While a large part of my backup system currently consists of manually mirroring pictures to various solid state media (that occasionally are moved to separate fire zones) - and a good helping of prayer/good luck - the part which is set up uses duplicity driven by backupninja (from Debian repos - upstream is): https://0xacab.org/riseuplabs/backupninja https://0xacab.org/riseuplabs/backupninja It was complicated to set up separate signing and encryption keys such that the server sending backups could not decrypt (assuming the symmetric session key wasn't somehow kept around). But once setup the only worry was making sure the backup server didn't run out of space.
