Erase Backup or Archived Data - How Do I

Table of Contents

Overview

Backed up or archived data permanently consumes space on the secondary storage medium that you write it to. You can reclaim this space by deleting the data from the storage medium. The SnapProtect software can delete this data by removing it from a single backup instance, or from all backup instances.

Agents that Support Erasing Data

These agents support erasing backed up or archived data:

Erasing Data by Browsing

This method supports erasing data from a backup or archive. When backed up or archived data is erased by browsing, it is no longer restorable, and stub recall attempts are blocked.

Before You Begin

  • Important: Erasing data by this method erases it from all occurrences, including across backup and archive sets that are configured under a client. If a data item exists in multiple backup or achive sets, erasing that item in one of them erases it in all of them. Be sure this is the result you want.
  • In the Erase Backup/Archived Data dialog box, only the data objects that you add to the Selected Path box are erased during the erase data operation. The additional options that you select for the browse operation only filter the data that is visible for browsing and are not applied to the data that will be erased.

Procedure

After acquiring a license for this feature, use the CommCell Console to browse and select objects to erase as follows:

Step 1: Assign a Filter Storage Policy for Erase Data by Browsing.

  1. From the CommCell Browser, right-click the appropriate agent icon, then click Properties.
  2. From the Storage Device tab of the agent Properties dialog box, select a filter storage policy from the Filter Storage Policy list.
  3. Click OK.

Step 2: Allow Erase Data in Storage Policy.

  1. From the CommCell Browser, right-click the storage policy you want to allow for the erasing of data, then click Properties.
  2. From the (General) tab of the Storage Policy Properties dialog box, select the Allow Erase Data check box.
  3. Click OK.

Step 3: Run Erase Data by Browsing Job.

  1. From the CommCell Browser, right-click the agent or instance that contains the data that you want to erase, select All Tasks, then click Erase Data By Browsing.
  2. You are warned that the data will be permanently removed. Click Yes to continue.
  3. From the Erase Backup/Archived Data dialog box, perform one of the following tasks as appropriate for your agent:
    • Click Add, then specify the path of a data object that you want to erase, and click OK.
    • Click Browse, then select a browse time range and any advanced browse options, and click OK. From the browse selection window, select the data objects that you want to erase, and click OK.

      Note: The advanced browsing options and filters only apply to the browse operation and are not applied to the erase data operation.

  4. Optionally, you can click Add Alert to configure an alert for this job.
  5. Click Schedule if you would like to schedule this job, otherwise it will run immediately by default.
  6. If you want to run the job immediately, click OK and the Erase Data by Browsing job will begin. When the job is done, Job Controller displays Completed.
  7. If you selected Schedule, from the Schedule Details (Schedule Details) dialog box, create a schedule for this operation. Click OK to continue. Your Erase Data by Browsing operation will execute according to the specified schedule. See Create a Job Schedule for more information.

Erasing Data by Stubs

This method permanently erases stubs that have been deleted in a specified location. Stubs contain information about the archived data to facilitate end-users with non-browse recovery operations (i.e., stub recalls) from third-party applications. Use this method if you want to to permanently erase stubs once they are deleted and if they pertain to the content of just one subclient. When stubs are deleted in a specified location and an Erase Data job is run, stub recalls are blocked.

After acquiring an license for this feature, use the following procedure to permanently erase stubs:

Step 1: Associate a Subclient to a Storage Policy.

  1. From the CommCell Browser, right-click the subclient whose associated storage policy you want to change, then click Properties from the shortcut menu.
  2. Click the Storage Device tab of the Subclient Properties dialog box.
  3. From the Storage Policy list of the Data Storage Policy tab, select a data storage policy to associate with this subclient. If necessary, click the Create Storage Policy button to create a new storage policy to which the subclient can then be associated.
  4. From the Changing a Storage Policy dialog box select the next type of backup operation. Click OK.
  5. If applicable for your agent, you can change the number of data streams from the Number of Data/Database Backup Streams field.
  6. If applicable for your agent, click the Log Storage Policy tab and select a storage policy to associate with this transaction log subclient from the Transaction Log Storage Policy list. Also, you can set the Number of Transaction Log Backup Streams from this tab.
  7. Click OK to save your changes and close the Subclient Properties Storage Device tab.

Step 2: Allow Erase Data in Storage Policy.

  1. From the CommCell Browser, right-click the storage policy you want to allow for the erasing of data, then click Properties.
  2. From the (General) tab of the Storage Policy Properties dialog box, select the Allow Erase Data check box.
  3. Click OK.

Step 3: Specify Deletion Location. 

  1. From the CommCell Browser, right-click the appropriate agent icon, then click Properties.
  2. From the General tab of the Agent Properties dialog box, select the Erase archive data when stub is deleted option.
  3. In the text box, specify the location where if stubs are deleted from there, they will be collected in a file. This could be the entire computer (indicated by a \), a particular drive (C:\), a particular folder (C:\deleted_data), or a UNC path (\\filer\directory).  Multiple locations could also be specified, separated by the ; delimeter.

    The path that is configured here will be applicable for all instances of the File Archiver for Windows Agent.:

    • For Local File System instances, a folder can be created to contain the stubs to be hard-deleted (SHIFT_DELETE). This folder would then be part of the path that is specified (e.g., (C:\deleted_data).This would alleviate specifying entire volumes. From the volumes, you can then move the stubs (cut+paste) to the specified deletion folder. To move stubs across volumes, you must use the GXHSMUtility tool.
    • For Celerra and FPolicy instances, a folder cannot be created to contain the stubs that are deleted. You can instead restrict the deletion to certain folders by specifying a subclient path or a path that is a parent to the subclient path.
    • The path that is configured here is only used when an Erase Data job is run.
    • If you delete stubs within the path that is specified and the subclient that includes the path is deleted, the data will not be erased.
    • For FPolicy instances, the user must either specify "\" or a specific deletion folder path. If the intended deletion folder path is \\<filer_name>\<volume_name>\<folder_name>, the deletion folder specification needs to be:
      \\<fully_qualified_filer_name>\ONTAP_ADMIN$\vol\<volume_name>\<folder_name>;\\<short_filer_ name>\ONTAP_ADMIN$\vol\<volume_name>\<folder_name>. Otherwise, the data will not be erased.

  4. Click OK.
  5. Recycle the services by restarting the DataArchiver Services from the Administrative Console. For step-by-step instructions, see Starting a Service on Windows. 

Step 4: Run Erase Data Job. 

  1. From the CommCell Browser, right-click a subclient of an appropriate Agent, click All Tasks > Erase Data.
  2. The Erase Data selected for deletion (General) dialog will appear allowing you to Schedule the job or Run Immediately.
  3. Optionally, you can click Add Alert to configure an alert for this job.
  4. Click the Job Retry tab to specify the job running time and the number of job retries. See Configuring Job Restart for Specific Jobs for more information.
  5. If you select Run Immediately, the Erase Data job will begin when you click OK, and you can track the progress in Job Controller.
  6. If you select Schedule the Schedule Details (Schedule Details) dialog box will open. This allows you to create a new schedule for this operation. After you are finished click OK to continue. Your Erase operation will execute according to the specified schedule. See Create a Job Schedule for more information.

Erasing Stubs from Outlook Add-In

Stubs can be erased from Outlook Add-in to erase stubs in a mailbox for the agents listed in Erase Backup/Archived Data - Support. Stubs contain information about the archived data to facilitate end-users with non-browse recovery operations (i.e., stub recalls) from Outlook or Outlook Web Access. After data is erased, any stub recall attempts will be blocked.

After acquiring an license for this feature, use the following procedure to permanently erase stubs:

Step 1: Configure the Outlook Add-In to allow end-users to add stubs to an Erase List.

  1. From Microsoft Outlook, select the stubs that you want to erase.
  2. Go to the Tools menu, click Mailbox Archiver >Add Selected Stubs to Erase List. If you want to erase all of the stubs in the folder click Add Stubs in Selected Folder to Erase List.
  3. A folder will appear in your folder list called Data Migrator. Under this folder another folder is created called Migrated Data to Be Erased.
  4. The stubs you have selected to be erased will be moved to the Migrated Data to Be Erased folder.

Step 2: Erase Stubs in Outlook.

  1. From the CommCell Browser, right-click the archive set of the Exchange Mailbox Archiver Agent or an individual subclient, click All Tasks > Erase Stubs.
  2. If you are erasing stubs for an archive set, you are asked to confirm that you want to erase all stubs marked for deletion on this client. Click Yes to continue.
