Sorry for double post, I also did want to point out that here
Also, good luck rotating 24TB of removable storage; with a budget of $6500
That $6500 budget went towards both the autoloader, and ~140TB of tape storage-- that is, 5 or so sets of ~24TB each (100 tapes).
Tape is currently $16/TB or so. HDD platters, for the absolute cheapest deals (1TB drives), are around $40/TB-- 3x the price-- and require RAID cards to drive them, as well as hotswap cages. You will not be able to match tape prices for a long, long time, if ever.
No, it's not. It's here and at my offsite location (girlfriends house atm).
Which means you have 2 copies. The tape system I will be setting up this week (~$5000) will give me 20 copies, on LTO4 tapes. Thats 20 entire(ish) backups of our network, with the ability to roll back to any date within the last 3 weeks (our supplemental backup system covers dates further back).
With well less than half that I could build a backup server with 24TB. For that much I could have RAID 1 on the backup server.
Have fun with your error and drive failure rates. 24 drives @ 2TB each (RAID1) means an awful lot of failures each year. Thats also a LOT of arrays to present to your system-- in order to have any reasonable kind of data security, youd need to do 12 separate RAID1 arrays.
Additionally, 24 drives @ 2TB costs between $2400 and $4800, depending on whether you get the "enterprise" quality drives, and a RAID card capable of driving all of them another $1400. Server chassis with backplane and drive cages another $600 or so, and we havent even gotten to the meat of the server yet (unless you want to drive the thing on an Atom patform). You might be able to do it for around $6k, I remember pricing something similar out a year ago, but all of your data is now on one system-- a fire would neatly wipe out 24TB worth of storage, not to mention the Filesystem errors that (so Ive heard) start to creep into systems that large.
Not only that but I can have backup images at, say, 4 hour intervals instantly available at any given moment.
Thats not really what tape is for; we have a supplemental system (crashplan) for that, which IS disk based. Tape is for disaster recovery, not dealing with a trigger happy accountant.
With tape you have to constantly check each and every tape to ensure it's still readable. You have to worry about transporting tapes.
Not much of an issue; LTO4 auto-verifies data, we have enough copies in a regular rotation that one failure is of minor concern, and we have backup software which alerts us to such failures anyways. Transport is of minor concern as well. Ideally, youre supposed to move tape into a fireproof safe, which would mean transport anyways.
With 24 TB you could spend days searching tapes looking for some specific files in a certain state.
We use a backup suite which keeps a catalog of the tapes, and the tapes are barcoded. We tell it we want to roll back to 4/20, for file/etc/sshd/sshd_config, and it says "please insert tape LTO40002A". I go to set A, and insert the tape. Most backup suites will do this.
Worst case, if the catalogs were lost, I could insert the tapes for the proper week, and tell the drive to start inventorying them.
I learned early in my career that going to tape was a terrifying experience. The odds of data lose at that point were always much higher than any level I would consider expectable.
Odd dataloss scenarios are a fact of life. I would much rather have a multitude of copies (ie, 10 or so) that I can roll back to, PARTICULARLY on windows based systems where backup is more complicated than just "cp -aH //RaidBackupPartition".
Have you ever hot swapped a hard drive? What could be more trivial than that.
The problem is that ISNT trivial. Drive letters can change unpredictably on windows and Linux (identifiers, that is) depending on factors such as what other media is present (though GUIDs can alleviate that to some degree...) and in what order it was presented to the system. Harddrives also have a number of other problems, such as all being hooked to the same electrical source and in the same environment, and often from the same batch. Multiple drive failures are much more common than pure statistics would have you believe since they tend to experien
The entire article is garbage. It lists Songbird as a browser (when its really a media player using firefox's Gecko), it implies that other browsers dont have Jumplists on Win7 (hint, Chrome and--i think-- firefox both do), lists "email" as a unique feature of Opera, when Firefox came out of a project that had email et al, Firefox 4s sync is HARDLY unique in an arena with Chrome (and I assume safari and Opera have it as well), and Im pretty sure IE9 has a separate process per tab-- not just chrome.
Seriously, none of these are unique, except perhaps Opera's turbo caching and Chrome's SPDY-- and its a bit too early to tell if SPDY is going to take off.
Thats because this is a war, and if we had had to try every soldier in WW2 before shooting them, we would be dealing with Nazi europe and the Japanese empire right now.
Honestly, I hope noone on the slashdot peanut gallery ever makes General.

It's pretty rare to find undiluted evil in the world, but he sure was it.
I find it sad that you get modded up for this, and I hope you never have an opportunity to see "undiluted evil". The man was a murderer, terrorist, whatever other word you want to apply to him, but he wasnt doing it for killing's sake; and I think that it is hard to call killing in the name of some ideal evil when every country has done so at some point in its history, and over here we celebrate it as the Revolution.
I dont mean to defend Bin Laden; his death was about as necessary as any other in this war, his methods were atrocious, and his ideology destructive. But if you buy into the common wartime propaganda that "the enemy is the devil", then I wonder who else you might not label as pure evil. Want to know why he acted as he did? Just read what he believed.
I would point out that not even Hitler believed himself to be evil; and I think that is a necessary precondition to being "undiluted evil".
Hyperbole much? The poster you quote at least didnt have the benefit of hindsight, but anyone claiming the entire bill of rights has been superceded lacks perspective.
About the most serious BoR amendment that has been ignored, TBQH, is the tenth; and that didnt start recently. You might be able to come up with anecdotes where others were violated once or twice, but youre not going to convince me that by and large the first through 9th amendments no longer apply in this country.
What do you suppose that does for the image of the US as the "great satan"? You think thats the way to make a group of people not hate us? Or do you think that might just increase the number of youth brought up to hate us?
I live in the real world and recognize that if you remove all incentives to produce goods, you get garbage and leeches. Its why communism never works, and it frightens me to see a community of ostensibly intelligent people crusading for an attitude that leads to an economic gutter.
I have used (and still do) use Rsync-- i missed the -H option in your post, but regardless, all of your history is in one place.
The biggest problem I have seen with Rsync is that in directory structures with tens of thousands of tiny files, it takes a VERY long time to search for changes, which can be a problem if you have, for example, database files which need to be taken out of use for backup (the particular database im dealing with doesnt have a "dump" command, as it, itself, is used for remote backup and are gigantic 4GB encrypted files). It is possible that it is just this particular implementation, but I have seen this in several places where rsyncing these backup files takes hours even for 1GB or less of changes over a gbit lan.
As for tape being useless, you can buy, right now, appx 1.5TB of storage at $25 using LTO4 tapes. With that, you get the ability to easily remove and add storage units to your system without awful wonky drivers (ala REV), or dealing with possibly changing drive letters (under windows), or changing device identifiers (under linux-- though as I have only once dealt with tape vs external HDD on linux, there may be a way around this that I am unaware of). Durability wise, HDDs cant hold a candle to tape; tape can be dropped, kicked around, and reused with no issues. Also, good luck rotating 24TB of removable storage; with a budget of $6500, I can easily do that -- a 16slot LTO4 autoloader goes for around $4k, and with the remaining $2500 I can purchase 100 LTO4 tapes and rotate 5x 24TB sets a week if I desire, and store the other weeks in vaults.
Claiming that "tape is obsolete" just makes you look ignorant. There are fortune 500 companies with $1mil tape libraries, and its not because their CTOs are incompetent; its because when dealing with absolutely monstrous quantities of vital information, you would be silly to rely on spinning platters. Additionally, I am not aware of an equivalent to WORM tapes in an HDD form; how do you propose to deal with archival needs?
There is a reason that tape is used a lot-- it is cheap, it is very reliable, and it is trivial to swap out storage.
It doesnt take 6 figures, and if it does and isnt as good as Rsync, you need to find a new line of work.
Any backup solution should include tape, for a very simple reason-- you end up with multiple offline copies of data at about $25 per terabyte. Your backup solution sounds like it gets knocked out if someone introduces bogus data into your system; once the backup occurs, it overwrites all your good backups.
A good backup system isnt even that expensive; about $4000 will get you an LTO4 autoloader with a full complement of tapes, and another $500 gets you a good disk-based system.
Going through 3rd party servers means plenty of risk of exploits
You already go through 3rd parties, its called the "internet", and there is a solution-- encryption. Which is why all BES communications are 3DES or AES encrypted.
If there are ever exploits for AES, then Blackberries are the LEAST of our concerns.
Android is in an entirely seperate market than Blackberry. Basically, if the user is choosing his phone, he will get an iPhone or Android. If corporate IT is choosing it, they will choose Blackberry if they have any sense whatsoever.
Unless of course you like dealing with pushing trusted certs, and changed windows / email passwords, and reconfiguring ActiveSync when your topology changes, and all the rest.
My sense is that they jumped the shark by failing to either make BES free
BES IS free now. Its called Blackberry Express, and it works just as well as the old BES. I have deployed it twice now, and it works perfectly-- better, in fact, than ActiveSync.
and blackberry's current flagship devices are out-dated, at best,
That has been the case for YEARS. You dont buy a Blackberry for personal use, or for its Multimedia capabilities (or if you do, youre daft); you buy it for its slick email, calendaring, and contacts integration, and for their incredible manageability.

How your post gets modded will say an awful lot about Slashdot, and its ability to deal with differing opinions in a rational way.

Im not sure I get your point. Are you arguing that Hotels deserve to be stolen from?
The bug hunters seem happy to do it. Why do you feel the need to be outraged on their behalf?
The fact that Blackberries can hold a charge through an entire day of talking surely counts for something?
Anyways, everyone knows that corporate is where blackberries shine. Im sure theyd love to get more customers, but it is primarily a business phone.
There is no reason to get a RIM device over Droid or IOS and many reasons to not get one.
