Microsoft Releases Public Beta of Data Protection 262
Torrey Clark writes "Microsoft has released the public beta of its disk-to-disk backup product, Data Protection Manager. The product is designed to make backups easier than simply backing up to tape. Disk-to-disk backup completes images in significantly less time, meaning much less downtime for systems during backups."

How do you know your backup was made at a point where the file data is stable frOm an apps point of view? Either the app has to be made freeze aware or the app has to be closed.
The snapshot volume you mentioned helps to keep the sever running but any data you backup would be like data copied from a drive from a machine that was powered off without shutting down. You never know just what wasn't in a stable state! Maybe apps need to be written to be backup aware.

Some backup utilities provide capability to take a snapshot and backup that snapshot while the system continues to be used.
One of the features Microsoft is touting in this product is 'moving only the byte-level changes of the file servers' thus eliminating any downtime.

RAID has no advantage in this regard. As I said, I make two backup copies: one on each drive. If there is a hardware failure, there is always a safe copy on the other drive.
I use this method exactly to avoid the hardware problems without the high overhead of a real RAID system. About versioning, well, I have all my codes in VSS and the whole VSS database is also part of what I mirror in backup folders.

A few points (Score:4, Interesting)
Another point is that I do not see where it will support operating systems other that Windows. This is to be expected, but a mature solution should be capable of backing up multiple operating systems as many sites I have seen have a heterogenus computing environment. At my site there are Windows servers but there are also Novell, Linux and SunOS. Is there a solution for those too?
On the other hand, if we're talking about what essentially amounts to "dd" I am sure there could be a handy Knoppix CD created to suit the task in some automated way. It could actually be quite simple in that at a certain time of day (night?) power to a bootable external CD drive is enabled, the system is scheduled to reboot at the same time, it boots from CD, runs "dd" per the scripting in the custom Knoppix where it finishes the job by writing out information to a log file about success or failure and then reboots the computer again. That's just off the top of my head but I am sure that even more elegant schemes could be cooked up. This solution would be effective at creating viable images at a good speed and could even utilize compression along the way.
If Microsoft wants to make a "ghost" backup, then maybe they should just license the technology from Symantec.

My server runs it's own SVN repository and each of my machines can check in it's important files into the tree.
This backup solution is quick and thanks to tools like TortoiseSVN integrates into the desktop for ease of use.
Additional bonus factors are the ability to see the revision history, roll-back, full cross-platform support.
You can also manage multiple copies of the same file to multiple machines should you need to work on them or just want additional resilience.
The real icing of the cake of course is that you can run it over SSL via Apache or over SSH and therefore remotely access your backed-up files from out on the Internet should you suddenly need an invoice or a photograph while sitting in a net cafe in a foreign country.
