A very simple suite of backup scripts for Duplicity

This is a very simple and rough suite of backup scripts acting as a front-end for Duplicity:

• backups.sample.conf - Sample configuration file.
• backups.conf - Your configuration file.
• rsync-backup - Main backup script that parses backups.conf. Performs backups and outputs to log.
• rsync-backup-command - Run any command against Duplicity using the configuration defined in backups.conf
• rsync-archive-logs - tar/gzips old logs in the log directory.
• rsync-cleanup-prune - Runs the cleanup and remove-older-than 30D Duplicity commands on each backup point defined in backups.conf.
• rsync-verify-backup - Runs the verify Duplicity command on each backup point defined in backups.conf.

Requirements

• Duplicity - http://duplicity.nongnu.org
• GnuPG (for encrypted backups)
• bash, tar, rm
• A remote backup location (local host or a remote host via protocol supported by Duplicity. See duplicity documentation)

Installation

• Install Duplicity. This is also usually available from package managers.
• If you wish to encrypt your backups, create and configure an asymmetric key pair using GnuPG. See GnuPG Documentation for details.
• git clone this repository to a directory of your choice.
• Use backups.sample.conf to configure your backups. Rename and save in same directory, with filename backups.conf.
• Use crontab -e or other method to schedule the backups; sample crontab is below.

Suggested crontab

Here is a sample crontab with weekly full backups and daily incremental backups.

# Daily backup (Mon-Sat inc backup)
30  0    *   *   *   /home/jfritz/backup-scripts/rsync-cleanup-prune
0   1    *   *   1-6 /home/jfritz/backup-scripts/rsync-backup inc

# Weekly full backup (Sunday)
0   2    *   *   0   /home/jfritz/backup-scripts/rsync-backup full

# Monthly Log Cleanup
0   3   1   *   *   /home/jfritz/backup-scripts/rsync-archive-logs

**Caution: ** Be careful about putting rsync-verify-backup in your crontab; the Duplicity verify command downloads backups and decrypts them in order to verify them.
