⁠latest

Latest version of backintime (installed from source).

⁠wake-on-lan

Same as latest, but with the additional feature of powering on the backup target with WOL and shutting it down again after the backup. For shutting down the backup target, please have a look at the bottom of this file so see how you have to configure sudoers for the backup target.

⁠Usage

⁠Install

docker pull intelliops/backintime:latest

⁠Running

docker run -ti --name backintime \
  -v /home/<USER>/.ssh/id_rsa:/root/.ssh/id_rsa:ro \
  -v /home:/host/home:ro \
  -v /etc:/host/etc:ro \
  -v /root:/host/root:ro \
  -v /usr:/host/usr:ro \
  --net=host \
  --privileged \
  intelliops/backintime:latest

docker run -ti --name backintime \
  -e MAC=aa:bb:cc:00:11:22 \
  -e INTF=eth0 \
  -v /home/<USER>/.ssh/id_rsa:/root/.ssh/id_rsa:ro \
  -v /home:/host/home:ro \
  -v /etc:/host/etc:ro \
  -v /root:/host/root:ro \
  -v /usr:/host/usr:ro \
  --net=host \
  --privileged \
  intelliops/backintime:wake-on-lan

TODO: remove privileged flag and specify only needed capabilities:

  --cap-add=NET_ADMIN \
  --cap-add=NET_BROADCAST \
  --cap-add=NET_RAW \
  --cap-add=SYS_RESOURCE \
  --cap-add=SYS_ADMIN --device /dev/fuse

The backup process will start immediately after starting the container.

⁠Volumes

⁠Configuration

⁠Environmental variables

Only relevant for wake-on-lan version of the Docker image.

⁠Custom configuration file

To run the backup, you will have to mount the backintime configuration file into the Docker container. An example can be found back in backintime.example.

⁠Backup target sudoers

The backup target is shutdown after a successful backup. For performing the shutdown command, super user permissions are needed. Which means that the following entry has to be added in /etc/sudoers to make this work.

<USER> ALL=NOPASSWD: /sbin/shutdown
