Can anyone help or indicate where the definitions are listed? BackupPC_archive isn't very easy to use directly: reqFileName is the path of a file (output from perl's Data::Dumper) with information about what to archive. BackupPC_archiveStart is much easier to use. It creates a reqFile and then tells the BackupPC server to run the archive. Craig One of my earlier emails on this topic mentioned that BackupPC_archiveStart was not included in backuppc_3.0.0.-4ubuntu1_all-deb obtained from the main Ubuntu repository. (it is not listed in the .deb package filelist). Having read a warning in the BackupPC documentation not to mix files from different sources I assumed this had been deliberately omitted in favour of BackupPC_archive, and was therefore (mistakenly) attempting to use that file.

Greetings, I've been running BackupPC for a few months. I'm now thinking of disaster recover strategy. My initial thought is to replicate (via rsync) the BackupPC configs and data to another server. This server would not actively run BackupPC jobs, but I would like to be able to restore from it in the even to of a catastrophe. Is this a reasonable approach?

the rync algorythm is actually part of the GPL code released by Andrew Tridgell. Like I said, GPL is viral.

Re: [BackupPC-users] Native Window version of rsync
ahh! keyboard shortcuts are a mixed blessing! didnt mean to send it yet.here is the continuation If you have even looked at the code for rsync, you will likely be infringing on the GPL if you license this anything but GPL. This coud be true which is why I bought up my concern. That is why if there is any doubt, one should always perform a clean-room reverse engineering effort to produce compatible works. a clean room easily clears you from GPL violation. Additionally you might get the author to clear your code which would eliminate any issues as well especially if you credit the original author for inspriation or whatever. GPL coders are certianly influenced by such compliments. I am not some GPL nazi, I am just making this point. You might run into some other problems if using GPL code in a C# environment if you are using shared libraries that are not GPL. Another myth. Please stop spreading FUD. This is no myth. The GPL clearly states that GPL'd code cannot be linked with or to incompatible licensed code. *Some* shared libraries that may be used when programming in C# may be licensed in a non-GPL compatible license. Case in point: Stallman's standpoint that nvidia binary drivers violate the GPL because they link into the Kernel (GPL) but have a non-GPL compatible license. I'm just saying that one should be considerate of the shared libraries license. Go ahead and develope and license as you please. I am just making suggestions I wish these guys good luck and look forward to seeing their software progress. Considering that this is .Net, I'm looking forward to having an rsync client that will run on server2008/Vista 64bit as cygwin doesnt care for the 64bit part. - This SF.Net email is sponsored by the Moblin Your Move Developer's challenge Build the coolest Linux based applications with Moblin SDK win great prizes Grand prize is a trip for two to an Open Source event anywhere in the world http://moblin-contest.org/redirect.php?banner_id=100url=/___ BackupPC-users mailing list BackupPC-users@lists.sourceforge.net List:https://lists.sourceforge.net/lists/listinfo/backuppc-users Wiki:http://backuppc.wiki.sourceforge.net Project: http://backuppc.sourceforge.net/
