I'm intermittently getting an error when backing up my VM's to an external drive. The backup appears to run successfully, and my 1st HyperV host is backed up successfully every time, however the 2nd one seems to fail. The error information is below.

The backup vault is password protected

Command 'Running backup plan 'Cluster - Both Nodes - all VM's to External'' has failed.

Anyone able to shed some light on the cause?

The error indicates that the 2nd location (\\hmp-pdc01\e$\) cound not be opened over network with standard system error. If it fails intermittently then it could be that at the given time the external drive (which I assume is e$) is inaccessible. It can be caused for example by multiple connections opened to this share at the same time. You can try setting a different time for backup of the 2nd host + remember to specify credentials to this share in hostname\username format.

Thank you.
