encrb backs up plaintext local directories to remote machine as encrypted, using encfs --reverse and rsync.

$ ./encrb $HOME/documents $HOME/projects some.server.eu:/home/user/backups/

First run will generate a random password, save it to PASSFILE and prompt for encfs settings (pressing enter picks the defaults). Encfs KEYFILE is also created. Further runs will not require any user input.

$ ./encrb --help
Usage: encrb [options] dir-to-back-up1... remotepath

Options:
  -h, --help            show this help message and exit
  -k KEYFILE, --keyfile=KEYFILE
                        encfs keyfile to use [~/.encfs6-encrb.xml]
  -p PASSFILE, --passfile=PASSFILE
                        file containing encfs keyfile password [~/.encfs-
                        password]
  -b BWLIMIT, --bwlimit=BWLIMIT
                        Bandwidth limit (KiB/s) for rsync [0]

Remember to back up the keyfile and the password! If you lose them, you will lose access to the encrypted data. Naturally you should not back up the keyfile to the same place where you put the actual backups. And it is a very good idea to have multiple backups of the keyfile (and password). For maximum security, keep the data, the keyfile and the password at different locations.

You most likely want to run encrb from crontab. I recommend using flock or something similar to make sure no multiple instances are running, like this:

30 0 * * * flock -n /tmp/encrb.lockfile /path/to/encrb --bwlimit 100 $HOME/docs $HOME/projects some.server.eu:/home/user/backups/

• encfs 1.7.4 or later
• python
• rsync
