Problem backing up

[Robert Hoekstra]

Since a few weeks I have serious problems backing up a remote system (Cobalt server) with my Sun Solaris 2.6 machine. I backup different machines and different directories on each machine. all machines (including the cobalt) backup well, except for two directory branches on the Cobalt (the other one of three does backup, so network connection is not the problem!) If some information is missing in this message to solve the problem, let me know, I will provide the information asked.. Up to last week only one of three branches gave errors like amanda report below: btw. the amcheck results reported no errors...   ------------------- <amanda dumpreport message> -------------------- These dumps were to tape hosting-004. The next tape Amanda expects to use is: hosting-005.

It all has worked before.. I don't see why it shouldn't work anymore.. Can I delete indexfiles and infofiles which are stored on the Sun backup machine? could that be the problem?   The connection between machines is going over internet. All machines being backupped in above messages are behind the same firewall, so there are no different settings for the machines to be backuped.    Can one give me any hint to solve this problem? I am not that familiar to amanda to know what to do and what don't.   Thanks in advance   Robert ---- Shakespeare: 2B|^2B=?
