10 Data Recovery Tools You Can Download

In cases of disaster strikes, file get deleted or corrupted accidentally or some unfortunate happen that prevents access of files. For such there is no need to fret since once a file is deleted, the file is recoverable as the system marks the residence of the file as reusable hence removing from its index the file. This then gives a period of recovery of the file. Below is a list of tools free to download and you can use to recover files from full partition rescue to simple recovery of files.


1.) PhotoRec.

PhotoRec is very powerful recovery tool type command line that recovers data lost through bypassing system file and works perfectly in cases where your computer cannot have any access to the drive but can see it. The application works on multiple platforms and different formats of drives even drives in OS X.


2.) Recuva.

Recuva comes with multiple tools to make easier recovery of data. Recuva scans drives deeply and helps recover deleted data from drives or drives that are formatted and damaged. This application is capable of recovering data lost due to power off or unsaved work from applications such as email or Microsoft Word temp folder. The application comes with a wizard to guide on its working and implementation.


3.) TestDisk

TestDisk is accompanied by PhotoRec package that will be used to repair broken system file then make drive usable requiring no formatting and the data in it too. The application cuts on time spend on recovering large amounts of data. The application rebuilds Windows formats and is available for use on different operating systems.

4.) Ultimate Boot CD.

7.) Restoration.

Restoration comes as EXE file that requires no installation for it to run and is small in size, 400KB. It is a must have app as it runs easily on Windows machine.


Disaster recovery techniques for database systems

Recovery techniques are an important factor in the database management systems. The database recovery system is a highly complex system composed of many transactions that are being executed each second. The system may undergo different types of failure including;


  1. Transaction failure

When a transaction fails to execute, it has to abort. The failure maybe as a result of:

  • Logical errors

This refers to any internal error such as code errors that make a transaction to be incomplete.


This is where the database management system aborts an active transaction due to a system failure condition such as deadlock.


  1. Disk failure

Disk failure attributed to, when the hard-disk drive fails due to disk head crash and bad sectors among others. This annihilates the disk partially or fully.


  1. System crash

External errors such as power supply shortage may lead to a sudden stop in the system activities which may cause the system to crash thus leading to loss of certain data that had already been executed.


When the system undergoes such failures, it has to undergo some sort of techniques to recover the lost data. Such techniques may include:


  1. Incremental backup

This is an efficient and reliable way of backing up your data. Files that have been changed are copied to archive after a transaction is completed or at intervals. In incremental backup, not all files are backed up, it’s only the once that have been modified overtime.


Incremental backup is fast and reduces the storage space since the only backed up data it consists is the modified files. During recovery of data, it provides grounds whereby data can be recovered to a more precise point in time. However, it takes long to restore data

  1. Audit trail

This refers to a series of activities on log files that are recorded. This technique provides security since it records all activities from all users. If data is lost, the audit trail, gives track of track accessed files, whether complete or attempted. It is essential in recovering data since it traces the transactions that have altered the log records.


  1. Differential files

Differential files refers to the differential backup type in which data is preserved and only the difference in data is saved since the last full back up. Differential back is quicker in terms of data recovery time since it only requires a full back up and the last differential backup to restore the lost data.


  1. Salvation program

This technique is applied when all other methods of data recovery fail. It is often put into effect after a system crash so as to restore the system to a valid state and is normally applicable where in buffers were lost in a system crash. Salvation Data has data recovery tools that prevent data loss and also necessitate high success rate in data recovery.


  1. Multiple copies

During the database transaction operations, multiple copies of each active files are maintained. The essence of this is to ensure that, in case of failure, different versions of files are available and can be recovered easily by making comparisons between the versions that can help in finding a consistent state version of the file. In this case, a valid state version of a file can be restored easily.

These techniques are very essential in data restoration in case of a disaster. However, not all data may be recovered but at least some of it is guaranteed.


Know about the importance of the data recovery process

Computer Repair

In the computing activity, the data recovery is one among the process of recovering the lost, damaged, corrupted, formatted, or inaccessible data from the auxiliary storage, files, or removable media. In normal terms, the erased data cannot be accessed in a usual way and the data is commonly recovered from the storage media that includes external or internal drives. Basically, all the data written on your computer are written onto your computer hard drive and if you delete any data from your system, then the data on the hard drive will not be deleted. Instead, the hard drive will mark the occupied space as vacant and still the data will be present in the drive. So even you can recover the data when you have mistakenly deleted the data on your system.

Data Recovery

All the computer users should be aware of the problems in data recovery. The data recovery is defined as the process of recovering all the lost data caused due to a blackout, shutdown interruption or due to some other issues. This can be extremely confusing and frustrating time, mainly if one who works through online or sometimes the valuable data may lose. This can be rectified by learning some recovery tips and by that you can understand about how to react to the data recovery and to get back the lost information. You are supposed to use the file recovery to save lost, corrupted and other files.

Data Recovery

The initial step is to get prepared. First of all you need to find the name of the files you think you lost which makes you easier on going through with the recovery data. Normally in windows the systems are built well and some important features such as support for coded offline folder, improved recovery policy, color support and also some additional security characteristics to protect EFS data. This helps to protect and set the windows network when you are not offering all these features with some other operating systems.

In windows surroundings, there are some several software and other applications you can use to data recovery. These make the process as fast and easy for you. For the person who is more experienced computer user this is the good method and those who are not know about the system this acts as very good process.

Always make sure you are using the correct protection measures while going through the recovery process. Protecting data generally ensures that if sometimes anything went wrong during the process of backup, you will have that information there itself and you need not to worry about that. Protecting helps you to put all your worries easily since you know even if this is your first time of recovering data you need not to worry about losing of the important data. These instructions are more important and yet the basic information related to the data recovery in which all the system users should be aware of.
