intervals. You can schedule a job to run every certain number of minutes, on certain days at a specified time, 
or whenever any data in the backup source are modified.
Shadow can also be configured to archive file versions. If this option is enabled, then any file that is saved or 
overwritten will trigger Shadow to archive the previous version of the file. The file versions are stored in a 
Revisions folder in the backup destination. Users can configure how many versions of a file to maintain.
Shadow supports backups on local hard drives, USB/FireWire external hard drives, USB pen drives, NAS 
devices, and any drive with drive letter access.
Launching the utility is as easy as pressing one buttons. For more information refer to the NTI Shadow help
