Custom scripts

When defining a LiveClone Backup and DR Workflow that performs pre-scrubbing you can select from Optim privacy data masking or custom scripts.

For custom scripts, specify at least one pre- or post-processing script.

• Specify a pre-script as needed. The pre-script is used to configure the environment prior to mounting or unmounting the application. This script must reside in a folder named /act/scripts on the server that hosts the mounted image.
• In the corresponding Timeout in Seconds, specify the time that is needed for the script to complete.
• Specify a post-script as needed. The post-script used to perform an operation on the data after it is mounted or unmounted. This script must reside in a folder named /act/scripts on the server that hosts the mounted image.
• In the corresponding Timeout in Seconds, specify the time that is needed for the script to complete.

Backup and DR Workflow Pre and Post Scripts

Backup and DR Workflows mount and unmount backup images according to a schedule or on demand. In a Backup and DR Workflow you can call the following:

• A pre-script that runs before an image is mounted or unmounted
• A post-script that runs after an image is mounted or unmounted

The ability to run a script before and after data is mounted or unmounted allows you to do the following:

• Scrub for sensitive information
• Generate reports
• Warehouse data, especially when extracting, transforming, and loading—ETL—is required

Scripts must reside in a folder named /act/scripts on the server that hosts the mounted Backup and DR Workflow image.

Note: For Backup and DR Workflows that involve both a database and its logs, you must configure scripts in such as way that pre- and post-script operations are not applied to the database's logs. See Example Script for a script example that contains a command that skips a database's log.

Environment variables

Environment variables allow you to invoke commands that apply to specific jobs, job types, or applications. Environment variables are prefixed with ACT_. For example, an environment variable for a database could look like:

    [$ACT_APPNAME =="productiondb"]

or an environment variable for a mount operation could look like:

    [$ACT_JOBTYPE == "mount"]

The following is a list of common environment variables with sample values in parentheses.

• JOBNAME: The name of the job—for example, Job_0123456.
• APPID: The ID of the application—for example, 4186.
• APPNAME: Name of the application—for example, My-DB.
• HOSTNAME: The name of the host which is the target of this job—for example, Jupiter.
• SOURCEHOST: The name of the host that was the source for this application—for example, Saturn.
• JOBTYPE: A text version of the job class—for example, mount or unmount.
• PHASE: A text string that describes the job phase—for example, pre or post.
• TIMEOUT: Define the duration of the script, how long the script is allowed to run.
• OPTIONS: Policy options that apply to this job.

Example script

The following script example uses three environment variables:

• ACT_JOBTYPE. Identifies whether the job is a mount or unmount operation
• ACT_PHASE. Identifies whether the phase is either pre or post

• ACT_MULTI_END. Used only if both a database and its log are mounted. When this is true, the database is in a state where it can be accessed

  Note: The following example script is not meant to be used in a production environment, has not been tested, and is not warranted by Backup and DR Service.

  #!/bin/sh
  set +x
  echo "*** Running user script: Job - $ACT_JOBNAME Type - $ACT_JOBTYPE Phase - $ACT_PHASE***"
  
  #Use the first if clause to perform application specific operations during mount and in this example scrub-mount operation.
  
  #Use the second if clause to perform any application specific operation during unmount and in this example, #scrub-unmount operation.
  
  #if [[ $ACT_JOBTYPE == "mount" ]] || [[ $ACT_JOBTYPE == "scrub-mount" ]]; then
  if [[ $ACT_JOBTYPE == "unmount" ]] || [[ $ACT_JOBTYPE == "scrub-unmount" ]]; then
      echo "NO-OP for job type $ACT_JOBTYPE"
      exit 0
  fi
  
  #Use the first if clause to perform application specific operations during the pre phase.
  
  #Use the second if clause to perform application specific operations during the post phase.
  
  #if [[ $ACT_PHASE == "post" ]]; then
  if [[ $ACT_PHASE == "pre" ]]; then
      echo "NO-OP for phase $ACT_PHASE"
      exit 0
  fi
  
  #For multi-phase jobs (database and logs) check if the database has been mounted and the logs applied then #skip logs.
  
  #If the operation needs to be performed in phases other than the last phase, modify the clause.
  
  if [[ -z "$ACT_MULTI_END" ]] && [[ $ACT_MULTI_END != "true" ]]; then
      echo "NO-OP for multi-phase operation"
      exit 0
  fi
  cd /act/scripts
  
  echo "**** Running application specific logic: Job - $ACT_JOBNAME Type - $ACT_JOBTYPE Phase - $ACT_PHASE *"
  
  Any application specific commands will go here
  
  echo "** Finished running application specific logic : Job - $ACT_JOBNAME Type - $ACT_JOBTYPE Phase - $ACT_PHASE*"
  exit $?
