duplicati

description:

Duplicati is an application that manages backups. It supports many platforms and technologies. I simply use it to create regular backups of my data to external locations. The backup is encrypted to secure it.

source and credits: docker image - duplicati/duplicati from Duplicati

usage

The Duplicati web interface facilitates an easy configuration of your backups. It also provides a view of the status and logs and in case you need it an ability to restore data from a recent backup.

It is important to test you restoration ability to ensure you are covered for the inevitable.

dependencies

The folders you need to backup and the target sources need to be added as volumes in the container. In the configuration below, I refer to /media/2tb which is a symlink to one of my external drives.

installation

create a stack in portainer with the following code.

 version: '2'

   duplicati:

tips

Be sure to review your backups regularly a) to make sure they are working and b) to make sure you are backing up everything you may need in case of a disk failure.

Also consider the case where your computer may be physically removed or damaged. Ie: a cloud backup or backup to a different location. Duplicati supports this well.
