Backing up your computer files in a timely manner is just as important as purchasing home insurance. Don't make empty promises about irreplaceable digital photos; you should periodically burn these photos onto DVDs. Of course, you can use software or services to do this work, which will make you more efficient. First, you should choose a backup program with an excellent reputation, or start using the free version of SyncBackSE right now, then establish a regular backup schedule to provide "insurance" for your computer hard drive, USB drives, or network drives.
Of course, local backups alone are far from sufficient. To protect your important data, you should also consider factors such as fire, lightning, theft, or other natural disasters. Therefore, you need to back up your data to a remote server via the internet. Currently, Carbonite and Mozy Home both offer unlimited server space, allowing you to back up while you work.
