Output of the two commands below.
The only warnings I've had in the backups have been if for some reason there are no active mailboxes on that specific server when it's backed up. If that happens there's a warning from the Symantec VSS writer that there's no active databases on that particular host (as expected).
In this specific backup, half the databases were on EX01 and half on EX02 so I thought this was why there was two VMware backups taken (one of EX01 and one of EX02) and there are two restore points for Exchange data for that date (each with half the databases in).
The exchange data images appear to be there, the VMware images of the underlying Exchange VMs seem to be there, but it's like it's struggling to tie the two togther.
I assume the MS-Exchange-Server images are "virtual", generated based on the one-pass VMware backup?
