sh wrapper for duplicity backup

backup2cloud

backup2cloud is an .sh wrapper for automated duplicity backups.
Duplicity is bandwidth-efficient backup solution that creates encrypted tar archives and can write to remote locations using various protocols (FTP, Rsync, WebDAV, SMB, etc.).

backup2cloud is developed and tested on ReadyNAS OS to create backups at Stack using the WebDAV protocol. The software should also run on other debian-based Linux distros. Usage of other remote storage locations and protocols should be possible with minimal adaptations to the configuration file.

Preparations

1. Download and install duplicity

sudo apt-get install duplicity

2. Setup WebDAV connection (optional)

Note: Duplicity supports various file transfer protocols, so this step is not needed if you decide to configure your remote connection differently.

For practicality reasons, a WebDAV folder is mounted (permanently) during boot here. It uses the davfs2 WebDAV drivers, which is also described here.

# Install the davfs2 drivers
sudo apt-get install davfs2
 
# Open the davfs secrets file with your favorite text editor
nano /etc/davfs2/secrets
 
# Add the following line to the "Credential Line" section
https://USERNAME.stackstorage.com/remote.php/webdav/path/to/stack/folder STACK_USERNAME STACK_PASSWORD
 
# Create the WebDAV mount at reboot (fstab doesn't work at ReadyNAS)
crontab -e
@reboot mount -t davfs https://USERNAME.stackstorage.com/remote.php/webdav/path/to/stack/folder /path/to/mountpoint

3. Clone backup2cloud repository

git clone https://github.com/mcoonen/backup2cloud.git
