# Hooks # Hooks
If you want to perform some commands before and/or after a backup, you can use hooks. If you want to perform some commands before and/or after a backup or restore, you can use hooks.
They consist of a list of commands that will be executed in the same directory as the target `from`. They consist of a list of commands that will be executed in the same directory as the config file or in the `dir` directory if configured.

# Migration from `1.7` to `1.8`
## Config files
- The config version have been changed
- You can now configure restore hooks
See detailed instructions below.
## Config Version
The version field of the config file has been changed from `2` to `3`.
## Hooks
Since `1.8` both backup and restore hooks are possible.
For this reason, backup hooks have been moved one layer deeper, you have to move them in a `backup` object.
Before:
```yaml
locations:
l1:
# ...
from: /foo/bar
hooks:
before:
- pwd
```
After:
```yaml
locations:
l1:
# ...
from: /foo/bar
hooks:
backup:
before:
- pwd
restore:
after:
- echo "My super restore hook"
```
