I don't know about stalling, but leaving zombie processes is something
"normal". As far as I can tell, it happens when you dump multiple
directories or drives from the same machine. BackupPC_dump will fork
one process to dump the first directory, then one process to dump the
second one, and so on, but it will "reap" the children processes all
at once at the end. I don't know if this happens with "rsync" only
(that's how I use it and see it here) or with the other xfer methods
("tar", "smb") as well...
HTH,

I guess I don't care about the zombie, but since the backup never
"completes" something is obviously amiss. I suspect that once
"complete" maybe TrashClean or something clears away the leftover
processes; there are never zombies after a successful inc or full
backup, only when one hangs...
Maybe the zombie isn't the problem put some parent process never
realizing the subtasks are complete.
thanks

You backup a windows client, right? There should be a lot of files which can not be backuped because they are in use. Do you use volume shadow copies in windows? But nevertheless, you have backups of all files specified in your configuration. If you check your backup include/exclude configuration you should find which files are not backuped. br Matthias -- Don't Panic -- Let Crystal Reports handle the reporting - Free Crystal Reports 2008 30-Day trial.

Alternatively, you could just exclude the files that tend to be busy.

bonjour:
je viens d'installé backuppc sur mon pc(debian) et tous ce deroule comme il
faut,mais je comprend pas la signification des parametres lorsque je voulais
faire une sauvegarde à partir de la ligne de commande.le fichier de
restauration est comme suit:
%RestoreReq = (
'fileList' => [

'/lien~',
'/pdf2worddemofr.exe',
'/presentation.pdf',
'/rapport.pdf'
],
'shareDest' => 'folder',
'pathHdrDest' => '/',
'num' => '3',
'reqTime'=> 1248940328,
'shareSrc' => 'folder',
'pathHdrSrc' => '/',
'hostDest' => '172.17.3.11',
'hostSrc' => '172.17.3.11',

[BackupPC-users] Best practices for client-side unix user
Hi, I run BackupPC on ServerA, using the rsync method to get data from ClientA. (pretty conventional). If I want to perform a full backup of ClientA (all files, in all directories), what would be the best-pratices for getting the ssh/rsync user to read all that data? - Using root ? (probably not) - Creating a user that can read everything ? If so, how do you do that ? FYI: ClientA is Debian.
