| How often should you backup your data? |
|
Backing up your computer involves placing a duplicate copy of your data onto a secondary media, such as CD, DVD, external hard drive or an online server or Web site. If your hard drive fails or you accidentally delete a file, you can rely on the backup to recover files. Depending on the number of files you work with and the frequency in which they are modified or created, you can do a backup as often as every day or as infrequently as every quarter. If you work with files that are updated daily, then you should back up daily. You should also do an extra back up whenever you perform any delicate tasks on your computer, such as formatting a hard disk or upgrading a piece of hardware.
