Have server 2008 sp2 x86 (dual xeon )
need backup ~900Gb data (dwg , rar , zip, exe and etc data in total 800 000
files and 70 000 folders )
also nave backup server ( server 2008 x86 sp2 )connected over 1 Gigabit
ethernet
avarage send data speed from Areca :~19-23 Mb\sec
cpu load no more than 20-30%
both HDD from source and destination server average load no more then 20%
Anti-virus program unloaded on both server ...
for task no use compression ....
If you would like to refer to this comment somewhere else in this project, copy and paste the following link:
if i parallel with Areca copy data from server 1 to server 2
then my average Ethernet load ~70Mb\sec
but areca use only 10 % from gigabit Ethernet
have anu ideas how speed up Areca ?

Hi
How many cores do you have overall (two processors but how many cores by
processor ?)
Areca uses one thread by target so it only makes uses of multiple cores when
multiple targets are launched simultaneously. When you say that only 20-30%
CPU is used, it is likely that one of your cores is used at 100% while the
other ones are almost idle.
I've tried to implement producer/consumer patterns to make use of multiple
cores and speed up the backup process but to no avail for the moment
Best regards
