What Are Data Engrams?
Have you ever updated a document and then later wanted to go back to a previous version of that document? This is basically what Data Engrams™ allow you to do. They work like revision history which allows you to go back to previous versions of your data. But what are Data Engrams?
Data Engrams basically are copies of your files at different points in time. In order to create Data Engrams a technology called Mirror Shielding™ is used. Mirror Shielding protects your data by preventing it from being directly modified and instead stores the changes in an overlay. (See How Does Mirror Shielding Work? for more details.) Before any change on the overlay can be committed to disk the current disk contents can be saved off to a separate location and stored as a Data Engram.
How to Use Data Engrams
All editions of Data Sentinel allow you use the revision history feature. However, only files in a protected folder can be restored to a different revision.
To restore a file:
- Start Windows Explorer and browse to the file you wish to restore.
- Right-click on the file and select ‘Properties’ from the menu.
- Open the ‘NeuShield’ tab.
- Select the revision of the file you wish to restore, and press ‘Restore’.
