## Pruning and snapshot policies
### Pruning and snapshot policies
Autorestic supports declaring snapshot policies for location to avoid keeping old snapshot around if you don't need them.

Pruning can be triggered using `autorestic forget -a`, for all locations, or selectively with `autorestic forget -l <location>`. **please note that contrary to the restic CLI, `restic forget` will call `restic prune` internally.**
Run with the `--dry-run` flag to only print information about the process without actually pruning the snapshots. This is especially useful for debugging or testing policies:
```
$ autorestic forget -a --dry-run --verbose
