As this is the information age, most firms use other forms of media to store their valuable data. However, there is one form called the tape drive that are still used by many organizations worldwide. The notion of tape data recovery still entails mystery and how it is to be done. This type of recovery is to recover any data that has been lost on a tape.
How can a tape cartridge be damaged? It can be damaged from smoke, dropping into the water, or simply just dropping from high levels. It can also be damaged from the exposure from the sun, extreme temperature, internal mechanism failure, and errors that are located found within the tape’s file span.
There are various cases of damages namely from water damage, missing oxide, folds in the tape, blade damage, bad oxide or even frictional damage, when tape data are being recovered. The fact that there are 2 types of tape data recovery, physical and logical recovery. Read on to find out more how you too can engage in the recovery techniques, if you are using tape as a storage medium.
What is needed for a physical tape recovery?
When there is a physical damage to the tape, a physical tape data recovery will then be required. It can be due to the damage done physically to the plastics, cartridge, or the tape itself from preventing the data to be read effectively.
Physical damages are needed due to the deterioration of magnetic coatings on the actual tape surface, cracked wheels, twisted tape, creased tape edges, broken tape, stretched tape, or any other damages connected with the actual tape itself.
Most places that are dealing in tape data recovery guarantee a high physical recovery rate of 98%. They claimed that they have trained professionals to execute this type of task.
If you thought you have damaged your tape storage media by accidentally dropped it in the mud, water or simply from high level, then you should immediately stopped what you are doing and head to those tape recovery offices so that those recovery professionals can help you.
What is logical recovery?
Logical tape data recovery is more complicated than physical recovery, and is also more expensive than the normal recovery techniques.
We need logical recovery when the data is unable to read or write even though it has been successfully recorded onto the tape itself. Or there are no visible form of damage to the tape and the tape body itself.
In order for the technician to execute the recovery procedures properly, he has to use multiple versions of the tape recovery software and take many “passes” at the tape using it.
You can easily pieced back the damage or lost tape data, but the rate of success of logical tape data recovery is much lower than physical tape recovery.
