+First and foremost - *encrypt your USB drives*! Even if you think you have "/nothing to hide/" if you accidentally lose a USB thumb drive (it's easy to lose small objects) and it's not encrypted then potentially someone might be able to obtain enough information about you to commit identity fraud, take out loans, open bank accounts, etc. Use LUKS encryption. In Ubuntu you can do this using the /Disk Utility/ application. Some instructions [[https://help.ubuntu.com/community/EncryptedFilesystemsOnRemovableStorage][can be found here]].

 When the backup ends remove the USB drive and keep it somewhere safe. Even if it gets lost or falls into the wrong hands the content is encrypted and so is unlikely to become a source of leaks.

 Distributed backups are a better way of ensuring the persistence of your data, such that even if your system gets stolen or destroyed then the data will still be recoverable from your friends. Since the backups are encrypted your friends (or anyone else with access to their systems) won't be able to read your backed up content even if their systems are subsequently compromised.
