What All you need to know about RAID1 Recovery is Right Here!
Data loss and drive failure is common today. Virus attacks, corrupt data, hardware conflicts, overwritten files and server crash are some of the commonly observed failures that lead to loss of important data.
There are many advanced tools that are used for data recovery nowadays and one of them is RAID recovery. RAID or Redundant Array of Inexpensive Disks is a recovery tool that disseminates data across multiple disks to increase storage capacity. RAID0, RAID1, RAID5 and RAID6 are the various raid recovery tools.
RAID1 distributes data across several disks. It provides complete data redundancy in the event of a drive failure. A minimum of at least 2 hard drives are required to create RAID1 volume. In RAID1 disk, information is written to the first drive and then to the second drive, simultaneously. This will not lead to the loss of data even if one of the hard drives fails. Although RAID1 protects against data loss but that does not mean that it completely eliminates the risk of information failure because damage can be mirrored and some of the information might become inaccessible. Therefore it is essential to have a back up.
RAID1 recovery is possible but it requires the help of professionals. The safest way of RAID1 recovery is to create a block level copy of each sector on the hard drive. There are pros and cons of using RAID1. Although RAID1 has high performance and it provides high data protection but the redundancy cost is also huge and it consumes twice the storage space because data is duplicated.
To maximize the performance of RAID1, it is better to use independent disks and adding drives to the mirror. Data reliability in RAID1 array is higher than RAID2, 3, 4 or 5 but lower than RAID6. RAID1 can be used together with RAID0 (RAID0+1) that provide the benefits of striping and mirroring.
RAID1 recovery is a tricky and complicated process. It would be an amateur decision on your part if you plan to carry raid1 data recovery on your own. The help of professionals is very essential. They will identify the nature of problem and will follow certain prescribed steps and procedures for retrieval of information. In the situation of raid1 failure, it is important to follow certain steps so that the chances of information loss do not increase. Do not try to restart your system and do not read corrupt files. Always ask for expert help. There are many data recovery companies that provide online recovery services. They also assist you by providing a trial demo on their website. A certified company will always give the option of money back in case they fail to successfully recover the lost information. If you are concerned regarding the amount to be incurred on their services and are thinking to carry this task on your own, then do not commit this mistake because the losses will be much greater than the charges paid for their work. The most important precautionary step that should be taken to prevent such damages is by creating a backup of all relevant information. It is the best option and can save you from great difficulties.
