Backup Errors

Thread needs solution

A backup task that was working fine failed last night. There are about 9 VMs in it. I ran it manually and the same errors were produced for every VM (I have obfuscated the VM name with "X" for privacy reasons):

Any ideas?

Failed to open raw hard disk data file '[Datastore1] XXXXXX/XXXXXX-000002.vmdk'.

To answer myself, this appears to be a "bug" in VMWare related to snapshots, or something not being cleared properly.

To fix it, I logged onto the ESXi host via SSH (I used putty) and ran /sbin/services.sh restart

And now the backup appears to be working.

Maybe you can add this to your knowledge base?
