Retrospect problems on Mac/PC network

Hi.

I just started working for a company that uses Retrospect V. 6.1.126 on a G4 Mac Desktop running OS 10.4.9 and
has multiple clients. I have never used Retrospect myself but I'm trying to find a solution to a problem with
their Retro.

I'm in the graphics department which consists of three Macs. Retro. is running off one, the G4 I mentioned before. It has
1.5 GB of SDRAM and is a Dual 450mhz processor. The Retro on that G4 Mac backs up all the PC's in the company
(12 PC's running Windows XP) plus the Macs in the graphics department but since January 2007, the Macs aren't being
backed up but the PC's are backed up just fine. Prior to January, the Macs were able to be backed up. The Macs are running
client 6.1.130. One of the other Macs is a G5 Desktop, 2 GB SDRAM, Dual 2ghz processor. The one I'm on is a 2ghz Intel
Core Duo, 2 GB SDRAM iMac. All the Macs are running Tiger. The client Macs are on the same subnet as the Retro. installed Mac
and they are networked through a centralized data port.

What's happening is that, while trying to back up a client/computer, Retro. only reaches the point where it begins
to back up files but then hangs up. The Log states "Trouble reading files, error 519 (network communication failed)".
Supposedly, Retro. has worked fine the entire time they've been using it up until about January 2007. It only backed up
628 files out of something like 42,000 and stopped at #628.

I downloaded the newest Driver yesterday and installed it- 6.1.10. It had 6.1.9. Restarted the computer.

The driver update didn't help.

The problem already existed with RDU 6.1.9.102. I only installed RDU 6.1.10.100 yesterday to try to fix the issue of
Retro. not completing the back up process.

Any suggestions? I'd reallly appreciate it.

No particular solution to offer, but some things that might be worth checking:

Are any of the Energy Saver settings configured in a way that the first Mac to be backed up is going comatose during the scan?

Does the problem occur if the users are logged out of their Macs?

Can you suspend execution on 2 of the machines and see if it will back up the 3rd?

Is there any sort of VPN software running that might be interfering with the client communication?

well the first thing is suggest is to check that the backup clients that are installed on the computers are up to date. the second thing i suggest is to check that in the prefrences of the retrospect server in networking is set to not cancel the backup if network speed falls below "(whatever speed set)" make sure that it is not set to use that. i do have a set up in my business just like yours and no problem. one more thing if you could post the retrospect log file i could help you more. make sure it is the one that shows all the actions that the retrospect server is doing. happy sailing!

I use everything you are dealing with except 10.4.9. I stayed in 10.4.8 on both Server and Clients till all issues where resolved.
As far as error 519 (network communication failed), this is 9 out of 10 time a client issue and has nothing to do with the Retrospect Server unit.

Please go back to your post in the EMC Forums I posted more info there since thats realy where it belongs. (even thought by you coming here made me go there, lol)

BTW all His Version info client and server are up to date. The hang might be an RDU issue so you might want to go back one.
