Hello,
I'm having a problem with a windows 2003 server since some weeks.
The problem appears to happend randomly when I run Full backups (Some
full backup jobs end successfuly, while others don't). This is an
example of the error:
-

I'm doing backups of this machine since a year and a half, and just
recently it started with this error. The data volume has kept somehow
constant, between 40 and 50 GB during this period.
- - The ethernet cannot be because it's been always the same, we haven't
changed it.
- - The client did not have the Heartbit interval option set, so I set
it; but the problem persists.
- - There have been no changes in the firewall (apart, there is another
windows machine behind the firewall that uses bacula too, an it
doesn't have any problem).
- - The amount of data transfered cannot be the problem, because until
some time (when the full jobs ended right :-) ), the data transfered
was between 40 and 50 GB.
- - Might it be a problem between the bacula versions? Do you suggest
any probe that I could run?
My setup is the following:
Windows 2003 FD <----> Linux machine doing NAT <-----> Linux machine
running Bacula SD and Director
Versions, according to the output of "status storage", "status
director" and "status client":
- - Bacula dir: Version: 2.4.2 (26 July 2008)
- - Bacula sd: Version: 2.2.8 (26 January 2008) i486-pc-linux-gnu
debian lenny/sid
- - Bacula fd version:
server2003-fd Version: 2.0.0 (04 January 2007) VSS Linux
Cross-compile Win32
Daemon started 01-Oct-08 13:35, 70 Jobs run since started.
Heap: bytes=101,724 max_bytes=295,310 bufs=100 max_bufs=230
Sizeof: boffset_t=8 size_t=4 debug=0 trace=1
I set the Heartbeat Interval option for every hour: "Heartbeat
Interval = 3600"
So my fd config file looks like this:
-
---------------------------------------------------------------------------------------------------
FileDaemon {
Name = server-fd
FDport = 9102
FDaddress = an_ip
WorkingDirectory = /var/lib/bacula
Pid Directory = /var/run/bacula
Maximum Concurrent Jobs = 20
Heartbeat Interval = 3600 # a cada hora
}

---------------------------------------------------------------------------------------------------
Here there are two failed backups, as examples (Note: xxxxxxxxxxxxxx
is the public IP of the firewall doing NAT):
