Jobs Failing to Backup VMs with Code 1722

[dmalishkin]

Hi,

I keep getting this error message on all VM machines. What port or what do i need to do to fix this?

Releasing VM files
RPC function call failed. Function name: [Unfreeze]. Target machine: [10.200.1.31].
RPC error:The RPC server is unavailable.
Code: 1722

Any idea?

I guess second question would be what does VSS really do ? For example if i have a terminal server do i need to enable that VSS option, and if not what should i expect?

Also i have VM that runns exchange 2007, do i need to turn on the VSS then?

please let me know . thank you.

Daniel, I recommend that you read my whitepaper about VSS (available on Veeam website). There is also a number of existing topics on this forum answering questions about VSS, please refer to them for more information.

Yes, I definitely recommend enabling VSS for all Windows-based servers, especially if they are running applications like DC/Exchange/SQL.

From the error it sounds like you have firewall enabled on that VM. Please open a case with our support, and they will help you troubleshoot.
