Continuously monitor folders for changes and update their backup copies immediately after the originals are modified. Or run backups at fixed time intervals.
Reduce the amount of data being transferred by copying modified parts of the files only. This speeds up the backup, in many cases - dramatically.
Copy not only the file data, but also the attributes, timestamps, NTFS security and ownership information.
Rest assured that an issue with a specific file will not preclude the rest of the backup from completing. The program differentiates between file-specific and global errors and handles them differently.
Minimize the run-time bloat. The program is small, light and closely integrated with an operating system.
Specify an exact set of files to be backed up using simple and flexible folder and file filtering system.
The program is designed around the simplicity of a day to day use. Clear status indication, concise error reporting and a one-click access to detailed status information when you need it. Eliminate unnecessary spin-ups of idle hard drives by not touching the destination when there are no local changes. Keep your copy of the program updated to the latest version with automatic or manual software updates. Run the program under regular user accounts as it installs no drivers or services, requires no reboots and, with an exception of shadow copying, needs no administrative privileges.
