B&R Processing Rate and throughtput units

Post by Dimitripietro »

Hi,

Is the processing rate in Megabits per second or per megabytes per second ? What about the throughtput ?

Thx !

Hi Dimitripietro,

Processing Rate is measured in MBps (MegaBytes per second),
Throughput in general is measured in Mbps(Megabits per second), however sometimes for your convenience we show it measured in MBps(MegaBytes per second). Thanks.

[MERGED] Megabyte or megabit pr. second

Post by Robvil »

Hi,

Looking in B&R console at the status result for a backup job, it displays network speed in MB/s.
But is this in MB (megabyte) or Mb (megabit)?

MB = Megabytes, Mb = Megabits

correct... If I am not mistaken we use 2 formats.
MB/s => MegaBytes per second (data processing)
Mbps => MegaBit per second (network)

Then i dont´t get it. Veeam B&R says the backup speed was 197MB/s which equals 1800-1900Mb/s.
My zabbix monitoring says it never goes over 1Gb/s on my repository server.

Hi Robert, please note that processing rate is not a throughput, but total VM size divided by total VM processing time.

And these are different values anyway.
Processing rate is messured on the read side before dedup and compression.
When you look at the repository, you see the dedup and compressed stream. So less than half of the data.
