Most online backup services let you backup pretty much anything you want, but what exactly do you need to backup? Do you also backup software programs?

The following question is one of many you'll find in my Online Backup FAQ:

"I have no idea what I should be backing up. Which programs do I back up? What kinds of files? I'm confused!"

Very simply, you need to back up anything you can't replace. For most people, this means backing up things you've created, like documents, and things you've purchased, like music and movies.

In newer versions of Windows, like Windows 10Windows 8, and Windows 7, these sorts of files are often located in the Documents, Music, Pictures, and Videos folders located within the Users folder with your name but you should check with your other programs to see if they may store files elsewhere.

In OS X on a Mac, you'll find most of your important files in your Documents, Music, Movies, and Pictures folders.

Installed programs themselves, as well as files that are part of the operating system, don't usually need to be backed up because the files don't usually change and can be easily reinstalled. Software programs also rarely work properly when restored from a backup.

If you're still not sure what to backup, know that most online backup service software includes wizards and other preconfigured backup settings that make it easy to select the majority of the important locations on your computer that should be backed up.
