It's not like it's hard to insert an executable manifest - I've even replaced manifests in 3rd party software I don't have source to without significant hassle. Win7 and win2k8 offer an excellent built-in image backup system that makes proper use of VSS to get a consistent copy, so this seems a bit obsolete. I guess for 2k8 server it'd be handy. -- Craig Ringer Tech-related writing: http://soapyfrogs.blogspot.com/ -- ___ Bacula-users mailing list Bacula-users@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/bacula-users

Calm down, people. There is ERUNT. http://www.larshederer.homepage.t-online.de/erunt/ I have not tried it with my current Win7, but at XP/2003 times it worked like charm. I took daily backup which Bacula could put to tape without any problems, and the backup contains an executable to restore each copy.

Actually you'd just need to write a little app that made a call to RegReplaceKey (http://msdn.microsoft.com/en-us/library/ms724913%28VS.85%29.aspx). Interestingly the documentation regarding VSS restore of the registry says you should use MoveFileEx with a parameter of MOVEFILE_DELAY_UNTIL_REBOOT to replace the registry hive with the restored file, but if you do that your system blows up, so don't do that :) James -- ___ Bacula-users mailing list Bacula-users@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/bacula-users

To restore the hives you'd have to boot a different Windows install with the Bacula agent running and the disks for the win2k3 server attached. You can't restore onto the 2k3 machine's registry hivesbecause they're read-only to applications while the OS is using them. You *may* be able to restore them to an alternate location on the running server's disks, then reboot into the recovery console and move them into place, though. Honestly, you're probably better off restoring your disk-image backup of the server then updating the user data from your backups. That's usually by far the easiest way to repair a dead Windows server. ( Please don't say "what disk-image backups?" You're running Windows servers, so you must keep some kind of disk image backup of the OS install... ) Looking at MSDN, it appears that Bacula may have to explicitly support the VSS registry writer to do registry backups. See: http://msdn.microsoft.com/en-us/library/aa384595%28VS.85%29.aspx OTOH, since the default paths appear to be under \Windows\System32\config\, then with vss enabled it may be that the hives can be automatically backed up. If you've excluded that directory, you're almost certainly out of luck. Check the registry key mentioned above to see if that's where the hives are saved by VSS - if it's a different location you could be lucky. Even if it is, restoring the hives could be ... interesting. See the MSDN article referenced. Maybe it's easier with the recovery console. Ugh. Reading this stuff, I'm beginning to feel sorry I recently bought a Win2k8 server. Still, it was that or an Apple XServe to replace the destroyed-by-water old XServe, and unlike Apple at least Microsoft fixes bugs faster than they introduce them. -- Craig Ringer Tech-related writing: http://soapyfrogs.blogspot.com/ -- ___ Bacula-users mailing list Bacula-users@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/bacula-users

VSS does provide a consistent snapshot. IMHO the "VSS Writer" loglines just mean that the Service xyz was informed about a snapshot that will happen so that Service xyz can get into a consitent state on disk. this does not mean that anything is written an tape/volume. - Thomas -- ___ Bacula-users mailing list Bacula-users@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/bacula-users
[Bacula-users] Windows registry restore possible?
I'm primarily a Linux user, and have been quite happy with Bacula on Linux. I also have some Windows servers which I'm stuck managing as well, and I have Bacula configured on those. One of those servers, a Windows Server 2003 machine, recently managed to corrupt its SOFTWARE registry to the point that it wouldn't boot. Is it possible to restore just the registry without restoring the entire backup? I have the VSS enabled in the Bacula config, and the email log from a recent backup makes it sound like the registry is being backed up: 21-Apr 00:49 zz-fd JobId 37835: VSS Writer (BackupComplete): "Registry Writer", State: 0x1 (VSS_WS_STABLE) If I could find a saved registry hive file from this backup, I'd be happy - I used the recovery console to restore an earlier hive file, which got the server back up, but that was a save point from a service pack install and is not very recent. One problem may be that my default Windows exclude list which I picked up somewhere includes this line: WildDir = "[A-Z]:/WINDOWS/system32/config" The registry hive files are stored in this directory on disk, but I'm hoping the VSS snapshot saves them elsewhere. Searching the database for the filename "software" shows only the "repair" copy installed when Windows was installed: $ find software C:/WINDOWS/repair/software Thanks in advance for any suggestions. -- ___ Bacula-users mailing list Bacula-users@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/bacula-users
