Data backup is the process of backing up the files on your computer in case your PC crashes or you get a computer virus. There are several different types of backup. Using a backup software solution like NovaBACKUP will allow you to back up your files, photos, music, and email to a local or online location. You can also use the copy files function to create a backup copy of your files in their native file format. You can also create a Disaster Recovery backup which allows you to recover your entire system, including files, applications, settings and your operating system. Most people will create a backup plan that includes both full and incremental backups to ensure that as new files are created or saved their data is protected without having to do a full backup every time (which saves time and space).
