Media Management Configuration: Data Aging

Use this dialog box to establish data aging parameters.

Parameter Description
Allow administrators to lower job retention on WORM copies Definition: Specifies that user that are members of master user group can now modify the retention period of Retained jobs associated with WORM copy.

Default Value: 0

Range: 0 (disabled) or 1 (enabled)

Allow CI pruning of backup jobs which aged from all copies Definition: Specifies that the data aging must prune the content index from the Search Engine even if the backup data is spread across tape and magnetic libraries.

Default Value: 0

Range: 0 (disabled) or 1 (enabled)

Consider inactive copy for Auxiliary Copy check by Data Aging Definition: Specifies that the source copy data will not be pruned if it is not copied on the inactive copy.

Default Value: 1

Range: 0 (disabled) or 1 (enabled)

Usage: If a secondary copy is created for a storage policy, all source copy data required by that destination copy – either synchronous (all data) or selective must be retained until a successful auxiliary copy operation has been completed. This action may not be desired if (a) you are creating secondary copies now with the intention of them holding data at a later point-in-time. Or (b) you forgot to delete a secondary copy and the data movement is no longer required. In either case, you can set the copy status to inactive and set this parameter to 0 (disabled), enabling subsequent Data Aging operation to prune all data being retained solely for pending auxiliary copy operations to now inactive copies.

Days to consider for pending logical pruning for Deduplication pruning threshold event Definition: This parameter allows you to generate an event message when the number of deleted records are older than the 7 days and meets the threshold value specified in the Max number of records pending logical pruning for Deduplication pruning threshold event parameter.

Default Value: 7 days

Range: 1 – 100 days

Usage: For example, you have set the number of days to four on Friday (01-20-2013) and the threshold value in the Max number of records pending logical pruning for Deduplication pruning threshold event parameter is set to 10,000. If the number of deleted records older than past Monday (01-16-2013) is greater than the threshold value that is 10,000, then an event message is generated. Once the value is set the check is performed every day to verify both the criteria.

Days to keep Dash Copy Job Chunk History Definition: Specifies the number of days for which chunk's metadata is stored in main database table which is used to identify which jobs were copied during the auxiliary copy operation with Use Scalable Resource Allocation check box is selected. After the defined number of days, the chunk's metadata is transferred to the history table.

Default Value: 7

Range: 0 to 30

Days to keep Data Management and Collection Job Histories Definition: Specifies the number of days the data management and data collection jobs histories are preserved.

Default Value: 90 days

Range: 0 to 5000

Usage: Retaining job history for longer or shorter periods may be required for compliance, auditing, or other reasons.

Days to keep invalid chunks Definition: Specify the number of days that invalid chunks are preserved.

Default Value: 3

Range: 3 to 10 (Values set to less than 3 are reset to 3).

Usage: An invalid chunk is one where the job was interrupted and the chunk needed to be rewritten for integrity purposes. Data from these invalid chunks are usually unrecoverable, but could provide some data recovery in a DR situation where no other valid chunks exist.

Days to keep job options for a completed job Definition: Specifies the number of days to retain the job option information (such as job resource history, Job failure reason, miscellaneous information and so on) in the CommServe database for a completed job.

Default Value: 30 days

Range: 7 to 999,999,999 days

Usage: Retaining job options for longer or shorter periods may be required for compliance, auditing, or other reasons.

Days to keep job status change history for GRC Definition: Specifies the number of days to retain the job status history performed in GRC.

Default Value: 90 days

Range: 7 to 180

Days to keep jobs of de-configured clients Definition: Specifies the number of days to retain the jobs of deconfigured clients.

Note:

  • Data Aging will honor the highest of storage policy copy days retention or the number of days specified in this parameter.
  • If you want to use only days retention and ignore the cycle retention, set Ignore Cycles Retention on De-Configured Clients parameters as 0.
  • Spool copy ignores this parameter and continues to honor the spool retention (zero days and zero cycle).

Default Value: 0

Range: -1  to 11000 days. (-1 is for infinite retention)

Days to keep Library Histories Definition: Specifies the number of days to retain the information about disk usage on magnetic libraries, before it is pruned. Default value is set at 14.

Default Value: 14 days

Range: 7 to 180 days

Usage: Retaining disk usage for longer or shorter periods may be required for compliance, auditing or other reasons.

Days to keep Replication Backup Job Histories Definition: Specifies the number of days to retain the replication backup job histories. The default value is set to 90 days.

Default Value: 90

Range: 7 to 999,999,999 days

Usage: Retaining job history for longer or shorter periods may be required for compliance, auditing or other reasons.

Days to keep the archiver restore job histories Definition: Specifies the number of days to retain the archiver restore job history data before it is pruned. Note that when the value is set to 0, the retention is set to infinite and not zero days.

This setting is applicable only for Exchange Compliance Archiver. All other archiver restore job histories will be pruned based on the Days to keep the backup job histories parameter.

Default Value: 0

Range: 0 to 5000

Usage: Retaining job history for longer or shorter periods may be required for compliance, auditing, or other reasons.

Days to keep the failed/killed backup job and other job histories Definition: Specifies the number of days to retain backup job history data before it is pruned. This applies to: Auxiliary Copy jobs, Stub Recall jobs, failed jobs, killed jobs, jobs that failed to start, replication backup jobs, and all restore jobs except for archive restore job history.

Note: For auxiliary copy, stub recall, replication backup, and restore job history, this parameter applies to job start time.

Default Value: 90

Range: 0 to 5000

Usage: Retaining job history for longer or shorter periods may be required for compliance, auditing, or other reasons. Before reducing this number you should consider that valid chunks associated with failed/killed jobs can be restored using the Restore by Job task.

Days to keep the list of migrated foreign jobs to be pruned after processing them Definition: Specifies the number of days to maintain the history of the migrated foreign jobs.

Default Value: 7 days

Range: 3 to 30

Usage: This parameter is useful to retain the history of migrated foreign jobs for specified number of days. Once the specified number of days is reached the history of the migrated jobs gets pruned.

Days to keep the Site Replication job histories Definition: Specifies the number of days to retain job history information for Live Sync operations after it is pruned.

Default Value: 30 days

Range: 0 - 5000 days

Usage: Specify fewer days to limit the size of storage required for job history, or additional days to keep job history available for longer (only for audit purposes).

Days to keep the successful backup job histories Definition: Specifies the number of days to retain successfully completed backup job history data after it is pruned.

Default Value: 7

Range: 0 to 5000

Usage: Retaining job history for longer or shorter periods may be required for compliance, auditing, or other reasons. Successful backup job history is retained for as long as the data is restorable plus the number of days specified here. Increasing this number might be prudent if you are doing trend analysis on information contained within the backup job histories.

Days to retain the jobs when cycles are ignored and retention days on copy is 0 Definition: Specifies the number of days to retain a job when its cycles are ignored and retention days are 0.

This parameter will take effect when days retention on a storage policy copy and Days to keep jobs of de-configured clients parameter is set to 0.

Default Value: 30

Range: 1 to 999

Usage: This is to protect you from inadvertently deleting data by incorrectly setting a storage policy copy’s retention criteria.

Delete deconfigured clients that have no protected data Definition: During data aging job, if there are clients or restore-only clients that are in deconfigured state, those clients will be deleted if there are no jobs associated with them.

Default Value: 0

Range: 0 (No) or 1 (Yes)

Usage: By default, the value is set to 0 which means that clients or restore-only clients that are deconfigured will not be deleted. Set value to 1 to delete the clients or restore-only clients that are in deconfigured state, if there are no jobs associated with them.

Notes:

  • For tape library, the deconfigured clients are deleted only when all the media associated with the tape library are recycled.
  • Auto discovered Virtual Server clients will not be deleted.
Disable jobs for Auxiliary Copy that met its retention Definition: When this option is enabled, jobs that are not available on the destination copy that is, jobs with status To Be Copied or Partial are marked disabled for Auxiliary Copy, when those jobs meet the retention criteria defined on that destination copy.

Applies to all storage policies in the CommCell.

Default Value: 1

Range: 0 (disable) or 1 (enabled)

Usage: Use this option to reduce the overhead on Auxiliary Copy job. For more information, see Disabling Jobs for an Auxiliary Copy that meets the Retention Criteria.

Disable RMAN External Pruning Definition: You can use this configuration parameter to disable the deletion of the archive files when you use external RMAN scripts to clean up the backup pieces.

Default Value:  1

Range: 0 or 1

Usage: The RMAN external pruning feature is disable when this parameter is set to 1.

Enable Dataset and Dataset Member Pruning Definition: You can use this configuration parameter to enable dataset and dataset member pruning or subscription and subscription context pruning on OnCommand Unified Manager (OCUM).

Default Value:  0

Range: 0 or 1

Usage: Set this parameter to 1 to enable automatic deletion of OCUM dataset or subscription context and dataset or subscription context members after the corresponding subclient or subclient content is deleted or the subclient reassociated and all its jobs are pruned. The Enable Dataset and Dataset Pruning parameter set to 1 is a prerequisite for the Delete NetApp secondary vault/mirror volumes for aged members parameter, to enable the deletion of secondary volumes for aged dataset members for cases in which there is subclient deletion or reassociation, or subclient member deletion or reassociation.

Honor Extended Retention Rules for Oracle/RAC/SAP regular Full Jobs Definition: Allow Oracle, Oracle RAC and SAP Oracle full backup jobs to be eligible for selective copy and extended retention rules.

Default Value: 1 for new V11 installs, 0 for upgrades to V11

Range: 0 (No) or 1 (Yes)

When the value is set to '1', full backups that your perform from the CommCell Console for Oracle, Oracle RAC and SAP Oracle databases, are eligible for selective copy and extended retention rules. When the value is set to '0',  full backups that your perform from the CommCell Console for Oracle, Oracle RAC and SAP Oracle databases are not eligible for selective copy and extended retention rules.

Usage: By default, on installs full backups that your perform from the CommCell Console for Oracle, Oracle RAC and SAP Oracle databases are eligible for selective copy and extended retention rules.

Honor SQL Chaining for Full jobs on Selective copy Definition: Specifies whether or not to honor SQL chaining for full jobs on a selective copy.

Default Value: 1

Range: 0 (No) or 1 (Yes)

When the value is set to '1', full jobs on selective copy retain logs that are chained. Full backups are not aged.

When the value is set to '0', full jobs on selective copy are retained by basic retention criteria. Full backups do not retain the logs that are chained with SQL_CHAIN or SQL_LOG_RULE.

Usage: By default, the value is set to 1. Full jobs on selective copy retain logs that are chained. Full backups are not aged.

Ignore Completed With Errors job option for Extended Retention calculations Definition: Specifies whether or not to ignore the Completed With Errors job option for Extended Retention calculations.

Default Value: 0

Range: 0 (No) or 1 (Yes)

When the value is set to '1', the current value set for the Completed with Errors job in the agents' database is ignored for extended retention calculations. When the value is set to '0', the current value set for the Completed with Errors job is honored for extended retention calculations.

Usage: Administrator may hold extended retention Jobs to a higher standard than those used to determine normal media/retention cycle.

Ignore Compliance Policy Check For Job Data Aging Definition: Specifies whether or not to ignore the Compliance Policy Check for Job Data Aging.

Default Value: 0

Range: 0 (No) or 1 (Yes)

Usage: Applies to the Automated Content Classification Policy. During a data aging operation, if a particular job is qualified to be processed by an Automated Content Classification Policy, the data will be retained even though it is eligible to be aged, until it is acted upon by the Automated Content Classification Policy. Setting this value to 1 will allow data aging to prune the job regardless.

Ignore Cycles Retention On De-Configured Clients Definition: Specifies whether or not to ignore the defined retention cycle rules for data associated with deconfigured clients.

Default Value: 0

Range: 0 (No) or 1 (Yes)

Usage: Without cycle retention (parameter value set to 1), only days are used to retain data on deconfigured clients. Ultimately, all data will be pruned in this case. The default keeps at least the last cycle of the data.

Note: The OnePass feature ignore the Ignore Cycles Retention on De-Configured Clients parameter.

Ignore Reference Copy Rule to retain jobs on source subclients Definition: Specifies the retention of jobs on source subclients for the reference copy requirements

Default Value: 0

Range: 0 (No) or 1 (Yes)

Usage: This parameter specifies the retention of jobs on the source subclients when the reference copy subclients are configured for them. When the parameter value is set to 0, the jobs are retained on the source subclient until reference copy is done. When the value is set to 1, the jobs are not retained on the source subclient for reference copy requirements.

Max number of records pending logical pruning for Deduplication pruning threshold event Definition: Specifies the threshold value of the deleted records that are not pruned from the disk.

Default Value: 10000

Range: 5000 – 1000000

Usage: For example, you have set the threshold value to 10,000 records, and the number of days in the Days to consider for pending logical pruning for Deduplication pruning threshold event parameter is set to four on Friday (01-20-2013). If the number of deleted records older than past Monday (01-16-2013) is greater than the threshold value that is 10,000, then an Event message is generated. Once the value is set the check is performed every day to verify both the criteria.

Maximum job entries to use for calculation of media retention expire time Definition: Every few minutes the media retention time is recalculated for media that is written to in that time. This entry specifies how many entries are processed.

Default Value: 5000

Range: 0 (all) to 9,999,999

Number of disk folders to process in a single Data Aging request Definition: Specifies the number of disk folders to be processed to a MediaAgent for physical pruning during a pruning cycle

Default Value: 1000

Range: 1 to 5000

Usage: The pruning of aged jobs is initiated periodically by the CommServe. In this parameter, you can specify the maximum number of disk folders to be processed to a MediaAgent for physical pruning during a pruning cycle. This parameter is considered for batch processing when the number of disk folders exceed the value specified..

Prune All Database Agent Logs Only By Days Retention Rule Definition: Specifies whether or not to ignore the log rule for all Database agents.

Default Value: 0

Range: 0 (No) or 1 (Yes)

Usage: Database logs retention can be linked to the retention of the related database file. Therefore, if you retain a full database backup, related transactional logs will also be retained until the full database backup is pruned regardless of any lesser retention setting for the logs.

  • When the value is set to 0 the log rule is honored.
  • When the value is set to 1 the log rule is ignored and only days to retain logs is used. This might be riskier for point-in-time recovery.
Prune the jobs on tape media when the retention criteria is met Definition: Specifies the pruning of jobs on tape media completely when the retention criteria is met so that the jobs cannot be unaged or restored in future

Default Value: 0

Range: 0 (No) or 1 (Yes)

Retain DDB Backups of sealed stores Definition: Specifies whether or not to retain the DDB backup of a sealed DDB.

When the value is set as 1 the last DDB backup job that was backed up before sealing the DDB is kept. Set value as 0 to not retain the DDB backup job.

Default Value: 0

Range: 0 (No) or 1 (Yes)
