The short answer is no, the longer answer is it is possible but not without
additional software/hardware. Basically two choices.
1) get a tape library with the encryption feature and encrypt tapes as they
are written. Encryption done by the device. Many VTLs have that built
in.
2) The other option is to use one of the tape management software
offerings. We use BRMS, and you'll need the advanced feature. BRMS then
encrypts the tape as it's written but the encryption happens on the host,
not the tape library, and the same encryption key is used for all tapes.
The encrypt at the Library method will encrypt each tape differently.

Advantages/disadvantages both ways but the one thing that's common to both
of them is DO NOT LOSE THE ENCRYPTION KEYS! If you do, you have worthless
mylar or disk files on a VTL.

With base IBMi 7.3 and a standard LTO7 drive, is it possible to encrypt
backups, or is additional hardware/software required?
