Data Aging - Content Indexing

Table of Contents

Overview

Data Aging, as related to Content Indexing, is the process of removing data that has exceeded its defined retention from the Search Engine. Regardless of the data aging rules selected, individual objects within the Search Engine are not considered for data aging. Instead, all objects within a particular Storage Policy job are aged simultaneously upon the job exceeding the defined retention period for the selected aging method.

Options for data aging Content Indexed data include:

  • Retaining the index according to the data retention rule
  • Retaining the index for a number of days

For more information on retention of the back up data, refer Data Aging.

Retention Rules for Content Indexed Data

When you prune data based on data retention rules, the corresponding content index for the data also gets pruned from the search engine. However, if there are multiple copies of the data and you are pruning the data in only one of the copies, then the content index for that data does not get pruned automatically.

When you disable content indexing for a storage policy, a message appears that asks you if you want to permanently remove the content indexing ability for the storage policy. When you select Yes, the following changes occur:

  • New data associated to the storage policy will not be content indexed.
  • Existing data will be pruned based on the longest retention setting in the storage policy.
  • Data that has already been successfully content indexed can still be searched.

When you select No, the content indexes are retained and the content indexing feature is not disabled for the storage policy

Configure the retention criteria for the content index. By default the indexes are maintained as long as the data is maintained and automatically pruned when the data aging operation prunes the associated data.

Pruning Content Index Along with Data

Pruning the content indexes along with the data is the default behavior.

  1. From the CommCell Browser, navigate to Policies | Storage Policies.
  2. Right-click the <Storage Policy> that is enabled for Content Indexing, and then click Properties.

    The Storage Policy Properties dialog box appears.

  3. Click the Content Indexing tab.
  4. Click the Retention subtab.
  5. Click Retain the index as per data retention rule.
  6. Click OK.

Setting the Retention Days for Content Indexed Data

By default, the content indexes are pruned along with the data based on the data retention rules. In the procedure, you retain the content indexes for a specific number of days and prune them before the data is pruned.

  1. From the CommCell Browser, navigate to Policies | Storage Policies.
  2. Right-click the <Storage Policy> that is enabled for Content Indexing, and then click Properties.

    The Storage Policy Properties dialog box appears.

  3. Click the Content Indexing tab.
  4. Click the Retention subtab.
  5. Click Retain for n Days, and then specify the number of days that the content index will be retained from the start of the backup job.

    If the specified number of days is greater than the retention days set for the backup job, then the index is pruned along with the backed up data.

  6. Click OK.

Pruning Content Index for Backup Data on Tape and Magnetic Libraries

If the backup data is spread across tape and magnetic libraries, then by default data aging will not prune the content index from the Search Engine. If you want to enable pruning of content indexing data from the Search Engine in this case, perform the following configuration:

  1. In the CommCell Console ribbon, click the Storage Tab and then click Media Management.
  2. Click the Data Aging tab.
  3. Click the value of Allow CI pruning of backup jobs which aged from all copies and set the value to 1.
  4. Click OK.
  5. Restart the Media Manager service on the CommServe host.
  6. Wait twenty-four hours for the content index to be pruned from the Search Engine.

Deleting the Content Index of a Specific Backup Job

You can delete the content indexes for a job that was previously content indexed and prevent the job from being content indexed further. Once the content indexes are deleted, the Content Index Status for the specific job is changed to Not Picked (that is, the next content indexing operation is not include this job for content indexing).

  1. From the CommCell Browser, navigate to Policies | Storage Policies.
  2. Right-click the <Storage Policy> that is used during the Content Index Engine installation, and then click View | Jobs.
  3. Clear the Specify Time Range check box in the Job Filter for Storage Policy dialog box.

    By default, the jobs that were initiated in the past 24 hours appear. If you clear the Specify Time Range check box, all of the jobs that are associated with the copy appear.

    A list of jobs that are associated with the copy appears in the right pane of the CommCell browser.
  4. Right-click the job, and then select Delete Content Indexing Job.
  5. Click OK.
