Duplicity backup

Esimerkiksi näin voit varmuuskopioida /home -hakemiston. Crontabiin sopivalla välillä:

duplicity full --ssh-options="-oProtocol=2 -oIdentityFile=/home/tunnus/.ssh/id_dsa" --timeout 50000 /home scp://tunnus@kapsi.fi//home/users/tunnus/siilo/backup && duplicity --force remove-all-but-n-full 1 scp://tunnus@kapsi.fi//home/users/tunnus/siilo/backup

Voit myös käyttää salasanaa seuraavalla syntaksilla: ssh://user[:password]@other.host[:port]/[/]some_dir

Voit rajoittaa kaistankäyttöä trickle-sovelluksella. Manuaalista:

--encrypt-key key-id: When backing up, encrypt to the given public key, instead of using symmetric (traditional) encryption. Can be specified multiple times. The key-id can be given in any of the formats supported by GnuPG; see gpg(1), section "HOW TO SPECIFY A USER ID" for details.
--encrypt-secret-keyring: This option can only be used with --encrypt-key, and changes the path to the secret keyring for the encrypt key to filename This keyring is not used when creating a backup. If not specified, the default secret keyring is used which is usually located at .gnupg/secring.gpg
--encrypt-sign-key key-id: Convenience parameter. Same as --encrypt-key key-id --sign-key
--gpg-options: Allows you to pass options to gpg encryption. The options list should be of the form "opt1=parm1 opt2=parm2" where the string is quoted and the only spaces allowed are between options. key-id.
