We recently performed some maintenance on an ESXi cluster we backup using VM Explorer 6.3. A couple of VM's were vMotioned during the maintenance, and ESXi was patched on the whole cluster. All the backups are working except for two VM's that are reporting an error I've never seen before;
Failed: Unable to find a virtual disk which match with the snapshot information <servername>
Nothing else is logged, but the backup just fails. All other VM's in the cluster backup fine. There aren't any outstanding snapshots on the VM's, I've tried removing and re-adding them to the task too. No change. Any ideas?
The VM Explorer Logs (in C:\ProgramData\Trilead\VMX\log) and the ESXi hostd should help you to analyze what causes this issue. In case you do not get any further by doing so, please open a support case and we will be happy to help you.
