9.4.4. Encrypt data

Now you can encrypt a .tar archive or a compressed archive, prior to saving it to a backup medium or transporting it to the backup server. Use the gpg command like this:

gpg -e -r (part of) uid archive

The -e option tells gpg to encrypt, the -r option indicates who to encrypt for. Keep in mind that only only the user name(s) following this -r option will be able to decrypt the data again. An example:

willy@ubuntu:~$ gpg -e -r Willy /var/tmp/home-willy-20060808.tar
