In the Event of a Data Loss

April 13th, 2010

After you’ve been in this business long enough, you get used to the panicked calls. Somebody you know has lost all or most of their mission-critical data. Or their e-mail server has gone down and their entire business lived in their e-mail. The details always differ, but the result is the same. Everything is gone, nothing was backed up. All is lost.

At least most of the time everything is lost. From time to time the company involved actually had backups, but they weren’t really stored like they should have been, and there was a fire or some other disaster. Sometimes a good data recovery service can find most of what’s missing, and get the company up and running in a few days. But those situations are more the exception than the rule.

A more normal call came to me this week. A company I’ve worked with had mysteriously lost its e-mail data. One of the principals of the company was frantic. What could they do? I asked the questions I always ask. No, the e-mail server wasn’t backed up. Likewise, there was no automatic mirroring, no off-site copy, and the server’s hard disk was just a disk with no RAID configuration. Wasn’t there something I could do?

“Sorry,” was the only thing I said. In the past I’d already pointed out the need for backups, provisions for data recovery, all of the other things that people who run data centers do as a matter of course. The fact that a company didn’t think of itself as running a data center didn’t lessen the need to protect their information. Of course, even large companies are playing IT roulette with their data these days.

But at least a formal data center probably increases the need for a company to take steps to protect its data. Without a real data center, the servers are less likely to be protected and the data more likely to be at risk. All those best practices that people learn when they run data centers are probably being ignored.

So, short of doing the smart thing and actually building a data center, even if it’s a small one, at least you can protect your data. Perhaps the easiest means of protecting the data your company needs to stay in business is to sign up for data backup in the cloud. There are services that provide high-quality, highly protected sites for your company data at low prices.

Companies such as Mozy and Carbonite can provide reliable, inexpensive off-site backups of your critical data in real time. What’s more, if your office is destroyed due to a fire or something, your data is still safe, and you can bring your business back to life from another location.

Why am I telling you this? It’s simple. I don’t do data recovery. I’m not the guy to call when you lose your e-mail server. If you care about your business, then it’s up to you to be responsible and make provisions to protect your mission critical data. The most you’re likely to get from me is a sincere, but only somewhat heartfelt, “Sorry.”

The hard disk in a computer stores your important and privacy data, and boots the Operating System. As you can see, hard disk has larger capacity and higher performance than most other storage devices, but it is so fragile that even slightly shock can lead data loss.

In daily life, you may encounter the disaster caused by incorrect manipulation or virus attack, which will let you be too deep for tears…

So, in order to avoid such things to happen (again), it is truly necessary to install at least one data recovery software solution stand by.

 

NOTICE: Before launching the processes of data recovery, you should protect the target partition and avoid ANY write operations on it, if it occurs in system partition, you must install the data recovery software to other places instead of default path.

  • USEFUL FREEWARE

Do you remember Recuva in last post  Top 3 Free Photo Recovery Software Programs for Digital Camera and Memory Card ? It is tiny and free, you can launch it on your thumb drive.

Download the portable version and extract the pack to a safe place, then launch the program Recuva.exe, click “Cancel” in “Wizard” window.

Recuva

Select the target partition for data recovery, click “Scan”, wait for a while and you can see the results. The “Actions” tab in “Options” also provides functions to “deep scan” and “recover damaged or reformatted disks”.

Not only Recuva, but also Pandora Recovery provides functions for data recovery.

Pandora Recovery

Pandora Recovery

Pandora Recovery will scan your hard drive and build an index of existing and deleted files and directories (folders) on any logical drive of your computer with supported file format. Once the scanning is complete you have full control over which files to recover and what destination to recover them to. It’s completely free.

If you deleted an important partition by mistake, you can refer to the article How to Restore missing partition, or try the free Paragon Rescue Kit Express provided by well-known Paragon Software Group, which delivers solutions for hard disk management, partitioning, drive backup.

  • EXCELLENT SHAREWARE

While the utilities mentioned above are free, they have more or less limitations in functions. If you are not satisfied with the recovery quality, experiencing difficulties, or even want more powerful abilities for data recovery, you can try some shareware, and pay for it as you like.

R-Studio is a data recovery solution for recovery files from FAT12/16/32/exFAT, NTFS, NTFS5 (created or updated by Windows 2000/XP/2003/Vista/2008/Win7), HFS/HFS+ (Macintosh), Little and Big Endian variants of UFS1/UFS2 (FreeBSD/OpenBSD/NetBSD/Solaris) and Ext2/Ext3/Ext4 FS (Linux) partitions. It functions on local and network disks, even if such partitions are formatted, damaged or deleted. Flexible parameter settings give you absolute control over data recovery. In addition, R-Studio also includes an advanced RAID reconstruction module.

R-Studio has the most functions among all data recovery software mentioned here, but it is a little difficult to start using that powerful tool.

GetDataBack

GetDataBack

GetDataBack will recover your data if the hard drive’s partition table, boot record, FAT/MFT or root directory are lost or damaged, data was lost due to a virus attack, the drive was formatted, fdisk has been run, a power failure has caused a system crash, files were lost due to a software failure, files were accidentally deleted. GetDataBack can even recover your data when the drive is no longer recognized by Windows. It can likewise be used even if all directory information – not just the root directory- is missing.

Recover My Files

Recover My Files

Similar to GetDataBack, Recover My Files is fast and easy. No technical or data recovery software skills are required to undelete files. With a deleted file the data content of the file is rarely destroyed. Even if Windows file reference information has been destroyed, Recover My Files scans the data at a low level to locate “Lost Files” by their internal file structure.
