PC Backup Software And Data Deduplication (Part I)
The one thing that has definitely revolutionized how PC backup software works is Data deduplication. Gartner calls it “inarguably one of the most new important technologies in storage for the past decade.” So let’s take a detailed look at what it actually means.
Data deduplication or Single Instancing essentially refers to the elimination of redundant data. In the deduplication process, duplicate data is deleted, leaving only one copy (single instance) of the data to be stored. However, indexing of all data is still retained should that data ever be required.
For example, a typical email system might contain 100 instances of the same 1 MB file attachment. If the email platform is backed up or archived, all 100 instances are saved, requiring 100 MB storage space. With data deduplication, only one instance of the attachment is actually stored; each subsequent instance is just referenced back to the one saved copy reducing storage and bandwidth demand to only 1 MB.
The practical benefits of this technology depend upon various factors like:
- Point of Application: Source Vs Target
- Time of Application: Inline vs Post-Process
- Granularity: File vs Sub-File level
- Algorithm: Fixed size blocks Vs Variable length data segments
This article is the first in a series that will attempt to explain how each of these factors defines the success of a PC backup.

2010 Top Rated Data Recovery Hardware
Who Should use Data Compass?
Data Recovery Companies, IT companies, enterprises’ data security dept., computer training and repair centers, universities, military and government agencies, etc.
Why you should use Data Compass for data recovery and data security?
Data Compass supports all brands of drives without capacity limit for both data image and data recovery, without back door design, requiring no internet.
Data Compass is one data recovery hardware used to extract data from patient drives with high success rate. Connect the patient drives to Data Compass, you can visually find the lost data and select which data you want to recover and save in the donor drives. For drives with severe bad sectors or unstable heads or motor, you can use Data Compass to image the patient drives with Shadow disk and then recover the data from Shadowdisk so as to protect the source drive from a second damage. You can also disable the patient heads or select the working heads and recover data from the good heads.
Data Compass also recover data from undetected drives
So far it works with Hitachi undetected drives without bios detection due to firmware failure and also Data Compass works with Western Digital undetected drives due to one head damage, you don’t need to find a donor head for head replacement but load the firmware from another head and recover data directly.
The most important is that users don’t need to spend a lot of time to learn this tool, you get it and you use it well! Easy but super powerful!

Top Reasons Why Data Loss Occurs
Dealing with the aftermath of an earthquake or hurricane, especially in terms of the physical loss of personal and business property, is bad enough, but what you may not always realize is that such an event can also have a catastrophic effect on your digital assets as well.
It’s always difficult to rebuild, but it may not even be possible if you lose critical data like customer information and accouting data. After a natural disaster occurs there little chance of finding anything left of your computers to attempt to recover the lost data.
Data loss is most often caused by viruses and other malware programs. A single virus can replicate and impact many computer files.
Other viruses can be even more dangerous and can delete files, damage the operating system or even prevent access to the entire disk drives. Things get even worse if your computer gets a virus that takes your identity and puts your financial accounts at risk.
Every year, companies lose significant amounts of money and time as the result of data loss which, more often than not, is due to simple human error. Studies show that as much as 75% of data loss can be attributed to human factors. The main causes of loss seem to arise out of the use of laptops, email, mobile devices and databases.
Stopping Laptop Data Loss Before It Happens
Notebook Data Recovery- A Specialist in Its Own Unique Way
Notebook data recovery includes in-cooperation of a technique to generate the lost data. The experts load software that generates a copy of the data which can be saved on the CD or the pen drive. One can also retrieve files that got deleted accidentally. Hence, it is a convenient solution for the users who get disheartened due to loss of a database file due to memory crash.
The data loss or crash can be a problematic issue, as everyday work would be delayed, despite the notebook data recovery technique. Not only this, the consequences can be a hazardous for whoever concerned. This creates the need to prepare a backup file, which stores all the user data and one can process them in need. This technique saves the amount required to retrieve user data from the notebook data recovery technique.
If the hard drive crashes, then you can send it a hardware expert. Moreover your day to day activities won’t be interrupted due to data loss. You can carry forward the work on another laptop or computer. In the mean while the notebook can be send for repair.
So, one can bring these features into consideration and enjoy smoother notebook functioning. Buying a notebook can be very fruitful as it is very easy to carry equipment that simplifies the everyday process. But everybody should be confirmed about the warranty of the hard drive. They are prone to crashes and you’ll need notebook data recovery tool at your disposal. The internal parts of the hard drive consist of mechanical disks. The data is stored on the mechanically coated platters that save data along the tracks and sectors.
Notebook Data Recovery Tackles All Hard Drive Crash Issues
The data loss occurs due to physical, non-physical, fire or water related issues. These issues are dealt via notebook data recovery techniques. These are technical aspects that retrieve the stored user data and repair the damages in the hard drive. The task is done with help of data recovery software and tools. Till then you need to follow some tips to avoid further damages.
If your notebook hard drive suffered from physical damage, then you should follow some instructions to avoid major damages. Beware of the strange noises or grinding in the drive. The ideal way is to turn off the computer immediately and abort the usage till it gets repaired. Its continuous use can be dangerous. Never disassemble or clean a hard drive, if it gets damaged. You should take it to the notebook data recovery expert to get access of the data and repair the drive.
At times, the data might get lost due to non-physical damage of the hard drive. In case of non-physical drive failure, some of the files or folders would go missing. You can also get syntax messages like “No OS found” or “Corrupt volume” etc. Hence, you shouldn’t run CHKDSK or V repair command on the non-physically corrupt computer. Switch it off immediately and send it to a hardware expert.
