Backing up your information
As you add new software and data files, you should back up your system on a regular basis to
maintain a reasonably current backup. Back up your system at the following times:
At regularly scheduled times
NOTE: Set reminders to back up your information periodically.
Before the computer is repaired or restored
Before you add or modify hardware or software
Note the following when backing up:
Create system restore points using the Windows® System Restore feature, and periodically
copy them to disc.
Store personal files in the Documents library and back up this folder periodically.
Back up templates stored in their associated programs.
Save customized settings in a window, toolbar, or menu bar by taking a screen shot of your
settings. The screen shot can be a time-saver if you have to reset your preferences.
To copy the screen and paste it into a word-processing document, follow these steps:
1. Display the screen.
2. Copy the screen:
To copy only the active window, press alt+prt sc.
To copy the entire screen, press prt sc.
3. Open a word-processing document, and then select Edit > Paste.
4. Save the document.
You can back up your information to an optional external hard drive, a network drive, or discs.
When backing up to discs, use any of the following types of discs (purchased separately): CD-R,
CD-RW, DVD+R, DVD-R, or DVD±RW. The discs you use will depend on the type of optical
drive installed in your computer.
NOTE: DVDs store more information than CDs, so using them for backup reduces the number
of recovery discs required.
When backing up to discs, number each disc before inserting it into the optical drive of the
computer.
