Do you still think it is a transient file issue? That's 'not supposed' to happen on filesystems with unix semantics. That is, if a process gets a file open, it is supposed to continue to have access to it's data even if some other process removes or renames it. It could happen if another process truncates it - which doesn't seem likely for programs using maildir format. It also might happen over an NFS mount, although NFS goes through some contortions to avoid it. In any case, it is somehow related to filesystem activity and probably doesn't hurt much as long as you can restore the other files. But this error occurs in the same position day after day, increasing in number of times it is found in the log. Now for a dumb question: Does that error indicate a problem on the backuppc server or the server being backed up? I have been assuming the whole time it was the backuppc server.

I'm not sure how it handles incrementals but using the native backup api on windows clients might have some advantages. The bacula client also has the same problem of not being able to intelligently detect moved files/directories. Rsync looks to be the best solution. - Take Surveys. Earn Cash.

Re: [BackupPC-users] Client Push revisited
John, I have used two approaches to this problem. 1. Change to rdiff-backup for the mobile clients. It does not have the GUI, but it does have a nice command line for dealing incrementals, expiring incrementals, etc. I use it on my laptop. 2. The second option is more time consuming to set up, but I am using it for a system that backups 1400+ workstations. On each workstation I run a small script that updates Openldap with the workstation IP and Mac address. Then I have a script that creates a DHCP hosts file and restarts the DHCP server. This along with Dynamic DNS means that each laptop ends up with a single network name no matter which physical network it is on so BackupPC can get to the laptop to back it up. This should be easier if you are running Active Directory as Microsoft workstations add entries to AD when they get an IP. cheers, ski John Locke wrote: Hi, I've gone through the archives, and found messages from 2003 about client push (backups initiated from client machines to the backup server) being on the long range plans. Has any work progressed on this front? I've got a couple networks I'm managing that have roaming Windows laptops. They already run Rsync via Cygwin to do essentially a straight copy to the server, not using BackupPC at all. The backup server already provides rotating backups, using hard links to make copies of the existing backups but only use disk space when a file changes. It would be great to have access to these backups via the CGI script. Alternatively, it would be fantastic if backuppc acted like an Rsync server, accepting client connections from a remote Rsync sender, and adding these files according to the BackupPC storage system. Are there any current plans for implementing either system? I don't currently have bandwidth for working on this, but if there's a relatively straightforward place to start developing this sort of functionality, I may be able to free up some developer time to work on this sort of thing...

This isn't the issue--I've already got DHCP updating DNS with client hostnames. BackupPC can find the hosts, no problem. The issue is that I would rather keep server software (rsyncd, ssh, Windows Networking/Samba) off my mobile clients, and initiate backups from them so they don't have to enable/disable firewalls, etc. when connecting to untrusted networks.
