This is a simple backup script to use with Duplicity, which must be installed on the system. The script is supposed to backup the user's home directory, encrypt it with the user's key and upload it to a WebDAV service such as Nextcloud or Owncloud.
You can install the script simply by install backup (to install it in the default position, usually /usr/local/bin in Linux distributions) or by install backup path/to/custom/dir to install it in a custom directory.
Once you have installed the script (and your encryption keys have been imported into the keyring), you should create a new directory using mkdir ~/.duplicity. The you should create two files:
- ~/.duplicity/server containing:
DEST="the URL of the WebDAV"
USR="the username"
PSW="the password"- ~/.duplicity/gpg containing:
KEY="the ID of the encryption key"
PASSPHRASE="the passphrase for the encryption key"Remember to properly setup the file permissions: chmod 600 ~/.duplicity/server ~/.duplicity/gpg.
You can edit the user's cron jobs with crontab -e (use crontab -l to view the cron jobs) and then insert the script at the end of it. E.g.: the entry 00 3 * * * /usr/local/bin/backup will execute the script every day of every month at 3 a.m.
