What is the best way to do automatic incremental backups (and if possible to store more than a single version of the same file) to an external usb hard disk with full hard disk encryption?
I don't want to use the ubuntu backup utility (that provide an encryption feature) because I tested it and it seems really resources intensive and it is not really useful if I need to browse my backup searching for a specific file.
I'm thinking about rsync and cron on a external hard disk with a encryptfs partition but probably there is something better.
I also need to automate in some way the mount/umount process because I don't want to type the password every day to let the backup begin
Thank you! :-)
