Built-in scheduling of backups
Backups can be started either automatically at scheduled times or manually by clicking a button.
Stop & Resume:
Backups can be stopped and resumed at any time. This is handy when the computer needs to be shut down, for example.

Versioning & Incremental Backups

Multiple old versions of your backup data can be kept
Versions are stored very efficiently
Only the changes between two backups are actually stored
Reverse Incremental storage for image-based backups (block level)
A special kind of incremental storage that avoids the drawbacks of normal incremental or differential backup algorithms.
Special incremental storage for file-based backups (block level)
The optimized incremental algorithm is very efficient for storing file-based backup data.


Backups can be compressed with the following algorithms:
LZMA (multiple compression levels)
Small File Optimization
Through smart uses of compression the software can achieve high compression rates, even with many small files.

Password Protection & Encryption

AES 256 Bit
