# 22) Automatic Config Backups
### Pre-Work
If you made any changes, you can quickly revert the lab using the **load\_config\_on\_nodes.py** script.
```
python3 load_config_on_nodes.py --lab_dir three-routers --config_filename basic.addressing.cfg
```
### Lab
Connect to R1, and configure the router to backup the config file to an FTP server, with the following parameters:
* Backups should be taken whenever a commit is done, as well as every 24 hours
* Backups should be transferred via FTP to `10.0.0.1`
* Username `user1`
* Password `password1`
* Directory `/backups/juniper` on the FTP server

```
set system archival configuration transfer-on-commit
set system archival configuration transfer-interval 1440
set system archival configuration archive-sites ftp://user1@10.0.0.1/backups/juniper password password1
```
\
Similar to user plain-text-passwords, the password will be automatically hashed:
```
[edit]
admin@R1# show | compare
[edit system]
+ archival {
+ configuration {
+ transfer-interval 1440;
+ archive-sites {
+ "ftp://user1@10.0.0.1/backups/juniper" password "$9$f539AtORcluOds4ZkquO1IEylKM"; ## SECRET-DATA
+ }
+ }
+ }
```
### Explanation
Expand to reveal
This feature is called configuration archival, and it is fairly straightforward. We can configure the router to transfer the configuration upon a commit using `transfer-on-commit`. We can configure the router to transfer the configuration periodically using `transfer-interval `.
\
Note that if you are using SFTP or SCP, you may need to fetch the host-key of the server using `set security ssh-known-hosts fetch-from-server ` from config mode. You don't commit after entering this command; it will immediately grab the host-key.
