Pre/Post data capture commands

The option enables you to define the commands to be automatically executed before and after data capture (that is, taking the data snapshot). Data capture is performed at the beginning of the backup procedure.

The following scheme illustrates when the pre/post data capture commands are executed.

	<----------------------------        Backup        ---------------------------->
Pre-backup command	Pre-data capture command	Data capture	Post-data capture command		Post-backup command

If the Volume Shadow Copy Service option is enabled, the commands' execution and the Microsoft VSS actions will be sequenced as follows:

"Before data capture” commands -> VSS Suspend -> Data capture -> VSS Resume -> "After data capture" commands.

By using the pre/post data capture commands, you can suspend and resume a database or application that is not compatible with VSS. Because the data capture takes seconds, the database or application idle time will be minimal.
