Proactive Backup Error -519 ( network communication failed )

Recommended Posts

Hello,

We have a Retrospect 10 server with a proactive backup script, and this error appears in the script logs.

 

"!Trouble reading files, error -519 ( network communication failed )

 

We have 10 Mac clients all setup to backup proatively. This error appears in the logs for various clients at one time or another.

 

Questions:

1. What could possibly cause this error?

2. Where should I start troubleshooting?

 

Any tips/tricks on isolating the cause, or minimizing it as much as possible so we can get more successful proactive backups.

 

Our Configuration:

-Apple MacMini, 2Ghz ZIntel Core 2 Duo, 2GB ram

-OSX 10.6.8

-Retrospect server 10.1.0 (221)

-Retrospect client 11.0.0 (191)

 

Thanks for your time.

A -519 error means that the client no longer communicates with the Retrospect Server. The most common reasons are:
Client user disconnected the network cable.
Client user connected to another network using VPN.
Client computer shut down.
Client computer went to sleep.

Thanks for the information. I am going to have to work something out with our users/clients. All those situations you listed happen on our network on a dailey bases.

 

Thanks for your time.

From my experience clients accessed over a WiFi connection can have a higher incidence of this error too compared to when they are accessed over a wired connection.
