I manage approximately 90 iMacs in a school. We have just been set up with a Retrospect backup solution. All are fresh Yosemite (10.10.5) installs with Retrospect 12.5.0.111 client connecting to server on same version and same network.

 

I am able to add all the macs to the sources then add them into the scripts for our media sets (Photography, Media, Music). When the scheduled backups run however, the majority or connected machines fail returning error code -505 Client is Reserved. Maybe 3-4 successfully connect and back up in each media set.

 

I am able to disconnect (Cmd + click "off" on the client's retrospect configuration) then reconnect them so they don't report the error anymore but by the time they try to backup (an overnight process) they are reporting the same error again.

 

I really need to get this working as, at the moment, all our student's work on the macs is not being backed up, this is not an acceptable position for the school to be in.

 

Any help would be much-appreciated!

No, just the one on a mac-mini also running 10.10.5 and 12.5.0.111. Is it possible that there are just too many machines (up to 30) connecting at once and thus timing out. The -505 error seems to occur when connecting to a client then interrupting that connection.

For reference, the PhotographyNN are external hard drives. Those are a separate issue really (since they seem to be going to sleep despite energy saver settings).

 

As for what is interrupting the connection, I'm not sure. There is little other network traffic to speak of on-site at the times of these backups. Does Retrospect handle jobs sequentially or all in parallel? If it handles them in parallel then could it just be the inevitable slowdown caused by 30 simultaneous connections?

You seem to have network problems: -559 (network connection timeout) and -519 (network communication failed)

 

It might also be the external drives. Try running a backup with the external drives turned off/disconnected. (Just for test purposes)

 

Retrospect polls the clients in sequence for each script that runs. You might have more than one script running at the same time. But a "collision" for a client would give you another error code (and message): I think: "Client already in use by xxxx".

Our 3 scripts are set to run overnight spaced by 2 hours so that shouldn't be an issue.

 

Our infrastructure is solid so I'm more suspect of the external hard drives.

 

The following log from our Media suite however contains no external hard drives.

Is this your first Retrospect setup?

Did any old version work better?

 

I don't know what else to say.

 

Have you contacted Support?

Yes & I'm very grateful! This is our first setup with retrospect.

 

I'm going back to the company who set it up on our behalf to resolve the issue as it hasn't worked since day 1.
