Amol's blog does not mention the BE 15 (and later) Database Encryption Key (DEK) Requirements - so make sure you export this and back this up as well.
If using Backup Set Encryption you should always keep records outside of Backup Exec of the details of the keys used (Passphrases, Encryption Level, Name etc)
Also if you have configured Deduplication and the Deduplication Store still exists then you will need the password and account name used to setup Deduplication (and possble some other details as well) in order to reconnect to the Deduplication Store.
NOTE1: For security reasons it is NOT good practice to keep backups of the DEK with the BEDB backup, or copies of the backup set encryption key details with the backup sets themselves.
NOTE2: It might be better to keep backup copies of the BEDB.bak and DEK outside of tape storage so that you can re-load these files without having to locate the correct tape and inventory/catalog it. At very least keep a manual record of which tapes have your catalogs and BEDB records on them for different dates so that in the event of a disatser you can go straight to the first tape you need.
