Minimum size per duplication job | The smallest batch size that can run as a single duplication job. The job does not run until enough images accumulate to reach this minimum batch size or until the Force interval for small jobs time is reached. Minimum: 1 kilobyte; no maximum size. Default: 8 gigabytes. Configuration option default: SLP.MIN_SIZE_PER_DUPLICATION_JOB = 8 GB |
Maximum size per duplication job | The largest batch size that can run as a single duplication job. Minimum: 1 kilobyte; no maximum size. Default: 100 gigabytes. Configuration entry default: SLP.MAX_SIZE_PER_DUPLICATION_JOB = 100 GB |
Maximum size per A.I.R. replication job | The largest batch size that can run as a single job for Auto Image Replication. Minimum: 1 kilobyte; no maximum size. Default: 100 gigabytes. Configuration entry default: SLP.MAX_SIZE_PER_BACKUP_REPLICATION_JOB = 100 GB |
Maximum images per snapshot replication job | The largest number of images in a single batch that can run as a single job. Default: 50 images, with no minimum number or maximum number. Use this parameter with the Limit I/O streams disk pool option which limits the number of jobs that can run concurrently to each volume in the disk pool. Configuration entry default: SLP.MAX_IMAGES_PER_SNAPSHOT_REPLICATION_JOB = 50 |
Minimum images per A.I.R. Import job | The fewest number of images in a single batch that can run as an Auto Image Replication import job. The job does not run until either the minimum size is reached or the Force interval for small jobs time is reached. Minimum: 1 image; no maximum number of images. Default: 1 image. Configuration entry default: SLP.MIN_IMAGES_PER_IMPORT_JOB = 1 |
Maximum images per A.I.R. Import job | The largest number of images in a single batch that can run as an Auto Image Replication import job. Minimum: 1 job; no maximum number of images. Default: 250 images. Configuration entry default: SLP.MAX_IMAGES_PER_IMPORT_JOB = 250 |
Force interval for small jobs | The age that the oldest image in a batch must reach after which the batch is submitted as a duplication job. This value prevents many small duplication jobs from running at one time or running too frequently. It also prevents NetBackup from waiting too long before it submits a small job. Default: 30 minutes, with no minimum number or maximum number. Configuration entry default: SLP.MAX_TIME_TIL_FORCE_SMALL_DUPLICATION_JOB = 30 MINUTES |
Job submission interval | Indicates the frequency of the job submission for all operations. No minimum interval or maximum interval. Default: 5 minutes. By default, all jobs are processed before more jobs are submitted. Increase this interval to allow NetBackup to submit more jobs before all jobs are processed. Set the interval when the list of available images is scanned for those that can be batched together and jobs submitted. A shorter interval allows for a better response to changing system workloads at the cost of increased processing.
Configuration entry default: SLP.JOB_SUBMISSION_INTERVAL = 5 MINUTES |
Image processing interval | The number of minutes between image-processing sessions. Set the interval when newly created images are recognized and set up for SLP processing. Default: 5 minutes. Configuration entry default: SLP.IMAGE_PROCESSING_INTERVAL = 5 MINUTES |
Cleanup interval | The time between when a job finishes and before NetBackup removes the job artifacts for the completed job. No minimum interval or maximum interval. Default: 24 hours. Configuration entry default: SLP.CLEANUP_SESSION_INTERVAL = 24 HOURS |
Extended image retry interval | The amount of time to wait before an unsuccessful operation is added to the first job that runs after the delay. (This applies to all SLP jobs.) The extra time gives the administrator additional time to solve a problem that prevents job completion. No minimum interval or maximum interval. Default: 2 hours. Configuration entry default: SLP.IMAGE_EXTENDED_RETRY_PERIOD = 2 HOURS |
Unused SLP definition version cleanup delay | Concerns the deletion of SLP versions where a more recent version exists. The setting controls how long a version must be inactive before NetBackup deletes it. Default: 14 days.
Configuration entry default: SLP.VERSION_CLEANUP_DELAY = 14 DAYS
See Deleting old storage lifecycle policy versions. |
Tape resource multiplier | Limits the number of concurrently active duplication jobs that can access a single tape media storage unit to xx times the number of available drives. Allows tuning to avoid overloading the Resource Broker, yet makes sure that the devices are not idle. No minimum multiplier or maximum multiplier. Default: 2 (multiply access to the write drives by two). Configuration entry default: SLP.TAPE_RESOURCE_MULTIPLIER = 2 |
Disk resource multiplier | Limits the number of concurrently active duplication jobs that can access a single disk storage unit to xx times the number of available drives. Allows tuning to avoid overloading the Resource Broker, yet makes sure that the devices are not idle. No minimum multiplier or maximum multiplier. Default: 2 (multiply access to the write drives by two). Configuration entry default: SLP.DISK_RESOURCE_MULTIPLIER = 2 |
Group images across SLPs | If this parameter is set to Yes (default), multiple SLPs of the same priority can be processed in the same job. If No, batching can occur only within a single SLP. Configuration entry default: SLP.DUPLICATION_GROUP_CRITERIA = 1 Configuration entry for no, do not allow batching:SLP.DUPLICATION_GROUP_CRITERIA = 0 |
Window close buffer time | Sets the amount of time before a window closes when NetBackup does not submit new jobs using that window. Minimum 2 minute; maximum: 60 minutes. Default: 15 minutes.
Configuration entry default: SLP.WINDOW_CLOSE_BUFFER_TIME = 15 MINUTES |
Deferred duplication offset time | For deferred operations, jobs are submitted x time before the source copy is due to expire. Default: 4 hours. Configuration entry default: SLP.DEFERRED_DUPLICATION_OFFSET_TIME = 4 HOURS |
Auto create A.I.R. Import SLP | Used for Auto Image Replication, indicates whether an SLP (that contains an Import operation) is created automatically in the target domain if no SLP is configured there. Default: Yes, an SLP is created in the target domain. Configuration entry default: SLP.AUTO_CREATE_IMPORT_SLP = 1 |
How long to retry failed A.I.R. import jobs
| How long NetBackup retries an Import job before it stops and deletes the record. After the initial four attempts, the retries become less frequent. Default: 0 (do not retry after the initial four attempts). Configuration entry default: SLP.REPLICA_METADATA_CLEANUP_TIMER = 0 HOURS |
Pending A.I.R import threshold
| How long NetBackup waits before it generates a notification that an Auto Image Replication copy is still in import pending state. After an Auto Image Replication copy has been replicated, NetBackup puts the source copy into import pending state. If the copy is in import pending state for the time period that this threshold sets, NetBackup generates a notification. Notifications are sent to the NetBackup error log and are visible in the Problems report. Notifications may also be sent to an email address, if specified. Default: 24 hours Configuration entry default: SLP.PENDING_IMPORT_THRESHOLD = 24 HOURS See About Auto Image Replication import confirmation. |
Email address to receive notifications
| The email address that receives pending A.I.R. import notifications. Default: None. Configuration entry format: SLP.NOTIFICATIONS ADDRESS = user@company.com |
