Network-Transfer Rate
The network-transfer rate considers only the time required to transfer data
over the network from client to server. This rate ignores:
• Time to load and position media before a backup.
• Time to gracefully close the tape file and write an additional NetBackup
information record to the tape.
The network-transfer rate is the one provided in the All Log Entries report.
Network-Transfer Plus End-of-Backup-Processing Rate
This rate ignores the time it takes to load and position media before a backup,
but includes the end-of-backup processing that is ignored in the network
transfer rate. To determine this rate, use the All Log Entries report and
calculate the time from the message:
begin writing backup id xxx
to the message
successfully wrote backup id xxx
Then, divide this time (in seconds) into the total bytes transferred (as recorded
in the All Log Entries report) to calculate the transfer rate.
Total-Transfer Rate
This transfer rate includes the time for loading and positioning the media as
well as the end-of-backup processing. Using the List Client Backups report,
calculate the transfer rate by dividing Kilobytes by Elapsed Time (converted to
seconds).
Examples
Assume that the reports provide the following data.
