Ah, interesting. You might also check the zmanda wiki for more recent
advice.
I have not experimented with encrypting the backups as they are made in
this manner, so maybe someone else can chime in.
I conjecture that once you start making backups with encryption, the
older dumps will not be immediately recoverable because they are not
encrypted. If so, then starting over might be a good idea.
Or you could proceed, knowing that you will have to change the dump type
back to the unencrypted to recover old dumps. If you do monthly or
annual snapshots, document that well!
I solve the problem of encrypting my backups with a different
mechanism. I back to disk, and rsync to another disk for offsite backup.
I encrypt the file system on the offsite disks with ecryptfs.
amanda do not use the dumptype when restoring, it use the information in
the backup.
It decrypt only encrypted backup.
if you enable encryption, the newer backup are encrypted, older backup
are still unencrypted and they are restorable.
