Data Recovery / Datenrettung and preservation of data in computers
Data recovery or Datenrettung is the process by which recovers information storage media damaged or inaccessible. Data recovery is done from the storage media like CD's, DVD's, diskettes, hard disks, magnetic tapes, etc. There are two reasons why data becomes inaccessible. It is logical damage and physical damage to storage media.
Physical damage to storage media can occur in many ways. Magnetic tapes can break, get wrinkled or dirt can settle on the tapes. CD's and DVD's may have scratches or the metal layer can be damaged. magnetic heads in hard drives can crash or engines may fail. The disk is notorious for not have frequently due to bending, overheating, cold, dust, etc.
There are other reasons such as fire, power surges, etc. that can cause data inaccessible or lost. There are many methods by which data can be recovered from magnetic media or optical media. The most commonly used methods are Magnetic Force Microscopy (MFM), Scanning Probe Microscopy (SPM), Magnetic force scanning tunneling microscopy (STM), etc.
In these methods place a strong magnetic tip close to the surface to be tested. It interacts with the stray magnetic field. An image of the data builds and repairs are carried out in logical damage and what data is retrieved. Many companies perform data recovery.
logical damage the damage to system files. It is not physical but a software problem and also tells us that we must be careful and have a quality system for data retrieval, datenrettung. Usually occurs due to power outages, system of accident prevention, etc. of the file system structures to be written into the system resulting file that is in an inconsistent state.
Logical damage is more common than physical damage. This can cause strange behavior like infinitely recurring file directories, data loss, system errors, reporting hard drives, negative space etc. The end result is that the operating system can not mount the file system.
Most operating systems come with repair facilities, such as, Linux has a utility fcsk, Mac has a disk utility and Windows has chkdisk installation. There are other specialized programs available that have better repair facilities operating systems.
There are also other systems called journaling file systems like NTFS, EFS (used in Windows XP), ext3 and XFS can be reverted back to its consistent state before. These file systems reduce the amount of data loss.
A data backup is the best way to prevent data loss and is the most common system for data recovery datenrettung. The simplest method is to store the data in the units in which the operating system does not load. The other method is to write data on magnetic tapes, CD's or DVDs or have an online backup.
Backups are very important for databases. backup data is of three types. Full Backup means the support of all data. Incremental backup means backing up only files that have changed. Differential backup is a mixture of these two. There is another method called continuous data protection that when data is written to disk, also written on another computer on a network.
Most individuals with a computer does not do anything in advance, just use their computers. Too late, when an incident has happened learn about data recovery or datenrettung.
