# Update a backup global configuration

PATCH https://api.modulards.com/api/public/v1/preset-backups/{preset_backup}
Content-Type: application/json

Updates one backup global configuration. Send only the fields you want to change.

- `schedule` is replaced whole: when you send it, it carries every field it needs (`frequency`, `start_hour`, `timezone` and the day its frequency asks for); when you leave it out, the stored one stays.
- The frequency, the retention and `incremental` are validated together, using the stored value of the ones you leave out.
- A new schedule reaches every website that uses the configuration and reschedules their next backup. A new `retention_period` moves the expiry of the backups those websites already hold, so a shorter retention brings deletions forward.
- `default: true` makes it the configuration new websites receive and takes the mark off the previous one; `default: false` clears it.
- The technical batch sizes are not part of this API: the configuration keeps the ones it has.

**Body**

All fields are optional and take the same values as in "Create a backup global configuration".
- `name` (string, optional): the configuration's name.
- `region` (string, optional): where the backups are stored.
- `schedule` (object, optional): `frequency`, `start_hour`, `timezone` and the day its frequency asks for.
- `retention_period` (integer, optional): days each backup is kept.
- `incremental` (boolean, optional): daily schedules only.
- `exclusion` (object, optional): `extensions` and `max_file_size`.
- `default` (boolean, optional): whether new websites receive it.

**Errors**
- **422**: `retention_period` is not allowed by the stored frequency, a weekly `schedule` is sent to a configuration that still has `incremental` on (send `incremental: false` with it), or `batch` is sent.
