recovery

RAID 1 data recovery is necessary if a RAID 1 is used. The minimum configuration for this would be 2 hard disk, and will be in increments of 2, since this particular configuration must have an even number of hard drives.

This particular device refers to the fact that the disks were essentially a mirror on each other together. So, once data is written to a disk, the same information is mirrored or copied to another disk at the same time. The main advantage of thisspecial configuration is that it is a complete data redundancy, which better protects your data in case of failure of a disk provides.

There are two types of installations, especially for RAID 1, I briefly below:

Software RAID 1 refers to the fact that the hard drive to a large extent by a combination of a controller (standard) DSC is a software utility to manage the various units of a RAID volume. Remember, he iswill become a RAID 1 must have an even number of units. Many experts said they prefer to set up the software because they want to establish more reliable and less vulnerable to hardware, which is not typical to feel subject to wear and tare.

Hardware RAID-1 when the volume is not a physical controller to mirror the data for all units of volume dependent. The biggest problem that has been said or complaint with this device is that, because the hardwareit is subject to failure in a much larger scale if the software is used. However, you receive a large number of professionals who swear by this series and refuse to use the alternative.

The biggest advantage of using a RAID 1 configuration, all data is written twice, and essentially mirror, so if there is a fault on a record that in many cases the data is secure and protected disc ago, mirroring. This makes data recovery RAID 1much easier to perform. Obviously with the good comes something bad is it? There must be a mirror drive for each unit in the configuration, you lose a significant amount of physical memory. Moreover, the nature of the units are set to mirror, because if the bad or corrupt data written on a disk, it is automatically reflected in the other disc, which is when the need for data recovery RAID 1 increases exponentially.
