Study the shadowing - ч. 5

Usb security key software

	Without a shadow Data theft protection tool	DeviceLock	Zlock
One big file	125 c.	150 c. (+20%)	175 c. (+40%)
A number of small	760 c.	880 c. (+15%)	935 c. (+23%)

But we need to evaluate not only the data writing speed, but also the correctness of the shadow. When copying small files in the shadow copy all recorded correctly, and the file in 418 MB awaited surprise. So, in the local directory Zlock shadow copy of the file appears immediately at the start up, and its size increased simultaneously with the recording drive. In the case of DeviceLock this did not happen. Even after recording the stick system continued to work actively with the hard drive, and a copy of a fully formed only after 135 seconds after the end of the recording.
