We have a Windows 2000 server running ARCserve v.9 (build 2020) with a Plasmon 20 tape autoloader and have a 5-day weekly incremental backup with a full on a Friday rotation setup. Everything was working fine, until the job had to be recreated on Monday. Now the two UNIX servers will start to backup and will then display the following error...

E8535 - Failed to receive data from the client agent.

All Windows servers are fine.

This is a major problem and I'm not sure what the fix is. All help very much appreciated.

Thanks.

Start by putting the Job Engine and the client agent in debug.
    uagent start -v
This will put more detail in the uag.log file.

The first thing to find out is if data is being backed up at all.
If no data is being backed up, recreate the Uagent object in the backup window and setup the job again.
If data is being backed up and then the problem happens then there could be a network problem causing the timeout.

First of all,what is the unix version you are running - kernel version and OS version ? Checki if you
are able to run an individual backup of just a couple of files from the unix servers.Also if you goto

/opt/CA/uagent folder - you will find a uag.cfg file

add -m 1024 to the list of paramters and then run the backups.You can also try reducing the -m to        
512 and after which 128.Everytime you edit this uag.cfg file you will have to stop and restart the
uagent service.

Also add -v in the uag.cfg and run the backups,this will enable logging for the client agent for unix.
The log that gets generated would be called uag.log and it would be present under /opt/CA/uagent .

Apologies for not getting back to this thread.

The problem was due to "File Estimate" not being disabled after the backup job was recreated. This meant the UNIX agent would timeout before the file estimate was complete.
