iDataGuard allows you to go back in time...

With the iDataGuard online backup service, you can store an unlimited number of versions of the same file (by default, iDataGuard stores the last 10 versions of each file). So, if you have certain files or databases that you update everyday or every week, you can always go back to a previous version if you need to. Go back to yesterday. Go back to last year. Plus, you never again have to worry about accidentally deleting the information in a file or overwriting a file by mistake.

While giving you the power to manage storage space
Of course, you probably won’t want to keep unlimited versions of all of your files because this would use up a lot of storage space. That’s why iDataGuard offers a powerful revision rule wizard that lets you manage how old versions of files are stored. You can set the number of revisions for each file, folder, program or wildcard. So now you can keep an unlimited number of copies of your contact database, while only keeping a few copies of your Outlook PST file.
