Dear All,

I kindly ask for help to solve the below problem:

My configuration:
OS: Centos 5.3
Bacula version: 2.4.4.1

I try to setup a backup process to backup just one database file (a 
mysql dump) for nightly backup over the internet (in order to have the 
backup off site). I am using this already for backing up other files and 
the connection works, only with large files, it seems bacula has a 
problem. The error is everyday exactly the same:

19-Mai 04:05 plato-dir JobId 206: No prior Full backup Job record found.
19-Mai 04:05 plato-dir JobId 206: No prior or suitable Full backup found 
in catalog. Doing FULL backup.

moving to end of data.

  FD termination status:  Error
  SD termination status:  OK

It seems like the network connection has been terminated sometime. But 
that is not true as it is a permanent connection with a static IP 
address on both sides. Furthermore, the line "SD Files Written:" states 
that there were two files written to the storage daemon. This is even 
one more than expected, it should only backup this one directory where 
there is only one file in it. And secondly the "SD Bytes Written:" line 
states nearly the bytes the mysql dump file had on that day (some bytes 
more than the file actually has). This means it actually wrote the whole 
file but after that I get an error or let's say the FD doesn't respond 
anymore or something. How can this happen? What could be a solution?

Thanks in advance.

Best Regards,
Benedikt.
