# 🎛 Config File
## Path
By default autorestic searches for a `.autorestic.yml` file in the current directory and your home folder.
- `./.autorestic.yml`
- `~/.autorestic.yml`
You can also specify a custom file with the `-c path/to/some/config.yml`
> **⚠️ WARNING ⚠️**
>
> Note that the data is automatically encrypted on the server. The key will be generated and added to your config file. Every backend will have a separate key. **You should keep a copy of the keys or config file somewhere in case your server dies**. Otherwise DATA IS LOST!
## Example configuration
```yaml | .autorestic.yml
version: 2
locations:
home:
from: /home/me
to: remote
important:
from: /path/to/important/stuff
to:
- remote
- hdd
backends:
remote:
type: b2
path: 'myBucket:backup/home'
env:
B2_ACCOUNT_ID: account_id
B2_ACCOUNT_KEY: account_key
hdd:
type: local
path: /mnt/my_external_storage
```
## Aliases
A handy tool for more advanced configurations is to use yaml aliases.
These must be specified under the global `extras` key in the `.autorestic.yml` config file.
Aliases allow to reuse snippets of config throughout the same file.
The following example shows how the locations `a` and `b` share the same hooks and forget policies.
```yaml | .autorestic.yml
version: 2
extras:
hooks: &foo
before:
- echo "Hello"
after:
- echo "kthxbye"
policies: &bar
keep-daily: 14
keep-weekly: 52
backends:
# ...
locations:
a:
from: /data/a
to: some
hooks:
<<: *foo
options:
forget:
<<: *bar
b:
from: data/b
to: some
hooks:
<<: *foo
options:
forget:
<<: *bar
```
