Online Data Recovery

"Online" or "Remote" data recovery is yet another method to restore the lost or deleted data. It is same as performing the regular software based recoveries except that this kind of recovery is performed over the Internet without physically having the drive or computer in possession. The recovery technician sitting somewhere else gains access to user's computer and complete the recovery job online. In this scenario, the user doesn't have to travel or send the media to anywhere physically.
Although online data recovery is convenient and useful in many cases, it still carries some points making it less popular than the classic data recovery methods. First of all, it requires a stable broadband Internet connection for it to be performed correctly, which many third world countries still lack. Also, it cannot be performed in case of physical damage to media and for such cases, the traditional in-lab recovery has to take place.
