Item 45?: Improve how bacula handles tcpip connections when they drop (or are just not answered) unexpectedly both at the beginning and in the middle of a backup. Date: January 29, 2008 Origin: Bob Hetzel [EMAIL PROTECTED] Status: New
What: Part A: Currently, when a bacula client has a firewall on it that isn't set up properly to allow the server to connect in (or is just down), it takes bacula a long time to figure that out. Part B: When a client goes away in the middle of a backup (i.e. shut down or just taken off the network due to being a laptop on the move) bacula takes a long time to figure that out and terminate the backup. Why: Workarounds have been suggested such as creating a "before job" that pings the client. That is only a partial resolution to part A and is no resolution to part B, because it tests general connectivity to the client without specific bacula connectivity (i.e. response to a ping is not the same as response to a connection on port 9102). In addition, that doesn't resolve the problems created when backing up a laptop or other computer that gets shut off or moved in the middle of a backup. Also, many IT shops have created policies to turn off ping responses due security situations they can create, for instance under Microsoft Windows. Notes: It seems rather obvious to me that implementing part A is substantially easier than part B, but both seem rather related and could share code. Part A would be really nice even without part B. though. This would also allow the code to give a better message to the server which currently just suggests a password problem or bacula not running. Having a way to check if the director connected at all to the bacula client would allow for a more specific error message. I also understand that this might require a change in the FD code--thus making older clients incompatible with the newer bacula server daemons, so perhaps a way to turn it on or off would be helpful too. ------------------------------------------------------------------------- This SF.net email is sponsored by: Microsoft Defy all challenges.
