Overview

runrestic is a simple Python wrapper script for the Restic backup software that initiates a backup, prunes any old backups according to a retention policy, and validates backups for consistency. The script supports specifying your settings in a declarative configuration file rather than having to put them all on the command-line, and handles common errors.

Here's an example config file:

repositories = [
    "/tmp/restic-repo",
    "sftp:user@host:/srv/restic-repo",
    "s3:s3.amazonaws.com/bucket_name"
    ]

[environment]
RESTIC_PASSWORD = "CHANGEME"

[backup]
sources = [
    "/home",
    "/var"
    ]

[prune]
keep-last =  3
keep-hourly =  5

For a more comprehensive example see the example.toml or check the schema.json

Getting started

To get up and running, first install Restic.

To install runrestic, run the following command to download and install it:

sudo pip3 install --upgrade runrestic

Note that your pip binary may have a different name than pip3. Make sure you're using Python 3, as runrestic does not support Python 2.

Once you have restic and runrestic ready, you should put a config file in on of the scanned locations, namely:

• /etc/runrestic.toml
• /etc/runrestic/example.toml
• ~/.config/runrestic/example.toml

Afterwards, run

runrestic init # to initialize all the repos in `repositories`

runrestic  # without actions will do: runrestic backup prune check
# or
runrestic [action]

Autopilot

If you want to run runrestic automatically, say once a day, the you can configure a job runner to invoke it periodically.

cron

If you're using cron, download the sample cron file. Then, from the directory where you downloaded it:

sudo mv runrestic /etc/cron.d/runrestic
sudo chmod +x /etc/cron.d/runrestic

systemd

If you're using systemd instead of cron to run jobs, download the sample systemd service file and the sample systemd timer file. Then, from the directory where you downloaded them:

sudo mv runrestic.service runrestic.timer /etc/systemd/system/
sudo systemctl enable runrestic.timer
sudo systemctl start runrestic.timer
