Verify that no services or users are trying to access the intended GuardPoint. You can accomplish this by shutting down the database service, and then confirming that there are no users in the working directory.

...
...
...
Click Browse.
...
...

In the image below, the sample GuardPoint is: C:\Program Files\Microsoft SQL Server\MSSQL11.MSSQLSERVER\MSSQL\Log\
Select the desired GuardPoint.

...
field.

...
...
Click Ok.
...
...
...
Under Status, click the refresh button for the newly created GuardPoint.
...
You may need refresh several times.
...
...
...
...
On the Windows server where you are going to apply the GuardPoint, right-click on the PowerShell icon, and then
...
select Run
...
as Administrator.
...
Before you can run the encryption command, you must change into the directory where the Vormetric dataXform utility is located (C:\Program Files\).
...
Change the directory path where the utility is
...
located (C:\Program Files\Vometric\DataSecurityExpert\agent\vmd\bin).
...
The utility has a feature that allows you to scan the indended GuardPoint before you run the DataXform command, which can be useful to verify that the GuardPoint can be encrypted and also to offer an estimate on how long the encryption configuration will take.
...
The DataXform data command function is:
...
.\dataxform
...
••--deep_scan
...
••--gp <guard point path>
...
...
When you are in the DataXform utility path, you can run the DataXform command with various added arguments. The standard command is:
...
.\dataxform --rekey --
...
gp <directory path>
You can add the
...
.\dataxform --rekey
...
flag to read data with the clear key and write back in with the production key (encrypting the data in place).
You can
...
add --print_state
...
to retrieve a printout of how many files are going to be encrypted and periodic updates of how much data has been encrypted so far.
...
The command would
...
be .\dataxform --
...
rekey --print_stat --gp <directory path>
You can add the
...
--cleanup_on_success
...
flag to clean up the temporary files created during the DataXform process and are not necessarily needed in the future.
...
The command would be:
...
.\dataxform --
...
rekey --print_stat
...
--cleanup_on_success
...
—gp <direcotry path>
You can add
...
the --preserve_modified_
...
time flag to preserve the current time stamp of the files being encrypted, instead of changing the time stamp to when DataXform ran.
...
The command would be:
...
.\dataxform
...
••--rekey
...
••--print_stat --cleanup_on_success --
preserve_modified_time
...
--gp <directory>
After you enter the command,
...
press Enter.
...
If successful, you will see a text output similar to the screenshot below.
...
If unsuccessful, make sure there are two dashes before each flag and that the words are spelled correctly.
...
Assuming your data is already backed up, then
...
press y
...
to continue.
...
To remove the data transformation status files created earlier,
...
press y, and then
...
press Enter.
...
...
...
If you are logged out of the DSM console, after you login, click
...
the Hosts
...
tab, select the desired Host Name, and then
...
click Guard FS.
Mark the box next
...
to DataXForm_Policy.
Select
...
the Unguard button.
...
...
...
Click OK.
...
...
...
the Refresh
...
button.
...
...
...
When the GuardPoint disappears,
...
click Guard.
...
In the pop-up window, in
...
the Policy
...
drop-down menu, select your operational policy in learn mode. (In the screenshots below, the example
...
is R1_Testing_VMW12.
...
Expand the directory to the path, and then highlight the path you previously encrypted. (In the screenshots below, the example
...
is C:\Program Files\Microsoft SQL Server\MSSQL11.MSSQLSERVER\MSSQ\Log.
...
Click Ok.
...
...
the Refresh
...
button.
...
You may need to
...
click Refresh
...
several times before the GuardPoint turns green.
