Restore Speed

[ftbug]

Hi, we have recently ran a small scale DR test with a couple of machines with varying size, which have all been restored from the same cloud server, to the same destination/storage array.

My question is, why do VMs restore at different rates?

We have restored 4 machines (from 90GB disks to 350GB) which have all ran at around 112MB/s, however, when restoring a larger machine (all disks add to around 4TB), we only seem to get a throughput of around 35MB/s? It seems strange because a 90GB disk on this machine transferred so much slower than a separate machine also with a 90GB disk.

Any ideas would be much appreciated

Hi,

That depends on transport mode and proxies used during restores. Also which version do you use? Please describe your backup infrastructure configuration and hardware.

Thank you.

Restore speed also depends on the VM disk type (thin/thick), their contents, and some other factors as well.
