If you don't have the pass-phrase, the data won't be accessible.
You can try paying someone to recover it, if possible, but this could work out very expensive.
EDIT: Check pkh's response below...if you have your old BEDB you might be able to get it back:
Alternative ways to access Backup Exec Technical Support:
Media Passwords used to only secure the tape header but not encrypt the data, which means there were loads of ways to access the data if you did not know the password.
Encryption Passphrases scramble every block of data as it is written to the tape, as such no passphrase does mean no restore even by a data recovery company.
Is possible to recover ky phrase from old directory installation backup exec 2010 ???? how
Check pkh's response in the link I posted, and if that doesn't help, then it won't be possible as mentioned!
what is my old BEDB???
I have a copy of a old installation directory backup exe 2010!!
BEDB = Backup Exec Database
If you read my suggestion...check the link I posted. If you can't do what pkh's solution states, then you won't be able to recover your passphrase, and having a copy of the BEDB or installation directory or anything else means nothing. If you forget the passphrase, and there is no other way of getting it back, your data is lost.
If you have a copy of the subfolders of the installation folder then assuming no customized paths were involved there shoudl eb a copy of BEDB.bak in the data (sub)folder
This can be used to take yoru backup exec install back to a date/time when the passphrase existed
- if trying to do this on a production server then you MUST take appropriate steps to protect the newer media server config, history and backup sets prior to recovering the old database. Failure to do this may cause newer backups to be overwritten by accident. RECOMMENDATION: With tapes always use the write protect tabs when doing operation like this
- if the passphrase was restricted and the user accounts involved in it's creation no longer exist then you may have complications even if you do have the bedb.bak
- the process does not recover the actual passphrase, you have to use the recovered database to do any needed inventory, catalog and restore operations
- it is difficult for us to give any step by step notes via the forums as the specifics of your scenario will change any exact steps we might try to provide.
