About Storage Lifecycle Policy reports
This section describes the Storage Lifecycle policy reports that provide information about the NetBackup Storage Lifecycle Policies (SLP's)and NetBackup Auto Image Replication (AIR). It also inludes detailed information on SLP sizes, progress, and backlog per Master.
The Storage Lifecycle Policy reports in OpsCenter help you gain an end-to-end visibility across destinations in a storage lifecycle policy. With the Auto Image Replication functionality, you can replicate images from one NetBackup domain to another NetBackup domain. You can specify a different master server as a storage destination in an SLP. The SLP reports in OpsCenter show an end-to-end view of the SLP process that includes backup to import of duplicated image into different NetBackup domains. The SLP reports help you to verify if each step in the SLP is executed and identify the possible bottlenecks.
The Storage Lifecycle Policy reports in OpsCenter help you find answers to the following questions:
Is the SLP performing according to schedule?
Have the 2nd, 3rd… Copies been made? Does the original image still exist?
Am I at a risk of data loss? A copy at a certain phase is about to expire and the subsequent phase's copy has not been made.
What is my backlog? Is it getting steadily worse?
Review the following points about SLP reports:
The SLP reports are applicable only to NetBackup.
The SLP reports can be run only for 7.1 or higher master servers. If you upgrade from 7.0 (or 7.0.1) to a 7.1 master server, the SLP reports also show the images for 7.0 or 7.0.1 master servers.
If you upgrade NetBackup from 7.0 or 7.0.1 to 7.1 and the SLP definition contains multiple backup operations, then the first copy is marked as "Backup" and the remaining are marked as "Duplication". For example, if you created an SLP that contains four destinations where two destinations are for backup and two are for duplication, then image copy data marks the first copy as Backup and remaining for Duplication.
The data that is shown in the SLP reports is collected from the NetBackup catalog and the SLP worklist by NBSL. Once the initial data collection is complete, the updated data is collected from the NetBackup catalog in every 15 minutes and from the SLP worklist in every 10 minutes. The SLP worklist is located in the EMM and contains metadata like how many copies need to be created, where they need to be created, when they are completed etc.
The data that is displayed in the SLP reports is based on the image data that exists in the SLP worklist and the NetBackup catalog.
The effects of deduplication, compression, or optimized deduplication on image or copy size are not considered in the SLP reports.
By default, data for SLP reports is purged from the OpsCenter database after 90 days. You can also customize the purge interval for SLP images from Settings > Configuration > Data Purge.
In general, the copy data in the SLP reports (like Copies Completed column) is based on the data that is collected from the SLP worklist. EMM creates the SLP worklist once a backup is complete. OpsCenter collects this data in every 10 minutes and shows it in the SLP reports. Depending on when the SLP worklist is created and also the OpsCenter data collection cycle, the OpsCenter consoles show details for the copy data.
The timeframe filter for all SLP reports is based on the time when the primary backup image (and not an image copy) was created. For example, if you view the SLP Status by Image Copy report between 7'th May 1:00 P.M. to 8'th May 1:00 P.M., then the copies that got created for an SLP after 8'th May 1:00 P.M. may be displayed. These copies may be displayed as the timeframe filter is based on the time when the primary backup image was created and not on the copy creation time.
SLP reports do not consider non-SLP based duplications.
Creating custom reports for SLP's is not supported.
The following are two high-level SLP reports:
|
SLP Status report |
See SLP Status report. |
|
SLP Backlog report |
See SLP Backlog report. |
Before using the SLP reports, you must understand the SLP and Auto Image Replication concepts in NetBackup.
