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?

Bad encryption algorithm
3DES that is written here shouldn't be used. Beware. Nowadays it is still in usage because there are many high-performance hardware DES-encrypting devices exist and it is very simple to create 3DES encryption (Encrypt(key, Decrypt( key, Encrypt(key,data))). But it is very weak algorithm. Better use is Blowfish, Twofish and of course AES. As I know, OpenSSL can handle them too.
