Backup exec running at 3.00MB/sec

[djh]

Hi,

We are currently running backup exec with 9 windows servers and 1 mac server. I have setup the remote agent on the mac server using the script and all looks fine, I can browse the server and the crednetials are all working fine. however every morning i come in and the backup is still running. AT 3MB/second! Can anyone shed any light on why this is so slow?

One thing worth mentioning is that the mac server doesn't appear under macinstosh resources, I have to browse for it manually within the domain list.

Many Thanks,

Dan

Does this only affect the mac servers backup?
What are you backing up to?

Symantec provide their own drivers for tape drives on windows servers. These have increased the speed of the backup in my experience. Maybe there is some symantec driver thing for the MAC.

I agree, I've done a lot of BackupExec installs and this is normally a driver issue.
In the Tools menu you can install Symantec Drivers for your tape device. Don't forget to reboot

Hi guys,

It's just backing up to the disc at the moment, the full backup tonight will go to tape but haven't tried that yet. It's literally backing up from the mac hdd to the backup srv hdd.

Thanks,

You could sniff the network traffic between the mac and the server to make sure that you are not getting lots of corrupted packets and retransmissions ?

Sounds like a network issue. Try copying a file between the two servers, if the speed is slow then check your switches and cables. Perhaps you have a switch port with a lot of collisions or crc errors.

try this from the backupexec server:

ping macserveripaddress -t -l 2000

do you get packet loss?

Ran the ping with 2000 bytes, and it says request timed out, and then it wont even ping, yet I can ping from the mac server to the backup server, weird. Any ideas? I'm fairly new to all this, the network engineer has gone traveling for 2 months so i'm left holding the fort.

Ah OK, if i ping ks-macsrv i get a response, and it resolves the IP address, but if I ping the ip address it does request timed out....

Are both servers attached to the same switch? If they are try using different ports and swapping network cables.

If you the servers are on different switches then I would test connecting the servers to the same switch to eliminate any inter-switch communication issues.

Getting late here, but the key to this problem is to get the pings working in both directions. Once you get the network issue sorted, BackupExec should work fine. Hope that helps.

Can you paste the result of ipconfig /all from the windows server enter this into the command line
and
The result of ifconfig on the mac Enter this into a terminal

Also
I guess ifconfig will work on the mac as its Unix based if
not anyone got a better idea ?

Hi, OK have got it all pinging each other, and no packets are lost and everything is under 1ms so it's all working fine, but the speed will still not get beyond 3.00mb/sec. Infact now it's gone down to 2.00meg.

Are you talking about Megabytes per second, or megabits per second there?

[djh]

MB, mega bytes.

[spc-rocket]

MB, mega bytes.

Doesn' Backupexec display this in MB/min (i.e. megabytes per minute)?
