Important Distinctions Between Full System Backup, Continuous Backup, and Incremental Backup

There are many methods of data backup, stemming from many decades ago to the very recent past. Here we'll address a few different kinds of backup and some of the more technical aspects of their usefulness.

Unstructured Backup - This is when a user performs data backup of selected material manually, usually to Jazz or CD, with minimal regularity, continuity, or organization. It requires a low amount of investment and little effort, but yields a low level of recoverability.

Full System Backup - This is when a user executes a backup of the entire system disk, creating a duplicate image. Full system backup can be performed manually or on an automated schedule. It enables a high level of recoverability, but takes a long time to perform, so it is usually done biweekly or monthly. It often requires professional guidance during the restoration process as well.

Incremental Backup - This is the most common data backup method on a professional level. Upon initiation, a full system backup is performed to create a baseline. Thereafter, incremental backups are performed which only backup changed data. There are various methods of accomplishing this. Simple incremental backup just backs up whatever data has changed since the last time an incremental backup was performed. It they are scheduled to run daily, an incremental backup will record all changes made for the last 24 hours. This is considerably faster and less resource-intensive than a full system backup. The downside is that it further complicates the data restoration process, as it will be incomplete without each piece of incremental backup data (there can be hundreds or thousands).

Another form of incremental backup is differential backup. Like incremental backup, it begins with a full system backup, then tracks changes made. Unlike incremental backup, a differential backup system records the changes made relative to the initial full system backup. This means there is more data getting backed up, so the process takes longer than simple incremental backup. Yet it only requires two files to fully restore a system - the initial full system backup, and the most recent differential backup. This is often considered the best simple compromise between full system backup and simple incremental backup.

Yet a third and more sophisticated variety of incremental data protection is the multi-leveled or multi-tiered incremental backup solution. In this solution, backups are scheduled and designated levels or tiers. Level 0 is a full system backup. For each other level n, backup data is tracked relative to the most recent n-1 level backup. If you start with a level 0 backup, then schedule level 1 backups Mondays and Fridays, and level 2 backups Wednesdays, The Monday and Friday backups will record everything changed since the initial level 0 backup. The Wednesday backups, however, will only record changes made since Monday, because it is a level 2 backup (and Monday's was a level 1). Though more complex, this system allows for a much higher level of resource management. For large amounts of data (thinks terabytes of corporate data) this can be a significant boost in available processing power. By customizing your incremental levels, you can optimize your ratio of data security to processing power consumption.

The most recent advent to mainstream data security is continuous backup. It is essentially a modernized, upgraded version of disk mirroring. In a disk mirror scenario, a backup drive is setup to simply mimic a drive you select - every change continuously throughout the day. Continuous backup takes this concept one step further by tracking the changes made, enabling the user to roll them back and thus restore their system to virtually any point in time. This is the simplest and most reliable backup method for home users and small business - situations in which there is a limited amount of data changing at any given time. The only limitation is processing power - a newer system is important to manage to disk syncing without perceivable changes in performance. Continuous backup can also be successful for large-scale operations, provided it is implemented at a low (user-end) level (such that there are a manageable number of changes processed at any one given time). For home and small business users with older systems, differential backup can offer better performance, but provides a lesser degree of reliable system restoration and requires more user input and understanding of the implemented software. Ultimately continuous data protection is an excellent upgrade solution for home and small business users in the process of upgrading their older computer systems.

At Rebit, http://rebit.com, Dennis and two co-founders created something referred to as "ridiculously simple backup". Rebit products are ideal for small business, relieving the burden of backup for IT providers and PC users.

Top 10 Signals That Your Hard Drive Is About to Crash

Nothing lasts forever, including your computer's hard drive. Hard drives are mechanical devices and as such they will eventually wear out and stop working. When this happens you may lose any data stored on the drive, and if you don't have proper backups in place, there is no guarantee you can get that data back.

Fortunately, in many cases, your hard drive will begin to show signs of degradation before it fails completely. There are no guarantees, but this may give you time to properly back up your files and replace your hard drive before it dies completely.

Here are the top 10 signs of an impending hard drive failure:

1. Unusual grinding or clicking noises.

If you hear any unusual sounds coming from your computer, it may be a sign of mechanical damage within the hard disk. Often it's an indicator of damage to the read/write heads. If the read/write heads are damaged, they can come into contact with the disk platter, marring the surface and making it impossible to access your data.

2. Your computer locks up during booting.

Virtually all computers experience this problem on occasion, but if it happens regularly or becomes increasingly frequent, it is often a sign that there is a serious problem.

3. Files suddenly go missing for no apparent reason.

If files start to disappear and you're sure you haven't deleted them by mistake, it is likely a sign of hard drive failure. Sometimes the deleted files may not be important, but you may begin to lose important system files that could drastically affect the performance of your computer.

4. Incredibly long wait times to access your files.

Sometimes it takes a little bit longer to access your files than usual. This is normal and can be due to a variety of factors. However, if it routinely takes an extremely long time to access your files, this can be a sign that your hard drive has been compromised.

5. You get a message that your hard drive is not recognized by the system BIOS.

If you get an error message saying that your system BIOS (Basic Input Output System) can't access or doesn't recognize your hard drive, you have a problem. Another variation of this scenario is that the drive is identified as being a different make or model that it actually is. Either way, in all likelihood this means your drive is not working properly and needs to be replaced.

6. Your computer frequently locks up during the booting process.

Sometimes computers lock up during the booting process. In isolation, this is not necessarily an indication of a bigger problem. If it begins to happen on a regular basis, chances are that the drive is beginning to fail.

7. You get an error message saying that the hard drive is not formatted.

This is a sign that your hard drive is very close to complete failure. Occasionally you may be able to reboot your computer a couple of more times and get it to work, but this is a certain indication that you need to back up whatever files you can and replace the drive.

If you do get this error message, don't be fooled into trying to reformat the drive as this will cause you to lose all of your data.

8. You get an 'operating system not found' error.

This is an indication that your hard drive is severely damaged and is not working at all. If this happens, your computer can not detect the drive and you'll need a new hard drive as well as the services of a data recovery company to retrieve your lost files.

9. Your computer frequently reboots on its own.

If this happens occasionally, it may not indicate a bigger problem, but if your computer often reboots on its own during use this can be a sign that your drive is approaching the point of failure. If this problem starts to happen with increasing frequency, it's a very clear sign that there is a major problem.

10. The "Blue Screen of Death."

The dreaded "Blue Screen of Death" is more technically called a Stop Error Screen, and presents itself as a series of error messages on a bright blue background screen. A stop error screen can be a sign of any one of several computer malfunctions and most commonly indicates a problem with a device driver. However, it can also be a sign that your hard drive is near the end of the line.

If you see any of these signs, the best thing to do is to back up your files as soon as possible, with the most important files taking priority. Recognizing these signs and acting on them quickly gives you a better chance of saving your important files.

If your computer has already crashed, you may want to contact a reputable data recovery company. A data recovery specialist can recover lost files in many cases. The sooner you take action, the better chance that you can save your data.

QuickBooks Recovery in Case of "Unexpected Error C=422"

Intuit QuickBooks is a reliable accounting software specifically developed to manage businesses of small and medium enterprises. It keeps track of all the information pertaining to the company, its employees, customers, and vendors. It maintains record of the company's sales, chart of accounts, taxes, credit card activities, invoices etc. all at one place. A QuickBooks data (or QBW) file often gets corrupt due to its custom database format.

As a result, sometimes it becomes very difficult to identify the real cause of corruption. Operating the file in a multi-user networking environment is another major reason for QuickBooks corruption. Corruption leads to QBW file inaccessibility and data loss. To overcome the problem, you need to repair QBW file through a reliable third-party utility.

For instance, you try upgrading your QuickBooks 2007 to QuickBooks 2008 version. When you attempt to open a company file after the upgrade process completes, you may come across the following error message:

"Unexpected Error, C=422"

You may receive another message like as follows:

"An error occurred when QuickBooks tried to open the company file. Please try again. If the problem persists, contact Technical support (-1,0) or (-14114, 0)."

Cause:
These errors occurred because the QuickBooks application has encountered some corrupt data in the company file. This corrupt data might be present in the file before the update.

Resolution:
To repair corrupt QuickBooks file, follow these steps-

Start the older QuickBooks version.
Try restoring the backup that you made during the update process.
When the file is successfully restored, go to 'File' menu, click 'Utilities', and choose 'Verify Data'.
You will see one of the following messages:
"QuickBooks detected no problems with your data."
If this message is displayed, then try updating the company file in the new QuickBooks version.
"Data has lost integrity."
If this message is shown, then rebuild the company file. To make sure all the damage has been repaired, run the 'Verify Data' command again after completing the rebuild process.

If the problem still persists, you should take help of an efficient QuickBooks repair tool. They are extremely safe and easy to implement. They display preview of all the recoverable components in the application interface. The built-in 'Automatic Update' wizard helps the users to keep the software up-to-date.

Stellar Phoenix Recovery for QuickBooks is an excellent utility that repairs QBW files created in QuickBooks 2007, 2008, 2009, and 2010 (US Version). It is compatible with Windows 7, Vista, Server 2003, XP, and 2000.

Top 10 Tips to Prevent Data Loss

For many people, the information they have stored on their computer is invaluable. Whether its family photos and memories, important business data or sensitive financial information, the effects of the loss of this data could range from disappointing and frustrating to completely debilitating.

In many cases, you can recover lost data with the help of a reputable data recovery company, but the fact remains that there are sometimes no guarantees with this process and the best defence is to take reasonable steps to prevent the loss of your data in the first place.

Here are the top 10 things you can do to reduce the chances of losing important files and information:

1. Back up important files on a regular basis.

This seems self explanatory, but many people don't do it. Why wait for disaster to strike before taking steps to protect your most important data? You can store your backed up files on disk, on a USB flash drive, an external hard drive, or use a web related service to back up your files. While it's not practical for all applications, you may want to consider keeping hard copies of your most important data files. A physical hard copy is usually much safer and then, worst that can happen is that you have to re-enter the information manually from the paper copy.

2. Don't store your data and your operating system on the same hard drive.

Many word processing programs automatically store your files in the "My Documents" folder on your hard drive. The problem with this is that anything that compromises your computer operating system may delete or corrupt your data files as well. A safer option is to partition your drive into a program file zone and a data file zone. Then, if you have problems, (short of a total disk failure), you still have a good possibility of retrieving your files from the data partition.

3. Use a good anti-virus program and keep it up to date.

Viruses and malware are among the most common threats to your computer's well-being. Most viruses spread through the internet and email communication, so you need to have a firewall and up-to-date anti-virus software. New viruses appear frequently and older, out of date anti-virus programs may not protect against the latest threats. This doesn't mean you have to purchase new software, but rather that you need to install the latest updates for your current anti-virus program regularly.

4. Use power surge protection.

Using an un-interrupt power supply (UPS) protects your computer against power surges and power failure. The battery in the UPS allows you time to shut down your computer properly and avoid damaging your files or hardware components.

5. Keep your computer well protected.

Your computer should be kept in a cool, dry area, away from direct sunlight. The computer's internal components can be damaged by moisture and heat. If possible, it should also be placed in a low-traffic area of your home where it is less likely to be bumped or knocked off its table or stand.

6. Don't move your computer or laptop while it's in operation.

Your computer is especially vulnerable to physical damage while it's in use, so you should shut down your laptop or notebook when you are in the process of carrying it from one location to another.

7. Don't use file or disk encryption unless absolutely necessary.

If you keep important business data on your computer, there may be some justification for using file encryption, but otherwise, encryption is unnecessary and makes it more difficult to recover your files if they are lost.

8. Turn off your computer when it's not in use.

Your data is safer when your computer is turned off, so if you don't plan on using the computer for a significant period of time, you're better off to properly shut it down and turn it off.

9. Stop using your computer if you begin to see signs of data loss.

If you notice some of your files have mysteriously gone missing, or you hear grinding or clicking noises from your hard drive, back up your most important files (if you can) and then shut down your computer. Continuing to use your hard drive may result in some of your key files being over-written and lost forever.

10. Be careful when running diagnostic programs.

Some diagnostic programs, such as Check Disk and others can cause problems in retrieving lost data.

It's OK to use them to check on the health of your computer and make sure everything is running smoothly, but if you allow it to repair data files, it can make the data recovery process much more difficult.

When it comes to protecting your computer against data loss, the key is to develop good computer habits and take simple steps to keep your computer running well and keep your data as safe as it can be. While you can't prevent all causes of data loss, you can take steps to reduce the risk and minimize the damage that a data loss event can cause.

Microfiche to PDF Conversion

Microfiche as a format is still a very good storage tool for keeping documents in a small and handy place. Obviously this isn't up to today's standards, but in their time they were revolutionary. But these days, companies are taking out their old microfiche collections and looking at converting them to digital and usually the widely-used PDF format.

This is mainly because microfiche readers have become more expensive and harder to get hold of and, more importantly, it is basically a format that has run it's life span and we have moved onto a updated data type. It's not really possible to convert microfiche using a standard scanner so businesses and individuals have been outsourcing them to document scanning and microfiche conversion bureaus.

This makes sense since companies in this sector have invested hundreds of thousands of pounds in order to purchase the latest equipment to be able to process microfiche and microfilms (or microform as they're collectively known) quickly and effectively. This is turn saves time which saves costs overall when completing microfiche to PDF conversion. With top quality scanners, hundreds of microfiche can be scanned and converted each day whilst being watched carefully by a specialist in that field to ensure that everything is alright with the files, the microfiche themselves and the alignment and contrast of the output images. Clean up services are also usually available from these bureaus if required.

Microfiche can be converted into other formats such as TIFF, but PDF is by far the most common, primarily due to it's quality, size and usability; the very foundation of the microfiche in the first place.

When using a company to complete microfiche to PDF conversion, make sure to check out some of their previous work by requesting samples, preferably of your own fiche and also go and see the bureau in action if you are located closely if you are still unsure. If they are a serious company, they will happily allow you to come along and see the process.

Microfiche to PDF conversion is simply the logical way forward as is converting all documents into digital formats. It has become more than a mere luxury and is now essential for a lot of companies for the sake of their efficiency, time and costs.

Steve is marketing manager with Pearl Scan, a document scanning and microfiche conversion company based in the UK. We offer microfiche to PDF conversion using top quality microfiche scanners which can process hundreds of fiche per day with crisp picture quality and quick indexing services.

Easiest Way to Deal With MDB File Corruption

Nothing can be worse than dealing with the corrupt MDB file. Corruption of MDB file means inaccessibility and loss of crucial data, forms, reports, procedures, triggers, views, etc. Therefore, taking preventive steps while working with MS Access is always suggested. For example, MDB file that contains text, forms, and reports all is more susceptible to damage than the MDB files having only text, forms, and reports. That is why it is always suggested to maintain different Access database files to store text, forms, and reports.

The second case where prevention can be a big relief is related to the database file shared over network. When MS Access database is being used in shared mode over network, then you must take care about following points:
-The file shall be closed properly.
-MS Access shall be closed in a proper manner after the use of file is finished.
-Network connection shall not be lost while using the database.
-There shall be no power sabotage i.e. the computer having database file shall not be closed abruptly.

Considering the above listed facts often keep MDB file miles away from damage making you happy all times. However, you follow the preventive steps listed above, nobody can predict about the corruption of Access database. The reason can be hardware failure, software failure, virus attack, or any other similar one.

Here we tell you about repairing the corrupt MDB file for getting the lost data back with complete precision. Before trying any other tool, you can give a chance to Compact and Repair tool, which is a default Access database repair tool available in MS Access. The tool produces best output particularly when corruption is less. But, if database has major damage then the tool will not be a help for you. However, before using Compact and Repair tool, you shall backup the damaged MDB file because it may happen that during the repairing process, the file will become more corrupt. So, if you will be having the backup copy then you can use any other third party tool for getting the lost data back.

There are so many access files repairing tools available in the market that guarantee to deliver 100% satisfactory output. But, not all of them stand at their promises. However, there are tools that are known for completing what they promise to do. One of such tools is Kernel for Access Repair.

Kernel for Access Repair is an outstanding, excellent, and cost-effective MDB file repair tool. The tool is available for free download as an evaluation version, which allows verifying its capabilities and recovery percentage. Remember that only the tool that provides quality output is available for free download so that you can first make up your mind with the output given by the trial version. The software supports MS Access 2010, 2007, 2003, 2002, 2000, and earlier versions for repairing MDB data. The software not only recovers the lost data but also maintains their original formatting and structuring.
