WHS As A Backup Suite, Cont
As for restoring data, WHS comes with two options. The first is the traditional per-file restore, which can only be handled by a client. When a user/client wants to restore a file, they will pick the date/backup from which they want to restore the file, at which point the connector software will mount a dynamically-generated volume that is the contents of the client as of that backup. At this point the user can copy over files from the backup volume to their hard drive.
For a more complete restore, such as in the case of a catastrophic failure or those looking to use WHS as an image backup server, WHS ships with a live-restore CD. When the restore CD is inserted into a computer, the affected machine can connect to the WHS server and select a whole backup to restore. Since the operating system is included in the backup, it is also included in the restore, returning the machine to the same state it was in as of the backup. This process does however wipe the client's hard drive in the process, so it's not something that can be used leisurely. Power users that will be using it as a way to image and restore machines will especially appreciate the ability to restore to volumes of arbitrary size, and while Microsoft isn't pushing the imaging ability hard, it's one the best features of WHS.
There are a few caveats with the backup features of WHS that bear mentioning however. First and foremost only machines running Windows XP SP2 or Windows Vista x86 can be backed up. Older versions of Windows are not supported, and more surprisingly x64 versions of Windows are not supported. The WHS development team has cited the need to write drivers for the backup/restore abilities as the reason for the latter limitation, as they did not have the time to write a good set of drivers for both x86 and x64, so x64 support is not included for now. Unfortunately we don't have a good idea when such support will arrive; the development team for WHS is working on writing a version of the software for x64, but they are not saying when it might be ready.
Hardware constraints also need to be considered. Backups are transfer intensive, so anything less than a gigabit Ethernet link will cause the network to be the bottleneck. This is especially problematic for wireless links, which under 802.11g are practically capped to less than 6MB/sec (and realistically top out at under 4MB/sec), a fraction of the transfer rate of a hard drive. Microsoft highly recommends at least a 100Mb Ethernet link (forgoing a recommendation for wireless entirely), but wireless will work at the cost of being especially slow when WHS needs to do another full backup because it is ready to throw out the old one.
Last, there is the issue of doing backups at convenient times. A machine needs to be fully-on to be backed up, and WHS only has a limited ability to deal with AWOL machines and deal with machines that aren't currently on; it (or rather the connector) can wake up sleeping computers, but does not have a wake-on-LAN feature for waking up computers that are shut off entirely. An add-on exists that can handle this, but the only reliable way of backing up a machine at night is to leave it on or put it to sleep instead of turning it off. Sleeping however can be more problematic on an enthusiast computer than an OEM-built one.
With that said, it's very clear that Microsoft has put a lot of thought and their best technologies into the backup feature of WHS. Although this isn't a round up where we can adequately and fairly compare all the major backup software suites, we will say that we're very impressed with what WHS can do here. The backup features alone can sell WHS if the price is right as is the number of machines.

I really impressed by you responses.You might be right about set up mess and definitely right about need to read few pages in order to try something not microsoft.
It is a free world when you choose your platform, but far away of being free when you choose proprietary one.
while you talking, most of you did not try any *nix in last years.
If my parents, cousins and the rest of close persons were able to use it without calling me twice a week each, for some kind of support as they did in XP time and not to reinstall XP once a year for each box, then it's really indicates user friendliness and stability of non MS OSes.
And by the way, you can by preinstalled and configured Linux box from Dell, HP or Lenovo (not to mention other smaller OEM's) and not to waste your time on installation.
As for the growing take next example:
Online defragmentation
Although the extent based nature of XFS and the delayed allocation strategy it used significantly improves the file system's resistance to fragmentation problems, XFS provides a filesystem defragmentation utility (xfs_fsr, short for XFS filesystem reorganizer) that can defragment a mounted and active XFS filesystem. Note that xfs_fsr is usually part of xfsdump package, not xfsprogs.
Online resizing
XFS provides the xfs_growfs utility to perform online resizing of XFS file systems. XFS filesystems can be grown provided there is remaining unallocated space on the device holding the filesystem. This feature is typically used in conjunction with volume management, as otherwise the partition holding the filesystem will need enlarging separately.

there is no such thing as perfect software (OS is one of this). but there is definitely better and worse .

You are so wrong, it is geared towards everyone. The software it uses has been proven to be VERY reliable. As stated in the very article you are posting about. NTFS is also very reliable.Of coruse grandma won't care for it, but I already know many people who are getting it based on how easy it is to use. Even businesses are getting it i know of because of ease of backup it provides plus not having to hire outside help to set it up.
The fact that you completely don't understand the HOME part of the server is mind boggling.

I understand one thing.Can not find justification to pay for license when it can be done completely without cost.
NTFS compared to journalized file systems is bad in term of data reliability, performance etc.
Can not find reason to pay for new computer while very old one can do the job perfectly.
(P 4, 1.5GHz, 1GB RDRAM, ~1.3TB storage perfectly doing the job of File, Backup, Mail, DNS, FTP, Net Boot server all in one with uptime of 6 month (every 6 month i clean the dust inside my computers) where the HD and SATA PCI cards are only things that i needed to buy. Just for the price of license, you can add at least 500 GB of additional storage.
All you need is RTFM how to set up linux box. Easy way, binary distribution will take 2-5 hours to set up all this. Advanced way, source distribution (such as Gentoo) can take few days to compile (all done automatically and your attention needed not more then in ordinary installation) . took me 3 days to complete it on p2 400MHz laptop with 186 MB ram. which is now able to a nice balcony terminal with internet access and ability to view movies (that was impossible under very cut and optimized XP, maximum 6-10 fps for movies, and very close to impossible in binary linux. )etc.
I don't tell to replace your desktop (since i have dual boot on main computer to be able play some very new games that not yet supported in linux), but if you want stable server, working without your attention, and you don't need to wonder what to do with slow downs, dirty regestry etc after year (not to mention viruses etc). Not to mention the easiness of move the system to new hardware (when you want it), transfer the disks and power up.
I can continue and explain another 100 reasons why this WHS is useless, but the buttom line will be the Subject. This is another MS way to squeeze few mor bucks from you, and may be to grant need for MCSE and MCSA guys that will extra cost for your small business friends.
As for the HOME part -- i spent 2 years of my life working at tech support of ADSL provider. I know exactly what is average HOME users with a lot of computers. They will call some technician to do the setup and to fix their problems. exactly what they doing when they need to reinstall OS or clean up the mess. For advanced users (like you if you spending your time on this site) will be much more cost, time, and performance effective not to use it.

What you've just said is one of the most insanely idiotic things I have ever heard. At no point in your rambling, incoherent response were you even close to anything that could be considered a rational thought. Everyone in this room is now dumber for having listened to it. I award you no points, and may God have mercy on your soul.neogodless - Wednesday, September 5, 2007 - link
What makes me sad is that I did actually read it all the way through.Also... I don't understand why people argue so violently against some things.
I was able to try out the RC, others can download a 120 trial when it is available... you can find out for yourself. And you can also download Linux and try it. See which one is easier to set up.
Personally, I consider myself pretty advanced, and I tried Ubuntu 7.04 and still felt pretty lost when I wanted to do things. Yes, I'm sure I could learn it but time is valuable... I can spend half an hour setting up WHS... like I did, and just forget about it... nothing to learn, no need to tear my hair out!

i agree that was an big rant i my self fix pcs all day and it takes me more then an hr ot day to do things on linux that should only take 6 clicks or some command line tool to do it as welllinux software makers do not think to much about useablty for any one who is not an linux guru
try and play an Mp3 or an stream, tell me how long that takes you to play it (i hate to try and play an xvid file)
i tryed to use it lots of times my self just get stuck at simple things that should be simple that it i should not have to type {chmod 2883 -d -w -u \file\sfd} (made up as i cant find any help for setting the securty of files for that command any more)

How long does it take to set up a "without cost" system? Now multiply that by $50/hour which I bill. And you still won't have single instance storage.tynopik - Wednesday, September 5, 2007 - link
> Can not find justification to pay for license when it can be done completely without cost.oh really?
please tell me where i can find a backup system as flexible and powerful as this at no cost
- autocombine all physical disks into 1 volume
- disks can be any size
- disks can be added or removed at will
- yet still have physical redundancy of files on different drives
- automatically save single instance of identical files/blocks to reduce space wastage
- automatically preserve previous versions
- do live imaging of windows systems that can then be restored from bare metal with just a boot cd and a network connection
sure parts of it can be duplicated for free, but do tell how you would setup something that does ALL that

WHS lacks the drivers to run tuner cards and other media center paraphernalia, so it can't act as a media center. However, its hardware requirements are quite standard - disk andnetwork card - so it should be feasible to run it under virtualization on your MCE box.
Ideally, you'd want to give it its own disks, rather than having the virtual machine's disks map to files on the host machine, but that wouldn't be mandatory.
