BackupPC has an account _backuppc on OpenBSD (backuppc on Debian) which has to have permissions on the system that it is backing up. LDAP is the one responsible for granting the permissions.
Configuration within BackupPC (a pain) is specifies what a user can see in the backups and what a user can restore. The busy file problem occurs when using a Windows system not a Unix system. Using a Windows system there is no way to look at an open file unless shadow copies are used and you are not going to use that more than once a day. I tried to create a shadow copy before a backup but I found created shadow copies unreliable with too many random errors. I probably should try again to use shadow copies before a backup, hoping that Microsoft has fixed the problems, but I haven't done it. My backups are taken early in the morning and rarely is any one a computer. Also the shadow copy has special deals with things like Exchange and the MS-SQL giving the net effect you can't use shadow to get a copy of the database anyway. As far a dump and rsync.,I didn't say there were no other ones. I gave a reasonable google search. You can try it. I would have expected you to say rsnapshot which is a good package. I use it to back up my DMZ machines (all OpenBSD). Backing up Windows machines is my problem; I want it automated and fool proof as possible. -----Original Message----- From: Jan Stary [mailto:h...@stare.cz] Sent: Tuesday, December 10, 2013 12:13 PM To: Peter Fraser Subject: Re: BackupPC On Dec 10 15:53:52, p...@thinkage.ca wrote: > I have not had any troubles with BackupPC (on the Debian system). > BackupPC does deduplication which I don't believe that Bacula does. > From the point of view of the clients the backups are done automatically, as > long as they leave their computers on and connected to the network. ... and let someone from somewhere read their disk.

Bullshit; dump and rsync can do hardlinks and symlinks.
