Oops!Backup is an easy-to-use backup tool with versioning support that will automatically back up new and changed files in the folders you specify.
The program is straightforward to configure. Just tell it the folders you'd like to protect (Document, Pictures and Music, say); how frequently you'd like your backups to be made (the default is hourly, but you can set this to whatever you like); and where they should be saved. An external drive is best, but you might also use a network drive, your main PC drive, and even a USB flash drive can offer useful protection.
And once it's all set up, there's nothing else to worry about. No scheduling, no complicated options, Oops!Backup simply runs in the background, protecting new and changed files as they appear.
If you do need to restore something, simply choose the appropriate folder in Oops!Backup. A search option and preview window makes it easy to find whatever you're looking for. And you're able to restore multiple versions of a document, too.
So if a week last Tuesday you accidentally deleted some important part of a Word document, and you've only just noticed, it's not a problem. In a few seconds you can recover that version of the document, paste the missing section into the latest copy, and you're immediately back in business.
