Exchange backup Failure

Thread needs solution

So we have been backing up Exchange fine for a couple of weeks...no errors...and then last night these two errors occurred and failed. What do these errors mean?

Storage group or database 'Mailbox Database - Principal' will be skipped during backup on server 'EXCHSERVER.CF.COM'.

Hi Khurram,
the difficulties you've face are of another type and most likely they are caused by insufficient permissions.
Please check this article for detailed information on permissions: http://www.acronis.com/en-us/support/documentation/AcronisBackup_11.5/#…
Thank you,
