**This has to be done only once, regadless of now many cros you have in your config file.**
To actually enable cron jobs you need something to call `autorestic cron` on a timed shedule.
Note that the shedule has nothing to do with the `cron` attribute in each location.
My advise would be to trigger the command every 5min, but if you have a cronjob that runs only once a week, it's probably enough to shedule it once a day.
Here is an example using crontab, but systemd would do too.
First, open your crontab in edit mode
```bash
crontab -e
```
Then paste this at the bottom of the file and save it. Note that in this specific example the `.autorestic.yml` is located in `/srv/`. You need to modify that part of course to fit your config file.
