Hi Marco,
The following works for me.
$Conf{RsyncShareName} = {'/Users'}, i.e. backup where the user folders are + to
exclude the folders of Admin, Guest by $Conf{BackupFilesExclude} = {'*' =>
['Admin/','Guest/']}.
Hope it helps.

Subject: [BackupPC-users] A few questions
Hello all,
I used to use BackupPC some time ago and it was really great. Now I have a
chance to use it for a project, and I have some (surely simple) question.
Apologies if some of this is alswered already, pointers to documentations are
welcome:
- Using rsync, what's the syntax to tell BackupPc to not backup any data for a
given host? I only want to run a DumpPreUserCmd without dumping any data. I've
tried every variation of $Conf{RsyncShareName} $Conf{BackupFilesExclude}. Among
others, I thought unsetting $Conf{RsyncShareName} or using
$Conf{RsyncShareName} = [ '/' ] and $Conf{BackupFilesExclude} = [ '/' ] should
work, but no luck, the whole / is still backed up. Of course I could create a
dummy directory and back that up, but I think it should be possible to do what
I'm trying to do.
- How do people run DumpPreUserCmd etc. on windows machines?
- In a host configuration file, if I try to redefine values coming from the
main config by adding values to them (for example:
push @{$Conf{RsyncArgs}}, '-4';
to get the -4 extra option when backing up this particular host), the dump
fails with "aborted with signal=PIPE". If I run the dump manually, I dee that
the extra option is being used, but then the backup fails, here the full output
(for localhost, but it fails equally woth any other host):
$ /usr/share/backuppc/bin/BackupPC_dump -v -f localhost

Got fatal error during xfer (aborted by signal=PIPE)
Backup aborted by user signal
Not saving this as a partial backup since it has fewer files than the prior one
(got 0 and 0 files versus 0)
dump failed: aborted by signal=PIPE
Sure enough, if I put the -4 in the main config, or redefine $Conf{RsyncArgs}
entirely without making reference to its previous value, the backup succeeds.
I'm not sure what's going on here; should what I'm doing be possible?
- What exactly is "BackupPCd" (note the "d" at the end)? It is mentioned in
config.pl<http://config.pl> but I can find no documentation.
Thanks in advance for any help.
