# Hot copy back up and restore

> Perform back up and restore operations while the server is running.

Perform the hot backup and restore operations for your Unity Version Control (UVCS) server. Both of these operations require you to [enter read-only mode](../readonly-mode).

> **Note:**
>
> You can also create a hot copy with [`rdiff`](./rdiff-backups).

### Backup

1. Set the UVCS server to read-only mode (`cm admin readonly enter`).
2. Backup the Jet content. You can find the content in the `basepath` parameter specified during the [database setup](../configure/repository-storage) (check the `jet.conf` file).
3. Leave read-only mode (`cm admin readonly leave`).

### Restore

1. Set the UVCS to read-only mode (`cm admin readonly enter`).
2. Restore all the backup files to the path you configured (remember to [set the path](../configure/repository-storage#use-the-jet.conf-file) in the `jet.conf` file).
3. Leave read-only mode (`cm admin readonly leave`).
