Best Practise for Linux VM Backup/Restore

[Willy]

Hi;

My company recently bought the Veeam Backup/Replication 4.1.1. The backup of the Windows VMs were good running "Virtual Appliance" mode from an NFS shared storage we were getting about 60MB/s backup speed.

We also have some RHEL 4 VMs that we wished to have backup/replicated. May I know what are the best means of performing a backup/replicate of an RHEL4 VMs sitting on NFS shared storage. Any advise will be greatly appreciated.

Currently, I am running the RHEL4 VMs via "Network" mode and am getting about 30MB/s. I have also tried running it in "Virtual Appliance" mode, back it failed, maybe I did not do something correctly.

Apology if this was already covered in any manual. Please direct me to them if possible.

Thanks

Willy

Hello Willy, the Virtual Appliance mode should give you better results with NFS storage. I recommend that you open a support case with us to troubleshoot why it is not working for you. Please provide full logs with the Virtual Appliance mode failure captured. Thanks!

Hi Gostev;

Thanks for your response.

The Veeam backup "Virtual Appliance" mode was failing with HOTADD issues. However, while testing the Veeam backup "Network" mode, my 300+ GB Linux VMs failed when backing up to a datastore. The message was "file size too large" appearing at about 255GB backup. I did some checking and found that the datastore was configured with block size of 1MB, which limits the maximum file size to 256GB.

I reformatted the datastore with a block size of 2MB. The Veeam backup "Network" mode when through successfully. at 30MB/s

Then I retested the "Virtual Appliance" mode and it also when through at 60MB/s

My problem is fixed.
