I have been having numerous problems backing up 5 remote machines when using Retrospect. My Retrospect backup system is set up on a Macintosh Server 8550 with 96 megs of Ram 16 Gigs of hard drive space. I am using a Sony AIT tape drive. I am using Retrospect 4.2. This location has 512kps DSL. I have 2 Imacs out there one is connected through 256kps DSL and the other is connected through ISDN. I also have a PB 3400 and two 7100/80's. All machines are set up as TCP/IP. The DSL is set up as an ATM over PPP (I am not sure exactly what that means, but I know it is important). The problem is simple I get 519 errors about 60 - 70% of the time. The question is how should Retrospect be configured so that I can make sure that I am getting consistent backups every night. Is there a specific Port that Retrospect access? Any help and suggestions would be appreciated.
