Last month we didn't do monthly tape backup because of the problem with our tape drives
After problem was solved we took last full disk backup for one of the exchange mailboxes and copied that to tape drive. After copying was complete (370 MB),we tried to do the same with another mailbox, but process failed asking for a new tape
Is it possible to copy backups for all mailboxes (15) to the same tape?
When we did monthly tape backup - we could fit everything on one tape
