Backup Central

I'm sorry if this has been asked before.

I'm running a Scalar 50 with HP LTO-4 Drives. I want to encrypt the
data that is put on the tape, We already have encryption going between
the Dir/SD and FD's. I just want to encrypt the data that will be
placed on Tape for OffSite storage.

Has anyone done that or know some pointers to point me to so I can get
this working?

Thanks!

I don't have an LTO-4, but as I recall, LTO-4 drives can implement
encryption on the drive itself--I'm not sure this is sufficient for your
purposes, or how to make bacula do it, but doing the encryption in the
drive would likely be better for performance (drive compression would
happen before encryption, bacula's encryption may well be
single-threaded, etc).

bacula encryption takes place on the file-daemon. Encryption on the
storage-daemon is not supported (... yet, it's on the projects list
http://www.bacula.org/git/cgit.cgi/bacula/plain/bacula/projects?
h=Branch-5.2)

as Steve said, (some?) LTO tapes support on-drive encryption. never used
it by myself.

Most of the LTO-4 and LTO-5 drives support encryption in hardware. To
make this work however there needs to be support for this in the backup
software you're using.
This is necessary for determining and managing the keys used as well as
enabling the encryption. Currently bacula is not able to do this, only a
few commercial backup solutions offer this.
