Tape Encryption
Hi guys:
I've been trying to find information about how to encrypt a backup to tape (I'm using a couple of simple commands: tar, find | backup), I didn't find a real example of how to do that, just a couple of white papers and information about the methods that use the backup, policies, etc.
I don't know also if there's a free-cost solution and the solutions presented has the problem that I need an intermediate server (for example using TKM Tivoli Key Manager), so in a case of a real recovery I will need this server for restoration. I don't want a complex solution, since I only have one tape drive (and one backup), I just need to encrypt one tape and have a simple solution to restore it in another site (without the fear that if the tape is stolen, somebody could restore).
Does exists a solution like that? Any recommendations will be welcome.
Thanks!

amrmtape
AMRMTAPE(8) System Administration Commands AMRMTAPE(8)
NAME
amrmtape - remove a tape from the Amanda database
SYNOPSIS
amrmtape [--changer changer-name] [--cleanup] [--dryrun] [-n] [--erase] [--keep-label] [--quiet] [-q] [--verbose] [-v] config label
DESCRIPTION
Amrmtape invalidates the contents of an existing backup tape in the configuration database. This is meant as a recovery mechanism when a
good backup is damaged either by faulty hardware or user error, e.g. the tape is eaten by the drive or is overwritten.
See the amanda(8) man page for more details about Amanda.
OPTIONS
--changer changer-name
Specify which changer to use when erasing label
--cleanup
Remove logs and indexes associated with label. Otherwise, they'll remain until the next run of amdump.
--dryrun, -n
Generate new tapelist(5) and database files with label removed, but leave them in /tmp and do not update the original copies.
--erase
Attempt to erase the data contained on the volume with the given label. This requires that Amanda be able to find that volume using the
tape changer. Erasure is not supported by all Amanda devices, and the erasure is not "secure" in the sense that the data can most
likely be recovered by someone with the right tools.
--keep-label
Do not remove label from the tapelist.
--verbose, -v
List backups of hosts and disks that are being discarded. Enabled by default.
--quiet, -q
Opposite of -v.
EXAMPLE
Remove tape labeled DAILY034 from the DailySet1 configuration.
# amrmtape DailySet1 DAILY034
