Hi Heiko!
I seem to have the same problem as you, without the client PCs being on a
different subnet, so it's a little easier for me. But i do not think this
actually matters.
After looking at the code of the main "BackupPC" script for a while,
- and adding a lot of additional logging output -
i noticed that the sub(routine) "QueueOnePC" does not put the Task into
the queue if the specified host is a dhcp one. To circumvent this, i simply
removed the "else {" from line 1718.
Also, the BackupPC_dump script exits with return code 1 if given the IP-address
instead of the hostname, so i changed the lines containg the "unshift"-commands
to fill the "host"-variable with "$host" instead of "$hostIP" in lines 1733,
1740 and 1748.
with these changes, BackupPC_dump is called correctly, but i don't know if i
broke something else in the process.
rsync is still running on my client, so i'm waiting for the incremental backup
to succeed or fail.
also, i'm not sure that this will fix scheduled backups as well.
I hope i can spend some more time on this tomorrow, and will report on my
progress
as soon as i make some.
Best regards,
Tobias Mayer
