I would like to ask for your help identifying the following issue : Restoring a backup is dreadfully slow at 15Mb/sec.
While the daily backup creation job peaks at 300 Mb/sec.
Restoring a VM at this rate takes hours, and restoring them all would take days.
The environment :
- Veeam B&R 6.5
- ESXi 5.0.0
What I have tried so far, unsuccessfully :
1) Disabling the antivirus
2) Disabling VAAI (VMware vSphere Storage APIs Array Integration) by following these steps for the relevant ESXi in vSphere Client :
- Moving DataMover.HardwareAcceleratedInit from 1 to 0
- Moving DataMover.HardwareAcceleratedMove from 1 to 0
- Moving VMFS3.HardwareAcceleratedLocking from 1 to 0
I would upgrade ESXi 5.0.0 to 5.5.0u3 but Veeam 6.5 isn't compatible with anything past 5.0.0 so for now this isn't an option. Old software, I know.
