zfs send and receive are not good to use in enterprise solutions for the reasons stated here: http://www.solarisinternals.com/wiki/index.php/ZFS_Best_Practices_Guide#ZFS_Backup_.2F_Restore_Recommendations
Instead, do what the parent poster said... once you have your snapshot, tar the directory and send it to tape or to your remote system. Need to restore 1 file? No problem. What if part of the snapshot is corrupt? You should still be able to get at most of the data. The whole snap is not lost.
The Herman Miller Aeron is my choice. Strong enough to take my abuse (and I'm tough on furniture). Comfortable enough to sit in for hours. The aesthetics are extremely nice IMHO.
I built my own home file server. Total cost was around $650. I used OpenSolaris (solaris nevada b75), and created a zfs mirror. Now I have things like snapshots, compression, quotas, and reservations. It took only a few minutes to create the mirror once I had the machine put together and the OS loaded.

Well, in our case, we're developing for 1 linux distro, and we still run into problems with incompatibilities between libgcc, libstdc++, and our application.
You sound really bitter about Solaris. I dunno what's up with that. Everyone I know that's worked with solaris for a fair amount of time really likes it. I've been developing on it for about 10, so maybe I'm biased.
How can you dismiss dtrace as irrelevant? My whole point is that it is relevant and that it's one interesting feature in Solaris 10. I was just hoping you could point me to a better tracing program than strace. I really didn't expect you to find one better than dtrace.
Actually, dtrace wasn't dreamt up by a sun engineer because he needed to justify his existence. I've read the story, and it was developed because of user demand. They got lots of advice from Solaris users not at Sun, including a well known sys admin named Jarod Jensen. I believe Dtrace was developed by Bryan Cantrill and Adam Leventhal at Sun. Here is a PDF he put together called dtrace boot camp that gives lots of exercises to demonstrate the kinds of things you can do with it: http://learningsolaris.com/docs/dtrace_course.2005 .8.18.pdf
You can ship your own libstdc++, but often libstdc++ is incomptabile with the customers installed copy of libgcc.
Please point me to a kernel trace toolkit that can replace the level of functionality found in DTrace. I'm skeptical. If such a tool exists, I'd like to know more about it.
I don't work for sun, nor have I ever. But I do work with both Linux and Solaris, and I have to disagree that ZFS is the only thing that's at all interesting in Solaris.
How about: 1. DTrace 2. Zones/Containers 3. User and process rights management (way better than sudo, IMHO) 4. How about binary compatibility? I can't stress how hard it is to deliver application binaries on Linux because of incompatibilities between libstdc++.so and libc.so -- and that's on different versions of the same distribution. Try delivering those binaries to a different distro for a real nightmare. This is _never_ a problem on Solaris. 5. Stability -- Linux is stable, but I have to say that Solaris is even more so. The file systems on our linux machines are much more susceptible to corruption during power outage than UFS or ZFS on Solaris. 6. SMF (Services Management Framework)
A lot of people don't realize how far Solaris on x86 has come in the last 3 years. It's the real deal. I encourage you to find out more, and see for yourself.
1. The mouse never billed itself as being bluetooth. Also, many existing macs don't have bluetooth builtin. Hardly any desktops do, and the ibooks only recently came with bluetooth as a factory default. So if it were bluetooth, a large percentage of users would be left out.
2. Who wants an excessively long cord that adds to that rats nest of wires under your desk? The short cord is ideal for Mac users because the mac keyboard has usb inputs to accept your mouse.
One nice thing about OS X is the list of stuff I don't have to install.
Top 10 items that I am glad are already installed out of the box for me:

In OS X, the native windowing system is called Aqua. It's not just a fancy skin on running on top of X-windows. Aqua has some great features. It allows the video chip to do some of the render processing (and that frees up clock cycles on your CPU). It has anti-aliased fonts and in general looks very sharp. aqua In addition to aqua, OS X comes with an X Server that lets you run programs written for X windows. These windows look clunky and ugly compared to the native GUI.
Apple readily admits that they don't intend to make money from this. from an MSNBC article:
"But Jobs contends that in the long run the competition will boil down to Apple and Microsoft. "Between the license fees and the credit-card charges, there's no money in online music," he says. For Apple, the payoff comes in selling the iPod players that work hand in hand with the store: more than a million have been sold, and in the last quarter, Apple moved 336,000 units."

Well, rather than refute and drag this on, I'll just agree to disagree and leave it at that.

another new server called the X4600???
It can be configured with 8 Dual-core AMD Opteron chips, each running at 2.6 GHZ.
WOW!

Way to go Sun. Looking at the pictures, it seems that it has dual opterons. Awesome.

doh!
what sounded silly was my first sentence.
Mean "That sounds sort of silly though, doesn't it?"
That's sort of silly though, doesn't it? The only one that seems to win with the "embrace and extend" is the guy with the monopoly.
I'm using Preview on 10.3, and it most definitely does have search capability.

So many people on here are mocking "Dtrace"... read parent's link on the usenet posting. The tool is way cool.
Supposedly the article just scratches the surface on what Dtrace is capable of...
