Samba is not my expertise, so I won't presume to give you debugging advice. I will say that I have been able to get Samba and Windows working quite well together to share files and printers on multiple occasions. When I have had problems using Linux as a server, it is usually because on the Linux side, I have not created the users with smbpasswd program (just because they exist in /etc/passwd doesn't mean that they exist for Samba - although I think there is now an option to propagate changes back and forth). You can also webmin and swat to manage Samba via a browser.
Since Windows file attributes are not the same as Linux, I only recommend using Windows to backup your Linux files by first creating a tar archive on Linux and moving the tar archive to Linux. By the way, to move a single file from Linux to Windows, you don't need Samba, just use WinSCP3 on Windows.
Getting a USB DVD burner to work on any contemporary Linux should be trivial. When I got it working, I just powered down the PC, plugged in the DVD-ROM drive (a Sony drive that Chris Richardson put inside a box that provided power and interface electronics), powered up the DVD and powered up the PC. K3b (my burning software) recognized the DVD immediately. That PC runs the Debian Sarge installed via a Knoppix 3.6 Linux live CD. What Linux distribution and release are you running and what kernel? If you connect a USB flash drive to the PC, is it recognized? [In theory, you need not power it down, but just to simplify debugging, I like to start from a cold power up.]
I recommend creating a tar archive for backup. Remember to backup your journal files too.
I don't have much experience with tapes on UNIX/Linux.
We will cover backup options at the GT.M workshop in Boston. There are multiple choices.

Subject: [Hardhats-members] Linux question: Setting up DVD for backup
I know this question is a bit off-topic for the board.
If you all have a better place for me to ask, just
let me know.
I need a reliable backup solution for my linux server. Here are methods I have explored, unsuccessfully so far. Let me first mention that our office also has a new Windows Server running our billing package. My initial thoughts were to copy my linux data to the Windows server, and then let their backup process save my data.
1. Install Services for Linux (SFU) put out by Windows onto our Windows server. I then created a NFS share. I can view the directory contents of the Windows share from my linux box, but for the life of me I can't get write permission. You have to run a Windows namemapper to map linux users to Windows users, and then give that user write permission. Sounds easy. I can't get it to work. The permission system on NTFS is a bit complex to me.
2. Run a Samba server on my linux box. When I do this, I can see the drive from a Windows laptop, and I might even be able to write to it (I can't remember). But when I try to find the file when browsing from the Windows Server, I can't find it. Not sure if I have to join Windows "domain" to work. This descends into a murky realm for me of ActiveDirectories. Also, I'm not sure if my iptables is filtering out the samba ports etc.
3. Run a Samba client on my linux box. I haven't tried this, but again I worry that I would have to discover how to join the Windows "domain" and be validated.
4. Get scp to work on my Windows server, and scp the needed data up. This would probably work, but I would need to use and 'expect' script to supply the password etc if it is going to be automated. This seems a bit klunky, and will probably be my last resort.
5. Install a DVD writer on my linux box. This is what I am currently trying to do. I successfully installed a new USB 2.0 IO card, and have now plugged the drive in. I'm lost as to what to do now. I have read multiple web sites, and I'm overwhelmed. Right off the bat the install demos talk about possible kernel upgrades etc. It seems that cdrtools is one route to use. I would have to purchase a commercial license. The money is not such an issue, but I would want to be sure it was going to work.
6. Purchase and install tape backup system for the linux box. This may well be a great options, but I have no experience with this.
If anyone has any helpful thoughts or pointers (esp regarding option 5 above), I would be very grateful.
