# Arq Help

## Backing Up Using Administrator Privileges

Arq can back up using administrator privileges. This gets around "permission-denied" types of errors. To set it up, open "Preferences" (from the "Arq" menu) and select the "Advanced" tab.

Check the "Back Up Using Administrator Privileges" checkbox.

### How It Works

When Arq backs up, it launches a "helper" program called "arqcommitter". When you check the "Back up using administrator privileges" checkbox, Arq sets the permissions of the arqcommitter program so that when it's launched, it runs as root.
