Are you ready? Let's read!
What is redundancy?
Redundancy means having many components that offer the same functionality.
Then the disks in the array can continue to operate normally, even if part of the system fails. At the same time, fault tolerance occurs when the array continues to function despite one or more damaged disks. Thus, any threats of data loss (virus, natural disasters) become less important, since RAID can retain data despite a partial failure.
Redundancy and Backup
RAID offers redundancy, that is, some protection against single/multiple disk failure.
However, this is not a backup in any way, since it is always possible that all disks can fail at the same time or something else scary will happen. Then it will be very disappointing if important data was not duplicated in another device, and the entire array is damaged. Therefore, always be on the alert and have backups of certain important data.
Redundancy in RAID 0 and 1
RAID 0 and 1 are two complete opposites in terms of redundancy.
There is no redundancy in RAID 0; all stored information is evenly distributed across the two disks. As soon as one of the drives fails, you will lose all the accumulated information. But the performance of this array is the best.
In RAID 1, data is mirrored from the first disk to the second. If one drive fails, you can simply take data from the second drive. Therefore, the redundancy of this array is impressive.
RAID Recovery for RAID safety
With DiskInternals RAID Recovery, you have the success rate of RAID data recovery over 90%.
In addition, DiskInternals' 15 years of experience in this area can speak of the competence of this application. The program recovers files of any type from damaged RAID 0 + 1, RAID 0, RAID 1, 1 + 0, 1E, RAID 4, RAID 5, 50, 5EE, 5R, RAID 6, RAID 60, and JBOD. Absolutely, all recovered files and folders are exported to local or remote locations (including FTP). The app recovers files from a RAID attached to a dedicated RAID controller, such as Dell, Adaptec, HP, MegaRAID, Silicon, and DDF. The data recovery process bypasses windows limitations.
Use the algorithm for this application to be more confident in your abilities:
First, download the utility to your laptop, computer, or server. Then install the software. Open the RAID Recovery™ application and then be sure to select the array to scan.
Next, specify the mode in which you will work:
- Fast recovery mode
- Full recovery mode
- Reader mode
RAID Recovery™ automatically examines the current state of the RAID array, controller, and disks, and it recovers files where possible.
For you to use the preview function, all scan results will be available in 'read mode.'
The last step: buy a license for RAID Recovery™, and you will be able to export the selected files to any suitable storage device.
