You have two very simple ways to do backups in your HDA.

[edit] Full Disk Backups

The HDA now includes the Personal Backup Appliance, or PBA, with the collaboration of the PBA leader, Roland Hui.

This application is a hard disk clone, backup and restore application.

[edit] Periodic File Backups

One of the ways to backup systems in your network is to use the operating-system provided backup system.

We have documented how to do periodic file backups in Windows Vista on to your HDA.

We also have a section for Windows XP and Ubuntu's Simple Backup.
