Hi Vicky
There is no way to recover a passphrase, anyone using Encryption should document their passphrases and store that documentation in a firesafe (or at very leats at a separate location)
To cover for your existing data you should make sure you backup the Backup Exec database regularly and recover that. I would also suggest that if you can, you change the passphrase to Common as it will make things slightly easier if the original account that created it no longer exists
Also, I would recommend not encrypting however you backup the Backup Exec database as it you mess up the encryption of this backup you will have no way back.
Finally you should follow Donald's advice, change any existing backup jobs that use a passphrase you don't know to one you do and document the date of the change to be kept with the passphrase so you know when to use which passphrase.
I repeat there is no ability to recover the details of a passphase, this is becuase the whole point of encryption is to make data impossible to read without knowing the security phrase.
