Data Recovery - Your Next Option To Safeguarding Information

Data Recovery - Your Next Option To Safeguarding Information

The realization about the need to prepare for safeguarding crucial data on your hard disk may come a little too late when the computer or the hard disk has crashed. Data loss could mean, for a small business, going out of business unfortunately, sometimes permanently. Rebuilding years of data is out of question. It is pertinent to know the whys and hows of data loss in order to understand data recovery better.Important Causes of Data LossWhat you hoped will not occur, perhaps because of no reason, could always hit you hardest unless you are safeguarded against them. Computer running slowly could be because of spyware scrupulously installed could be working behind screens to destroy or transmit data to their masters eventually causing hard disk to crash. Others like electric storms, power surges, mechanical failures, fires & floods and user errors (sometimes in disregard of warnings) could affect your computer without any or sufficient warning.You could also loose data because of sudden but unintended deleting of files or programs. Accidental disk format, virus attack, partition loss are some more causes for data loss.Data ProtectionData protection is the best policy than ruing over the loss. You can make use of trusted data backup software which automatically backup your data regularly, if you cant do it yourself manually. Keeping backup of backups will safeguard you against the worst eventualities, too. Turn off your computer immediately as you hear strange noises like creaking run of hard disk. It is also wise to unplug power cords, modem and telephone cables when you are going out of home or office for a long time.Data RecoveryThe first thing you need to understand when dealing with "data recovery" is not loosing cool. Never act in haste and dont attempt data recovery yourself unless you are an old hat at that. Call for professional help from your area and who you know.Data recovery software does a neat job in most of the cases. There are quite a few reliable softwares available, no matter what platform your computer operates on. Data recovery softwares are available for Mac, Windows, Linux, and so on. Dont attempt to use the software yourself out of gut feeling. If you must, check for user friendly personal packages.An average company in US alone spends anywhere between $100,000 and $1 million in total for desktop-oriented disasters. This should more than emphasize the need for data safety and disk recovery.

Know What You're Dealing With: Essential Information You Must Know Before Paying for Data Recovery

Know What You

Know what you're dealing with
The world of data recovery is a big mystery for most consumers and even some IT professionals. This is largely because hard drives themselves are complex devices and their technological specifics are not generally well known. Data recovery companies thrive on their customers' lack of information and often get away with charging obscene rates for any recovery, regardless of complexity. I hope this article will be a helpful resource for consumers and professionals alike. I provide some basic information about "data recovery" by shedding some light on how hard drives work, how they can fail, what are the chances of successful recovery and how much the user can expect to pay. This information will enable the user to make an informed decision when choosing a data recovery company.

A bit about Hard Drives

A computer hard drive stores data on metal oxide platters which spin up to 10000 revolutions per minute. An actuator arm contains the 'head' which reads and writes the data in the form of magnetic charges one millionth of an inch above the surface. Any given drive can have multiple read and write heads and each head can 'crash' independently. A head crash occurs when the read/write head comes in contact with the platters of the disk (more on head crashes below). As manufacturers strive to cram more space on hard drives without increasing their physical size, the data gets written increasingly closer together, making for very difficult recovery should one or more heads crash. The brain of the hard drive is its controller board and this is unique for each individual hard drive. One other detail worth a mention is the service track of a hard drive. This is an area located on the outer part of the disk platter and it contains the drive's firmware zone. The firmware of a hard drive is the information used by the computer to communicate correctly with the drive. These are the main components that make a hard drive work, now let's talk about what can go wrong.

There are many ways in which a hard disk can fail

Hard drives are extremely fragile and can suffer failures in many different ways, leading to a loss of data. The five most common types of drive failures are: logical errors, mechanical failure, electronic failure, firmware corruption, and bad sectors, or any combination these. Least severe of these is usually data loss due to logical errors.

Logical errors are often the simplest and sometimes the most difficult problems to deal with when recovering data. They can range from an invalid entry in a file allocation table, a simple problem that needs little work; to severe issues such as the corruption or loss of the entire file system. Logical errors can be spotted when files become inaccessible, there is a delay in starting up the computer, and programs do not run properly. Logical errors are often seen as simple because there is nothing wrong with the physical drive leading users to try recovering it themselves by using third party software. This is quite risky, however, as running such software on a damaged drive can result in total loss of data. The most effective way to prevent logical errors on your hard drive is to regularly use the Disk Defragmentation tool in your operating system. For more comprehensive information on preventing data loss, visit the tips section of our website.

Recovering a drive with logical errors can be simple and quick, however if the problem requires manual bit-by-bit reconstruction of the data, it can also be quite complex and time consuming. Normally, logical errors are in the lower end of the price range as they do not require manual disassembly of the drive, however there are cases when logical failures end up in the higher end of the price range. The bottom line with logical errors is the sooner they are caught and the less a user tampers with the drive, the better the chances for a quick and thorough recovery.

Mechanical failures are often much more serious than any other failure and frequently lead to a partial or even total loss of data. The most common type of mechanical failure is a head crash, which is when the read/write head comes in contact with the disk platter. Head crashes can be caused by a variety of reasons, including physical shock, static electricity, power surges, and mechanical read/write failure. Mechanical failures are detected by a constant clicking or grinding noise coming from the drive. If you suspect mechanical failure, you must immediately shut down your computer and call a data recovery company for advice.

Mechanical failures are usually the most severe and most challenging to recover from. All mechanical failures require physical disassembly of the drive. The replacement of a read/write head is one of the most complex and costly procedures that can be performed by a data recovery engineer, especially with larger capacity drives. The chances of recovery depend entirely on how much damage the drive has sustained, however they can be quite good. A crashed head does not mean that all your data is lost! Once again, the sooner you catch a mechanical problem and turn off your drive, the more of your precious data is likely to be rescued.

Electronic failures are most common after a power surge or due to some other electric problem, and the most common type is control board failure. A power surge can knock out the control board, making the drive undetectable in the BIOS. Because each drive is fitted with a unique control board, recovery of this type is relatively complex. However, the good news is that normally once the control board issue is fixed, the data is usually 100% recoverable.

Recovering a drive that has suffered from an electronic failure can be time consuming, mainly because the specific problem takes some time to diagnose. Once diagnosed, though, the recovery is usually not tremendously complex and would probably land in the mid-range in terms of price. Most of the time, we are able to achieve a 100% recovery from drives that have suffered an electronic failure.

Firmware corruption is caused by logical problems or physical damage to the firmware zone on the disk platter. When the firmware becomes corrupt, the computer is often unable to properly communicate with the hard drive, and drive is not recognized in the BIOS. Fortunately, when the drive fails due to firmware corruption, the data is usually fully recoverable once the drive has been repaired.

Recovering a drive that has suffered from Firmware corruption is possible with the use of our proprietary technology. Because the firmware information is isolated on the outer rim of the disk, most of the data can be recovered successfully. The complexity of recovering a drive that has suffered from firmware corruption depends on the amount of damage suffered by the service track on the disk's platter. Expect the cost of this type of recovery to be in the mid- to high-price range.

Bad sectors are a common fate of all hard drives.

Eventually, all drives develop areas that are no longer functional and when this happens, they are isolated by the operating system. Bad sectors are very much like bumps in the road, areas which are avoided by the read/write head and which are no longer accessible to the user. If mission critical data exists on the drive, we recommend to backup as soon as possible, as the formation of bad sectors often indicates the impending demise of the drive. Finally, and most importantly, do NOT under any circumstances run the ScanDisk or Chckdisk utilities when data becomes inaccessible. These utilities are designed to fix only file system errors and not any other types of errors, so if your hard drive has suffered from bad sectors, these utilities only make things worse.

Bad sectors are accessible

We are able to recover drives with bad sectors using our proprietary mirroring technology. The process often involves manual mirroring bit-by-bit, which can be time consuming. The price of this type of recovery will generally be in the mid-range of the pricing schedule.

I hope the above explanations are of some use to all computer users. The basic fact is that data loss happens to everyone. Every hard drive crashes, and often when you least expect it to. Backup is essential for end-users and business users alike, and there are many excellent ways to back up your data. But if you've lost data, attempt to understand the problem before calling a data recovery company. Be informed, save your money, get your data back.

XCACLS, SUNINACL, And Other Permissions Security Recovery Tools

XCACLS, SUNINACL, And Other Permissions Security Recovery Tools

You Have 50GB Of Data To Move Along With Permissions Security----------------------------This article is about several tools that can save a Windows administrators you know what in the event of a large scale permissions security problem.Here is a fictional scenario we can use to illustrate the use of the XCACLS tool. We need to move or copy 50GB worth of data that is comprised of several thousand directories containing hundreds of thousands of small files from one storage system to another. These systems happen to part of a Windows 2000 Domain and permissions are quite granular in definition. We start the replication of that data using a favorite replication or synchronization tool and walk away for the evening. When we return the next day, everything has copied and all looks well. That is until you try to access the data.The Data Is Copied, But I Cannot Access It: Permissions Security Problem--------------------------------------------------What you did not know, until just now, is that the root directory of the drive that you copied the data to had the wrong permissions assigned to it. In addition, inheritance was configured such that any data that is placed on the drive is over written with the permissions of the root directory. In this case, it was an old account that no longer existed. Believe it or not, that can happen, and system administrators will know what I am talking about. Now you are left with trying to figure out what to do. Do I format the new drive, change the permissions and inheritance on the root directory so they are correct and start all over again? Do I make the changes on the root drive so they have the correct permissions and wait hours upon hours for the permissions to propagate? No, there is another, very fast way of resolving this issue with XCACLS or another tool called SUBINACL. XCALCS Quickly Resets Permissions On Directories And Files----------------------------Becasue I have limited space in this article, I am going to use XCACLS as the tool to correct this problem. However, in complex permissions structures, you will most likely want to use SUBINACL to fix the issue. I will talk about SUBINACL briefly at the end of the article. XCACLS as a very fast tool that can set, remove, add, and change permissions on files and directories. For intance, the following command replaces all existing access rights and accounts with that of "dmiller" on the file "file.txt" with read-only access: "xcalcs file.txt /Y /T /G domain\dmiller:r". Although that is pretty easy and helpful, what about changing all my directories and files, which I have thousands of, to allow the domain\dmiller account to have full access? To do this in a very fast fashion you could execute the following from the root directory of the drive: "for /d %g IN (*.*) DO xcacls "%g" /Y /T /G domain\dmiller:f". This will go through every directory, subdirectory, and file and replace the current permissions with dmiller having full access to the object. You'll notice I put "" around the %g in the example. This is not required, but if you have directories that have names with spaces in them you will need to have the "".What Other Ways Can I Use XCACLS To Change Security Permissions----------------------------------------------------------To give you a few additional handy examples of how you can use this tool take a look at the follow command prompt methods for replacing, updating and removing accounts and permissions from large numbers of directories and files.The following command replaces all existing access rights an accounts with that of dmiller with read only access rights: for /d %g IN (*.*) DO xcacls "%g" /Y /T /G domain\dmiller:rThe following command does not replace existing account permissions, instead, it adds the account, in the example the local admin account, with read only permissions: for /d %g IN (*.*) DO xcacls "%g" /Y /E /T /G administrator:rThe following command removes the account "administrator" permissions from all directories, files, and subdirectories: for /d %g IN (*.*) DO xcacls "%g" /Y /E /T /R administratorThis command should update all the directories and their contents to allow Domain Admins full access: for /d %g IN (*.*) DO xcacls "%g" /Y /T /G "Domain Admins:f"I did a test on my XP Pro workstation and was able to change the permissions on approximately 10000 directories and files in less 1 minute. On one of my servers I was able to achieve a 500% increase in speed. It is blazingly fast. SUBINACL Is More Complex But Man Can It Really Save The Day-----------------------------------------------I cannot go into specifics about this tool in this article but I will tell you what it can do. And again, it does it very very fast. Using the same scenario as above, let's say that you had to fix the permissions on thousands of home directories. With SUBINACL, you can actually go to the original directories and files, use the tool to create what is called a "play file", a text file that contains the right account and permissions from the source files, then use that same file to tell SUBINACL to fix the permissions on the target storage system, the one with the screwed up permissions. It's quite the life saver if you ever find yourself in the type of predicament.Also check out "CACLS". This command is inherent to Windows XP Professional. Conclusion----------These tools are contained in the Windows 2000 and 2003 server resource tool kit, however several of them also exist native to the Windows XP environment. Check them out if you don't already know about them. Even if you have no use for them right now it may save you hours of hard work and stress in the event of a future permissions problem.You may reprint or publish this article free of charge as long as the bylines are included.

Computer Data Backups: Test Now or Cry Later

If you're like most small business owners, your computer data backups are one of those things that you rarely pay attention to. Computer data backups are kind of like flossing your teeth and eating low-fat, high-fiber foods everyone knows what they're supposed to do but how many REALLY do these things religiously?!?Unfortunately when it comes to your "computer data backups" however, complacency can be very dangerous. Of course, it's always a good idea to have a local computer service company that you can rely on for advice on selecting and maintaining your computer data backups. But, unless you're prepared to put a full-time PC support person on your company's payroll, it's really important that you get some basic understanding of the major issues with computer data backups.So here's a compilation of some really crucial tips on computer data backups that I've put together, after nearly 15 years of helping small businesses protect their valuable computer data files. Test your computer data backups regularly and monitor their log files. To be effective, computer data backups must be highly automated to ensure that jobs are launched consistently and correctly, but your computer data backup system also needs to be watched over diligently to make sure it continues to function reliably. Unfortunately, monitoring the computer data backup system generally isn't a priority until something goes wrong. By then it's too late. Like the article title says, Test Now or Cry Later!People have a strong tendency with a computer data backup system to set it and forget it. Automation clearly has many benefits, but a totally hands-off approach can be very dangerous if no one is overseeing your computer data backup process. Test and Then Test Again: VERY Important with Computer Data Backup SystemsWith any newly installed computer data backup system, don't assume everything works correctly right out of the box. Even more important, don't take for granted that your backup system will continue working indefinitely. You need periodically to restore some folders and files from your backup media to validate that your computer data backup system still works.If your automated computer data backup routine is configured to include a verify run with each backup job, testing a sample restore job monthly should be adequate. However, if you have an extremely low tolerance for risk, you may want to simulate a sample restore job once a week.The Hazard of Moving Parts and Open Design with Computer Backup SystemsWhy do you need to take these precautions if you're purchasing a reliable, business-class computer data backup system to start with? Typically, a tape drive or other backup device is one of the few components in a PC or server that still have moving parts.As a result, it's more prone to mechanical failure. In addition, because a backup device generally is open, as opposed to the sealed design of a hard drive, it's easy for the inside of the computer data backup system device to attract a significant dust buildup in a relatively short period of time.Sample Restore Jobs and Cleaning Tape Heads of Computer Data Backup SystemsTesting a tape for a sample restore job is also a great time to clean the heads of the backup drive if your backup system requires this kind of maintenance.Restoring a few hundred megabytes (MB) of data to a scratch directory and running a head-cleaning tape should take no more than 15 to 30 minutes.When running a test restore job, always restore the data to an alternate server folder path, so as not to disrupt the use of any shared folders.Building a Computer System Backup and Restore Procedure ChecklistIn times of crisis, the most crucial issue becomes how quickly you can get the data back onto your system, undamaged. So, as you build your computer data backup system, be sure to document your test procedures into handy checklists.This documentation also can be great for cross-training and crucial for avoiding panic during an emergency. Be sure you have a hard copy of this documentation next to your system and stored off-site with your backup media.Watching the Log Files of Your Computer Data Backup SystemIn addition to running test restore jobs, you must inspect your computer data backup system log files daily. When the backup system is first installed, take time to get familiar with the way log files look when everything is working. This way, if something goes awry, you'll be better prepared to pinpoint the nature of the problem immediately.As network operating system (NOS) suites and backup software have become more sophisticated, it's now possible to monitor backup system log files remotely and more proactively. In most cases, the backup system log files are just plain text (.txt) files.Many third-party tools and utilities, as well as those included with Microsoft BackOffice Small Business Server (SBS) and Microsoft BackOffice Server, can automatically e-mail or fax a backup system log file at a preconfigured time.Automatically and Remotely Monitoring Tape Backup Log FilesMany computer consultants have their small business clients' log files automatically e-mailed to them daily, so the consultants proactively can watch out for potential problems with the computer data backup system.However, don't think this proactive monitoring is limited to professional consultants. If your company has one or more branch offices you support from a centralized location, you also can use a similar method to monitor backup system health in remote locations.For greater flexibility, you can set up an e-mail alias so the computer data backup system log file automatically is sent to you, your second-in-command and perhaps an external computer consultant - so you are all kept in the loop. Also, this way, monitoring continues even when you're out of the office or on vacation.The Bottom LineIf your small business depends greatly on its computer systems, backing up your data is not optional and it is not something that can be casually brushed to the back burner.Use the computer data backup tips in the articles to help you become a more IT-aware small business owner. And remember, when it comes to computer data backups, "Test Now or Cry Later". The choice is yours.Copyright MMI-MMVI, PCSupportTips.com.

Virtual Private Network in Banking

How does Virtual Private Network service work in banking?Whenever you use the internet through an Internet Service Provider (ISP) or at another site, your computer is given an address on that provider's network. While you can reach your bank from the Internet, you will normally be denied access to services that are restricted to bank network addresses because your computer is using an address from an external network.But, if you are on the internet, you can still connect to the Banks VPN service, in two ways. From a web browser or with a software VPN client. A VPN need not have explicit security features, such as authentication or content encryption. Virtual Private Network setup, can be used to separate traffic of different user communities over an underlying network with strong security features.Seek secured private connectivity across public IP networks!Extends geographical connectivityImproves productivityImproves securityReduce transit time and transportation costs for remote usersReduce operational costs versus traditional WANSimplify network topologyProvides global networking opportunitiesProvides broadband networking compatibilityProvides faster ROI than traditional WANProvides telecommuter supportVPN are categorised into two types: Remote access VPN Site to site VPNWhat is site to site Virtual Private Network in banking?Such Site to site VPN allows you to have a secured connection between locations across the open internet. With the help if site to site VPN your bank can save a great deal of money, as you can use cheaper means always on connections such as domestic broadband rather than expensive leased lines between sites.What about Remote access VPN?Remote access VPN also known as Virtual Private Dial up(VPDN) is used by banks who have staff regularly working in locations outside the office. You can connect into the office network over dial up phone/isdn lines or over broadband from anywhere.Virtual Private Network banking uses advanced encryption and tunneling to permit computers to establish secure, end-to-end, private network connections over insecure networks, such as the Internet or wireless networks. VPN services can impact your overall computing and network performance. VPNs exist to protect traffic on public data networks like the Internet. VPN Services will work with other ISP dialup services too. Try your online route for your VPN.
