auto-restic

Simple, automated restic backups through configuration files.

Usage

A configuration file is automatically generated during the first run, if one isn't present.

An example configuration file looks like this:

config = {
    "restic-repo": "path/to/restic/backup/repository",
    "restic-password-file": "configuration/restic-password.txt",
    "backup-file": "configuration/paths-to-backup.txt",
    "exclude-file": "configuration/paths-to-exclude.txt",
    "backup-frequency": 21600,
    "keep-backups": -1,
    "backup-on-start": true,
    "last-backed-up": 1234567890
}

• restic-repo: The path the restic repository resides in. If one doesn't exist, initialize one.

• restic-password-file: The path to the text file containing the passoword to your restic repository.

• backup-file: Text file containing the paths that will be backed up, one per line.

• exclude-file: Text file containing the paths that will be excluded from the backup, one per line.

• backup-frequency: How often you want to run the backup, in seconds.

• keep-backups: How long to keep the backups for. See restic's documentation for --keep-within duration. Set to -1 to never remove backups.

• backup-on-start: Set this to true if you want the script to run a backup every time it's started.

• last-backed-up: Keeps track of when the last backup was performed, so a backup won't be started if you restart the script immediately after a backup.

Running

You should run the program once in the foreground to create a configuration: this can be done with python3 auto-restic.py.

The simplest way to run the script in the background is either through screen on nohup. With nohup, running the program is as simple as nohup python3 auto-restic.py &.
