"How do I make sure only authorized person access my
backups stored on the tape drives (DAT, DLT, LTO-4 etc) under Linux
or UNIX operating systems? How do I backup /array22/vol4/home/ to
/dev/rmt/5mn or /dev/st0 in encrypted mode?
"You can easily encrypt data to tape using combination of tar
and openssl commands. The following is software based solution
based upon encryption algorithms supported by openssl tool.
Encrypted backup should be used when storing sensitive data on
removable media or when storing backups on shared NAS / SAN servers
or online backup servers. When using encryption the openssl ask for
a password before you can create, view, open, or restore the files
included in the backup. This is based upon pipes concept."
