s.

Could you please tell us if you see slow backup speed on particular VMs or on all of them? I suggest that you contact our support team directly, as it is hard to troubleshoot the performance issue without seeing the full logs and live environment.

Its all of them. I'll contact support.
