Methods for determining the NetBackup transfer rate
Calculate three variations of the backup transfer rate by using NetBackup report data.
Three NetBackup transfer rates and calculation methods are available.
Table: NetBackup transfer rates
On Windows, the Microsoft Windows System Monitor also displays the NetBackup transfer rate.
Assume that the reports provide the following data.
Sample All Log Entries report:
TIME SERVER/CLIENT TEXT 04/28/09 23:10:37 windows giskard begin writing backup id giskard_0767592458, fragment 1 to media id TLD033 on device 1 . . . 04/29/09 00:35:07 windows giskard successfully wrote backup id giskard_0767592458, fragment 1, 1161824 Kbytes at 230.325 Kbytes/sec
Sample List Client Backups Report:
Client: giskard Backup ID: giskard_0767592458 Policy: production_servers Client Type: Standard Sched Label: testing_add_files Schedule Type: Full Backup Retention Level: one week (0) Backup Time: 04/28/09 23:07:38 Elapsed Time: 001:27:32 Expiration Time: 05/05/09 23:07:38 Compressed: no Kilobytes: 1161824 Number of Files: 78210
The following three rates were compiled with the backup data from the sample reports:
Network transfer rate:
1161824 KB at 230.325 KB per second
Network transfer plus end-of-backup processing rate:
23:10:30 - 00:35:07 = 01:24:30 = 5070 seconds
1161824 KB/5070 = 229.157 KB per second
Total transfer rate:
Elapsed time = 01:27:32 = 5252 seconds
1161824 Kbytes/5252 = 221.216 KB per second
