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.

Target Vs Source-based Deduplication

Target-based deduplication acts on the target data storage media. In this case the client is unmodified and not aware of any deduplication. The deduplication engine can embedded in the hardware array, which can be used as NAS/SAN device with deduplication capabilities. Alternatively it can also be offered as an independent software or hardware appliance which acts as intermediary between backup server and storage arrays. In both cases it improves only the storage utilization.

On the contrary Source-based deduplication acts on the data at the source before it’s moved. A deduplication aware backup agent is installed on the client that backs up only unique data. The result is improved bandwidth and storage utilization. But, this imposes additional computational load on the backup client.

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!

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

A more common but less attractive alternative to data recovery is data re-entry. Data re-entry is the process that an individual or business would take to duplicate the missing data. This often involves manually reentering the lost data. This process tends to be the most expensive recovery method and produces the worse results due to human errors that occur.

The data are accessed via heads that are minutely placed on the top and bottom of the platters. Usually, there is no gap for the entrance of dust particles. But the disk gets crashed if a single dust particle enters the platter surface. The hard drive can also crash due to heat impact, which leads to data loss and problems while booting the computer.
