so setting it to a higher value (like 10 seconds) doesn’t

impact its performance, however it will allow SnapBack

to get the required window.

2. If the above is not possible, you can have SnapBack

execute external program files as predetermined points

to start, stop, or pause applications.

Three files are used to provide this capability:

PREBACK.BAT which is executed before the initializing

of SnapBack has taken place. This file can be used to stop

applications, make Win32 API calls to close databases,

etc.

POSTINIT.BAT which is executed as soon as the

quiescent window is achieved, but before the backup

starts. This can be used to restart mission critical apps,

such as email servers, databases, etc.

Win NTWin NT

POSTBACK.BAT which is executed after the backup has

occurred, either successfully or not. This can be used to

restart applications that do not matter in the normal course

of the backup. This can be defraggers, etc.

To stop a service, you can use "Net stop". To start a

service, you can use "Net start". The files can be

programmed to do anything except to provide screen output

and/or user input, as there are no users to see or respond to

prompts.

The files are executed in the "LocalSystem" account, which

means the programs have access to all system resources on

that computer (no network access is allowed). You can

specify which user you want the programs to run under via

the registry.

Under key:

HKEY_LOCAL_MACHINE\System\CurrentControlSet\

Services\SnapBack Backup Engine
