BPBKAR TEST
Not sure where you are quoting me from, but it seems you totally misunderstood.
Please always include URLs when you refer to other posts...bpbkar is NOT testing the network.
It is simply testing read speed from disk.
This is the first step to troubleshoot slow backups.If client is slow to read data from disk, there is nothing that can be done as far as network or media server or tape drive is concerned.
The bpbkar test is simply reading data from disk and sending it to the system 'null' device. meaning nowhere.
The bpbkar syntax is explained in http://www.symantec.com/docs/TECH17541
The following example would tell bpbkar32 to back up the F: drive to a null device.
To test NETWORK, you need to have a file of about 2GB and ftp it to the media server.
Firstly find out if the client can read fast enough from disk before you test the network.More reading matter:
