 # Backup
 
 ```bash
-autorestic backup [-l, --location] [-a, --all] [--dry-run]
+autorestic backup [-l, --location] [-a, --all]
 ```
 
 Performs a backup of all locations if the `-a` flag is passed. To only backup some locations pass one or more `-l` or `--location` flags.
 
-The `--dry-run` flag will do a dry run showing what would have been deleted, but won't touch the actual data.
