AceBackup supports several versions of stored and restored files. This inconspicuous feature can yield an enormous profit:
For example, if you have backed up a damaged document by mistake, the wrong version of your file will be stored on your hard disk as well as during your backup which means that the content will be definitely lost.
With a multi versioning backup you can avoid such a scenario. It enables you to store and restore a file in serveral versions. In the case mentioned above you can easily restore an older version of your file.
