About reporting the amount of Accelerator backup data that was transferred over the network
For Accelerator backup reporting, several NetBackup commands can report the amount of data that is transferred over the network for each Accelerator backup. The amount of transferred data is often much less than the size of the Accelerator backup image.
For each Accelerator backup, NetBackup combines the client's (or VM's) changed blocks with the unchanged data from previous backups to synthesize a backup image. However, NetBackup sends only the changed data over the network when the backup occurs. The resulting backup image may be much larger than the amount of backup data that travels the network. For backup reporting, it may be important to distinguish between the backup image size and the amount of data that was transferred over the network.
For Accelerator backups, the network-transferred data can appear in the output of the following NetBackup commands: bpdbjobs, bpimagelist, and bpclimagelist.
Table: Default location of bpdbjobs, bpimagelist, and bpclimagelist lists the default location of these commands.

The following example uses the bpimagelist command to show the results of a backup of acmevm2:
bpimagelist -backupid acmevm2
Example output:
In this example, the backup image size in kilobytes is 7799632, and the amount of data that was transferred over the network is 225792.
You can use the following commands to show the amount of data that was transferred over the network for an Accelerator backup.
bpimagelist -backupid backup_id [-l | -L | -json | -json_compact]
Brackets [ ] indicate optional elements, and the vertical bars | indicate that you can choose only one of the options within the brackets.
Table: The bpimagelist options that show the amount of network-transferred data for Accelerator backups describes how the network-transferred data field appears in the bpimagelist output.
Table: The bpimagelist options that show the amount of network-transferred data for Accelerator backups
bpimagelist option | How the network-transferred data field appears |
|---|---|
No option | The field is unlabeled. For example: 225792 See the bpimagelist example output earlier in this topic. |
-l | The field is unlabeled (same as no option). For example: 225792 |
-L | The field is labeled. For example: Kilobytes Data Transferred: 225792 |
-json | The field is labeled. For example: "kilobytes_data_transferred": 225792, |
-json_compact | The field is labeled. For example: "kilobytes_data_transferred":225792, |
bpdbjobs - jobid job_id -report - most_columns
or
bpdbjobs - jobid job_id -report - all_columns
The network-transferred data field appears at the end of the output.
bpclimagelist -client client_name
This command can only show the network-transferred data in the field that normally shows the Accelerator backup image size. To show the network-transferred data with this command, you must configure a NetBackup setting:
See Replacing the Accelerator image size with the network-transferred data in NetBackup command output.
Additional details on these commands are available in the NetBackup Commands Reference Guide or in the NetBackup man pages.
