Limid bandwith on opimized duplication

Hi!

I'm duplicating from one msdp pool to another over WAN(I guess its called Optimized duplication).

On the first run there is quite a bit of data to be transfered and it is taking all my bandwith between the sites. Is there someway to limit it? because its going to take a few days and nowone can use the link meanwhile.

the link is around 20mbit today, if i can can tweak it to just use around 10mbit it would be great.

using to mediaservers with 7.5.0.3

 

Any ideas?

Thanks!

 

Daniel

    Two options for bandwidth throttling - the first which overrides any setting in the second option and is global across the pool is:

    Bandwidthlimit Path - edit the line "bandwidthlimit =" in:-

    Unix:/Storage/etc/puredisk/agent.cfg

    Windows: Storage\etc\puredisk\agent.cfg

    Second is the OPTDUP_BANDWIDTH setting found at:

    OPTDUP_BANDWIDTH Path :-

    Unix: /usr/openv/lib/ost-plugins/pd.conf

    Windows: install_path\Veritas\NetBackup\bin\ost-plugins

    If you just have a single server / appliance in each pool then you can just use the pd.conf and add the OPTDUP_BANDWIDTH = line with a suitable value .. this is in KB/s .. but this does work at stream level - if you user the agent.cfg it controls the whole thing as a total but again  vlaues and formulas are odd - I would guestimate that it would need a value of 20000 to give 20mb/s

    Hope this helps
