preparations

You need restic repository set up elsewhere for trubackup to operate. Consult restic docs to do it.

Before running trubackup make sure that RESTIC_REPOSITORY and RESTIC_PASSWORD are set.

config

You can use example/trubackup.json in repo as a reference. All the sections are mandatory, but you can set mysql, mongo and s3 to empty list if you don't want to backup those.

There's two ways to pass config location to trubackup:

1. Put it in the TRUBACKUP_CONFIG_PATH environment variable
2. Pass it as the value of -c or --config command line flag

If neither is used, trubackup will /etc/trubackup.json as fallback.

backup

Run trubackup backup. The last line in it's output will be backup ID.

list & show

trubackup list and trubackup show are informational commands. You can use the first one to show a list of available backups and the second one to inspect individual backup contents.

restore

Run trubackup restore <BACKUP_ID>. Make sure to replace <BACKUP_ID> with your backup ID.

running regularily

There's example systemd service & timer in systemd/ directory.

deleting old backups

There's contrib/delete_old.py script in this repo that will run restic forget command with arguments adjustable by environment variables. Make sure that you read the script before running it. It is destructive.
