DESCRIPTION

You can use the LifeCycle command with the Default and Show options to display the default values for each of the LifeCycle parameters and the current parameter values, respectively.

You can use the LifeCycle Tune command to adjust the following parameters:

  • CLEANUP_SESSION_INTERVAL - To define how often the deleted life cycle policies should be cleaned up.

  • DUPLICATION_GROUP_CRITERIA - To define how batches are created.

  • IMAGE_EXTENDED_RETRY_PERIOD - To define how long NetBackup waits before an image copy is added to the next duplication job.

  • JOB_SUBMISSION_INTERVAL - Set the frequency of job submission for all operations.

  • MAX_SIZE_PER_DUPLICATION_JOB - To define how large the batch of images is allowed to grow.

  • MAX_TIME_TIL_FORCE_SMALL_DUPLICATION_JOB - To define how old any image in the group can become before the batch is submitted as a duplication job.

  • MIN_SIZE_PER_DUPLICATION_JOB - To define the size that the batch of images should reach before one duplication job is run for the entire batch.

  • REPLICA_METADATA_CLEANUP_TIMER - Set the number of days after which the Import Manager stops trying to import the image.

  • TAPE_RESOURCE_MULTIPLIER - Set the multiplier for the number of concurrently active duplication jobs that can access a single storage unit.

  • VERSION_CLEANUP_DELAY - To define how much time must pass since an inactive version was the active version.

OPTIONS

LifeCycle Defaults

Use this command to show the default values of each of the parameters.

LifeCycle Show

Use this command to show the current values of each of the parameters.

LifeCycle Tune CLEANUP_SESSION_INTERVAL Interval Unit

How often the deleted life cycle policies should be cleaned up. The Interval variable denotes the time interval after which the policies are to be cleaned. The Unit variable is used to provide the unit for the time interval in Seconds, Minutes, Hours, Days, Weeks, Months, or Years. You cannot enter a size that is less than 10 Seconds, when the unit is set as Second(s). The default value is 24 hours.

DUPLICATION_GROUP_CRITERIA Criteria

Use this command to define how batches are created. Batches are created based on the life cycle policy name or the duplication job priority. You enter either PolicyName or JobPriority

LifeCycle Tune IMAGE_EXTENDED_RETRY_PERIOD Interval Unit

How long NetBackup waits before an image copy is added to the next duplication job. The Unit variable is used to provide the unit for the time interval in Seconds, Minutes, Hours, Days, Weeks, Months, or Years. You cannot enter a size that is less than 10 Seconds, when the unit is set as Second(s). The default value is 2 hours.

LifeCycle Tune JOB_SUBMISSION_INTERVAL Interval Unit

Use this command to set the frequency of job submission for all operations. The Interval variable is defined in minutes. The Unit variable is used to provide the unit for the time interval in Seconds, Minutes, Hours, Days, Weeks, Months, or Years. You cannot enter a size that is less than 10 Seconds, when the unit is set as Second(s). The maximum interval for this variable is not identified.

LifeCycle Tune MAX_SIZE_PER_DUPLICATION_JOB Size Unit

How large the batch of images is allowed to grow. The Size variable is the size of the duplication job. The Unit variable is used to provide the unit for the time interval in Bytes, KB, MB, GB, TB, or PB. If you select the unit as Bytes, you cannot enter a size that is less than 1024 Bytes. The maximum value is 2147483647.

LifeCycle Tune MIN_SIZE_PER_DUPLICATION_JOB Size Unit

The size that the batch of images should reach before one duplication job is run for the entire batch. The Size variable denotes the size of the duplication job. The Unit variable denotes unit of size in Bytes, KB, MB, GB, TB, or PB. You cannot enter a size that is less than 1024 Bytes, when the unit is set as Bytes.

LifeCycle Tune REPLICA_METADATA_CLEANUP_TIMER Time

Use this command to set the number of days after which the Import Manager stops trying to import the image. The Time variable is defined in the number of days. You turn this parameter off if you enter a value of zero.

LifeCycle Tune TAPE_RESOURCE_MULTIPLIER Value

Use this command to set the multiplier for the number of concurrently active duplication jobs that can access a single storage unit. The Value variable contains the multiplier value that is between 1 to 2147483647. The default value is 2.

LifeCycle Tune VERSION_CLEANUP_DELAY Time Unit

How much time must pass since an inactive version was the active version. The Time variable denotes the time that must pass since an inactive version was the active version. The Unit variable is used to provide the unit for the time interval in Seconds, Minutes, Hours, Days, Weeks, Months, or Years. You cannot enter a size that is less than 10 Seconds, when the unit is set as Second(s). The default value is 14 hours.

Examples

The Defaults command shows the values of each of the LifeCycle parameters:

LifeCycle > Defaults
CLEANUP_SESSION_INTERVAL                 : 24 hours
DUPLICATION_GROUP_CRITERIA               : 1
IMAGE_EXTENDED_RETRY_PERIOD              : 2 hours
JOB_SUBMISSION_INTERVAL                  : 5 minutes
MAX_SIZE_PER_DUPLICATION_JOB             : 100 GB
MAX_TIME_TIL_FORCE_SMALL_DUPLICATION_JOB : 30 minutes
MIN_SIZE_PER_DUPLICATION_JOB             : 8 GB
REPLICA_METADATA_CLEANUP_TIMER           : 0 hours
TAPE_RESOURCE_MULTIPLIER                 : 2
VERSION_CLEANUP_DELAY                    : 14 days
