When you click Backup & Restore from the System administration page, you will be offered a screen that allows you to back up and restore NetWinder system files using your web browser.
When you request a backup, your NetWinder will send you an NWB (NetWinder Backup) file containing all the files you request, stored in a special format. You can later restore these files using the System Restore option farther down the page.
The different types of backups are as follows:
Full system backup. This combines the three options below. It can be as small as 15 megabytes or very large, depending on how many files are stored on the NetWinder.
The full system backup is the easiest way to back up all your files at once.
Home directories. This backs up only the personal files belonging to your NetWinder users. You should do this often (ideally, once a day), in case users delete or damage their files by accident. The size varies depending on how much disk space your users use. It can be as little as 2 megabytes or as much as several gigabytes.
NOTE: This does not include each user's e-mail box, which must be backed up separately.
Configuration files. This only backs up the NetWinder configuration settings. It is important to do this before making any major configuration changes, so that you can restore them if you make a mistake. It's a good idea to keep old versions as well; the file is usually less than 3 megabytes.
User mail spools. This backs up e-mail belonging to your users. It varies in size depending on how much e-mail your users receive, and how much they leave sitting on the NetWinder for long periods of time.
