We're trying to increase backup to shared storage transfer rates. BUt Need to know which MB/s to use.
I assume it is best to use the TOTAL line from a backup email report then the MB/s within the detail log.
For instance if a TOTAL line looks like this:
TOTAL 00:32:21 101.91GB
then the actual MB/s would be:
32 Minutes x 60 + 21 = 1941 total seconds
101.91GB * 1024 = 104,355 total MB
size divided by seconds:
104,355 / 1941 = 53.7 MBs
that is a lot different the the detail parts of the log which show lines like these:
I assume the detail log MB/s is skewed due to doing calculation based on non compressed data? But I am not sure.
Which MB/s should be used to determine backup/transfer speeds?
