Backup

From xat wiki

The Backup power allows you to have regular backups of your group's staff (members, mods, owners, main owners), guests and banned users (including, but not limited to: dunces, redcards, yellowcards) sent to the email that was used to activate the group. These backups are also known as your group CSV data or .xatu file (you can find more info at Manage about these files).

Note: You won't get an email unless there have been any changes to the backup file.
