Secrets to Good Hard-Drive Hygiene
Creating perfect duplicates of his data allowed my cousin the peace of mind to know that even in a catastrophic failure, he could turn to the mirrored drive or critical files on it and be back to work in minutes.Ever-increasing quantities of private and family data are kept on home computers. But until the last two years, there was a gap between the ever larger hard-disk drives that came with home computers and affordable methods to archive the gigabytes of documents, e-mail messages, home movies and MP3's. That gap has closed as consumer backup software has added features to write archives directly to external hard drives and higher-capacity DVD burners.

Mac OS9 Disk Crash
Ask Metafilter: "I'm a pc guy, but my friend's imac hard-drive has crashed. I managed to salvage the entire drive on a dvd, but otherwise it's been rendered inoperable. So, my question: can I just copy the appropriate folders (keeping directory structure) from the dvd to the new (essentially empty) drive and have everything work as before? Can I do this for specific software, such as outlook (all saved emails lost!) or word? Or do I have to to a manual re-install of all software, export of emails, etc., as any self-respecting pc would require. Mac OS 9.22."

Could Data Recovery Void Your Warranty?
Processor: "Imagine that you just purchased a brand-new server a few months ago and you are running a mission-critical database application on it when one of the hard drives fails. Before you worry about having the hard drive replaced, your primary concern is recovering your critical data. So, you hire a professional data recovery company to extract your data from the crashed drive. When you try to return the hard drive to have it replaced under your warranty, though, the vendor tells you that the warranty is void because the hard drive has been opened. It is a bit of a catch-22: Recovering your vital data is essential, but violating the hardware warranty is not advisable. How can you recover your data without violating the warranty on your hardware?"

SQL Server Disaster Recovery
The first step in developing a solid disaster recovery plan is to develop an idea of what constitutes an acceptable loss for your organization. First, consider the impact of losing data stored in your database. Would you be able to recover from the loss of an hour's worth of data? If you're managing a human resources database, chances are that you could deal with this situation by instructing your personnel to reenter data entered during that period. If you're running the database supporting a financial institution, the loss of an hour's data could bring the instant wrath of clients and industry regulators along with significant monetary losses. Protection against these types of losses is provided by backups of the database and use of transaction logging. We'll discuss these in further detail.Second, consider the loss of access to the database itself. What would be the ultimate result if your end users were not able to access information for an extended period of time. The loss of access to our human resources database would likely result in frustration, but minimal loss to the business. On the other hand, if doctors at a hospital were unable to access test results and laboratory findings in a timely manner it could result in the loss of life or limb. If you find that these issues are a concern in your organization, you may want to consider the use of failover clustering to ensure the continuous availability of your database. This concept will be discussed in a future article.
Once you've determined the level of acceptable loss for your organization and received buy-in from the users you support and your management, it's time to begin developing a strategy to minimize the impact of a catastrophic event on your database. Our first step is to develop a comprehensive backup strategy. We'll discuss this in the next section of this article. Read on!

Recover A Dead Hard Drive Using dd
The Unix program dd is a disk copying util that you can use at the command line in order to make a disk image. It makes a bit-by-bit copy of the drive it's copying, caring nothing about filesystem type, files, or anything else. It's a great way to workaround the need for Norton Ghost.Normally, in order to make a disk image, the disk you're copying from has to be able to spin up and talk -- in other words, it's OK to make a copy if the disk is healthy. But what happens when your disk is becoming a doorstop? As long as it continues to spin, even with physical damage on the drive, dd and Mac OS X will get you out of the fire.
We had a situation recently where a friend sent a disk to us that had hard physical errors on it. It would boot in Windows, but then it would hit one of these scratch marks and just die. We fired up dd, and it started OK, but stopped at the same physical error location -- complaining about a Hard Error.
So the workaround was to designate the dd mode as noerror -- which just slides over the hard stops, and to add the mode sync, which fills the image with nulls at that point. We did it on BSD Unix, but as long as you can get the hard drive attached to your Mac, the command is the same:
dd bs=512 if=/dev/rXX# of=/some_dir/foo.dmg conv=noerror,sync

John Cleese Promotes Computer Backup
AdRants: "While it's about five minutes longer than it needs to be, this video, created in January to promote LiveVault disk data back up, thankfully, features John Cleese who can make anything amusing. In the video, Cleese, taking on the persona of Institute for Backup Trauma Director Dr. Harold Twain Weck (ha, ha, get it?), explains why disk back up is better than tape back up. Particularly humorous is when Cleese goes off on the IT staff explaining that while it might be difficult explaining the need for dick back up to IT types whose offices are festooned with Dilbert comics and stacks of Diet Pepsi cans as if they were the latest Martha Stewart home decor, Cleese's Institute for Backup Trauma has the solution.""

More on Public Beta of Microsoft's Data Protection Manager
Much has been made in various blogs (syndicateONE, Jason Powell, Data Recovery Blog) about this being Microsoft’s foray into the enterprise backup space. I suppose there is some truth to that, although Windows has bundled a rudimentary backup product of one sort or another for quite some time. The reality is that this product does not compete directly with tape backup systems. They solve different problems.A disk-based online backup system allows quick recovery time for files stored online, can be an easier proposition to present an end-user client for "administrator-less restores", and takes disk I/O load off the main fileservers when you do dump to tape (since the tape dump is performed on the mirrored backup copy, not the live fileserver). Disk-based systems do not address the issues of off-site storage for disaster recovery or long term archival (despite what vendors such as NetApp might want you to believe, you cannot just keep buying more and more disks forever).

Data Recovery Market Heats Up
Microsoft Corp. and Veritas Software Corp. appear headed for a showdown as they vie to woo smaller backup and recovery customers with self-service file recovery capabilities and integrated backup and replication technologies.According to Veritas officials at Storage Networking World here last week, the Mountain View, Calif., company next quarter will introduce an offering that marries its backup and replication technologies to enable users to recover data from their desktop at any time.
The disclosure comes on the heels of Microsoft's announcement last week that its Microsoft System Center DPM (Data Protection Manager) disk-based backup product has moved to public beta. The product is set for release in the second half of this year, said Rakesh Narasimhan, general manager of the Enterprise Storage Division for the Redmond, Wash., company.

SyncBackSE
I have True Image 8 and Norton Ghost 9.... They both do fine job in cloning hard drives.. but I can not trust incremental backup and images... I tried about a half dozen time trying to restore files using both software.. absolutely NONE of them was successful... damaged images, files... etc.. I already lost serveral pictures and data... So.. I am looking for file to file backup type software that can incrementally copy files/folders to another networked computer's harddrive without compressing or imaging.... This way... I can always have two exact copies all the time...
It's still too early for a consensus, but SyncBackSE from 2BrightSparks seems to fit the bill. It offers:
- Copy locked and/or open files
- A completely new FTP engine
- 'Fast Backup' option

Introduction to Hard Drive Data Recovery
One of the most important points for any computer user to remember is to always back up your data. As much as personal computing has advanced over the past 20 years, hard drives still fail. Hard Drives are an amazing piece of mechanical engineering, as then spin (sometimes continuously) at around 120 times per second (7200 rpm). These spinning platters are spinning at such high speeds that a small interference whilst in usage can damage the disk in a certain area. There are now fail safe mechanisms in place to prevent critical failures when there is a small amount of physical damage done to the drive, but accidents do happen.When some areas of the disk fail, the hard drive is effectively useless. Cases like this usually require specialists to come and recover any data that might be left. If you have made routine backups of your important data, this would be a great inconvenience to restore and install all the applications and data once more, but still recoverable. If you were unfortunate enough not have any backups (or not recent ones), then you are in trouble. Data Recovery is a very time consuming process, and often quite expensive. Fortunately, there are some data recovery procedures that you can try before having to resort to professionals.

UNIX Backup and Recovery
The Unix file system is reliable and very well-suited to mission-critical applications in which maximum uptime is key. But it's not flawless, and that's where Unix Backup & Recovery comes in. This book details dozens of strategies for keeping Unix systems online. The strategies range from good administration practices that minimize problems to hot-restore techniques that allow you to recover from breaks as seamlessly as possible. The book also contains absolutely inclusive archive techniques that allow you to restore huge databases and file systems from backup media.Unix Backup & Recovery includes a lot of general "recommended practices" advice and lots of scary stories about lost files (and more than a few about heroic system administrators who saved the day, or at least the data). But it gets down to brass tacks too, documenting lots of backup and recovery tools that can make the administrator's job much easier when they're used properly (including cpio, tar, and AMANDA). Coverage of specific systems' backup and recovery issues (including those of Solaris, HP-UX, Oracle, Sybase, and Informix) are invaluable, as is the coverage of techniques for extracting information from ancient, obsolete backup media. The point: read this book before you have a disaster, so you can do everything required to head one off and be ready to deal with problems when they happen.

Microsoft Unveils Public Beta of Data Protection Manager Software
Microsoft on Wednesday unveiled the public beta of its upcoming Microsoft System Center Data Protection Manager application, which is aimed at integrating disk-to-disk and near-continual data protection into its server platforms.The application, known as Data Protection Server when it went into private beta in September, is Microsoft's first entry into disk-based backup and recovery, said Microsoft general manager Rakesh Narasimhan.
DPM cuts the amount of time required for data backups by backing up changes to the data instead of the entire data set, said Narasimhan. It discovers servers through Active Directory, and watches for changes to the data. DPM also allows data snapshots to be taken in order to maintain point-in-time copies.
With customers wanting to backup as much data as possible, anything to speed up the process is welcome news, Knieriemen said. "If someone can provide an application to do this efficiently, customers will be happy," he said.
The biggest question is how Microsoft handles the incremental backups compared to other vendors, said Knieriemen. For instance, he pointed particularly to Melville, NY-based FalconStor, which uses a process called "microscanning" to back data up at the bit-level rather than the block level in order to eliminate bits that contain no data and therefore speed up the backup process and cut space.

If Your Computer Crashes, Don't Panic!
Whenever you have a hard drive problem, TURN OFF THE MACHINE or REMOVE THE DRIVE. Put the disk in a safe place and don�t touch it for the first day while you collect your thoughts. It's very easy to break a drive beyond repair. Resist the urge to open it.
The worst thing you can do after a crash is to panic. Adrenaline can make you do stupid things: like pressing CONTROL-ALT-DELETE when a RAID disk array is rebuilding.

Norton Ghost 2003 Recommended
Hibiscus writing on Google Answers:
I think your best bet is to get a copy of Norton Ghost 2003. Ghost has proven itself to be a fantastic tool time and time again, and the new version is particularly well suited to what you want to do because it now has a Windows interface that doesn't require you to boot the system from a boot disk in order to make backups (though you would still need to use the boot disk to restore a drive image). It has USB support so you can make an image of your drive on to the USB drive you have attached to your system, but it also has full support for network imaging, so if you have a network with multiple machines you could make images on to the drive of another machine. If you aren't backing up huge amounts of data, Ghost also allows you to make images straight to CD or DVD. It allows you to use file compression, so if you have 100GB drives to backup but your external drive isn't quite so large you should still be alright. The new version also supports USB connection to another computer, and supports USB 2.0 to local devices.

A Primer for Disaster Recovery Planning in an IT Environment
Amazon: "If you are an IT person in charge of starting the process, this is an excellent primer that points out all the other areas you have to consider. Hiatt outlines in 100 pages all the elements of research, planning, implementation, and maintenance. She reveals who should be involved in the process and what type of people should maintain the accuracy and currency of the plan. She even gives criteria on how to choose your team. Hiatt references many times throughout the manual when/how/if to use an outside consultant and off-site storage facilities. The following 150+ pages of vendor listings, charts and appendices are extremely helpful. She doesn't just write about planning, but gives you the checklists, plans, and questionnaires to help you get started. It will be much easier for me to use some of her lists and customize for our needs instead of having to write it all from scratch. Plus, she gives a thorough objective listing of vendors which saves me from searching the Internet. As Hiatt recommends, I will continue to research but, her primer will be my main reference. I can now get started without buying expensive software."
