About MSDP storage capacity and usage reporting
Several factors affect the expected NetBackup deduplication capacity and usage results, as follows:
Expired backups may not change the available size and the used size. An expired backup may have no unique data segments. Therefore, the segments remain valid for other backups.
NetBackup Deduplication Manager clean-up may not have run yet. The Deduplication Manager performs clean up twice a day. Until it performs clean-up, deleted image fragments remain on disk.
If you use operating system tools to examine storage space usage, their results may differ from the usage reported by NetBackup, as follows:
NetBackup usage data includes the reserved space that the operating system tools do not include.
If other applications use the storage, NetBackup cannot report usage accurately. NetBackup requires exclusive use of the storage.
Table: Capacity and usage reporting describes the options for monitoring capacity and usage.
Table: Capacity and usage reporting
Change Storage Server dialog box
The Change Storage Server dialog box Properties tab displays storage capacity and usage. It also displays the global deduplication ratio.
This dialog box displays the most current capacity usage that is available in the NetBackup Administration Console.
You can see an example of the dialog box in a different topic.
Disk Pools window
The Disk Pools window of the Administration Console displays the values that were stored when NetBackup polled the disk pools. NetBackup polls every 5 minutes; therefore, the value may not be as current as the value that is displayed in the Change Storage Server dialog box.
To display the window, expand Media and Device Management > Devices > Disk Pools.
View container command
A command that is installed with NetBackup provides a view of storage capacity and usage within the deduplication container files.
See About MSDP container files.
Disk Pool Status report
The Disk Pool Status report displays the state of the disk pool and usage information.
Disk Logs report
The Disk Logs report displays event and message information. A useful event for monitoring capacity is event 1044; the following is the description of the event in the Disk Logs report:
The usage of one or more system resources has exceeded a warning level.
By default, the threshold (high-water mark) for this message is at 98% capacity. No more data can be stored.
See Viewing MSDP disk reports.
The nbdevquery command
The nbdevquery command shows the state of the disk volume and its properties and attributes. It also shows capacity, usage, and percent used.
The NetBackup OpsCenter also provides information about storage capacity and usage.
