Okay more details. My network has 4 systems on it. The two important systems in this case are praxis and buffy. praxis is a linux system running debian woody(2.4.19 kernel), and buffy is a toshiba laptop running windows XP.
I ran a full save backup on buffy using the ntbackup tool that comes with XP. This was run last thurday or friday(I forget which.) The next day I tested restoring a cpl of files from the backup and it worked great. Due to some CD issues, I couldn't do the rebuild restore that day, so I waited until last night. I decided to run an incremental backup, and when the thing thought that EVERY file had changed, I decided well, that's bogus, we'll just go with the full I made before. I also decided to use a different filename for my backup(I checked append to backup as well.) Here's where I made my major error I think, I didn't check to make sure the backup file was still there before I reinstalled. I suspect(not knowing enough about the ntbackup tool, I do not know) that when I ran the incremental, it decided to delete my old backup file. Why it did this, I do not know, nor can I understand why anyone would think the simple change of a filename would mean the old filename was unimportant. Anyways, after I ran the reinstall and added the basic driver packages, I went and lo and behold my backup file was empty. The original name was "Jeanette Backup.bkf" and the name I chose to make the incremental was "Jeanette Backup2.bkf". The system is running samba 2.2.3a. There is nothing useful that I can see in any samba logs. I did notice something I was unaware of, the laptop that I call buffy was not in my static DHCP table, ie, it is getting various IP addresses and names. I wonder if that could have an effect? I went thru the filesystem that I stored the backup on and tried to search for the file with debugfs, but either because the file was too large(recover segfaulted on me) or some other reason. Ive tried the tricks I know to recover a file, and have failed, so Ive pretty much given up on my data, but ANY help would be greatly appreciated. Oh, the laptop XP system did have its latest patches installed(everything on windows update.) My samba uses user authentication, and other than only allowing connections on my local subnet, has no other configuration... Please let me know any other details needed.
