4.7.18.2 Post-backup command
To specify a command/executable file to be executed after the backup is completed
1. In the Command field, type a command or browse to a batch file.
2. In the Working directory field, specify a path to a directory where the command/batch file will
be executed.
3. In the Arguments field, specify the command execution arguments, if required.
4. Select the Fail the task if the command execution fails check box if successful execution of the
command is critical for you. The command is considered failed if its exit code is not equal to zero.
If the command execution fails, the program will remove the resulting TIB file and temporary files
if possible, and the task run result will be set to Failed.
When the check box is not selected, the command execution result does not affect the task
execution failure or success. You can track the command execution result by exploring the log or
the errors and warnings displayed in the Log view.
5. Click Test Command to check if the command is correct.
4.7.19 Pre/Post data capture commands
This option is effective for both Windows and Linux operating systems.
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 by Acronis Backup 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 (p. 128) 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.
Using the pre/post data capture commands, you can suspend and resume a database or application
that is not compatible with VSS. As opposed to the Pre/Post commands (p. 120), the pre/post data
capture commands will be executed before and after the data capture process. This takes seconds.
The entire backup procedure may take much longer, depending on the amount of data to be backed
up. Therefore, the database or application idle time will be minimal.
To specify pre/post data capture commands
1. Enable pre/post data capture commands execution by checking the following options:

Execute before the data capture

Execute after the data capture
2. Do any of the following:

Click Edit to specify a new command or a batch file

Select the existing command or the batch file from the drop-down list
3. Click OK.
