Recovering Data from RAID

Modern operating systems have many features to enhance data security and usability. In this article, we will compare RAID LVM and RAID mdadm -- two interesting technologies whose main purpose is to keep your server, computer, or NAS up, and to save your data in case of hardware failure.

The "zero" format of RAID arrays today remains almost the most popular among all the options due to the minimal cost of the basic RAID 0 configuration. What are the advantages and disadvantages of the format? What are the problems RAID 0 users face most often? How to avoid problems with such disk arrays or solve them with minimal losses? What to do if the RAID is corrupted? How to recover data from RAID 0? Let's learn this together.

In this article we will look at how to recover lost data from a RAID 10 array.

The intensive development of Internet technologies has forced everyone to look at data security from a completely different angle since the consequences of losing important information can be measured in thousands and even hundreds of thousands of dollars. It led to the appearance of disk RAID arrays whose main purpose is to prevent data loss in case of hard drive failure. In this article, we will find out how to recover important data if a RAID 6 array fails.

RAID 1 is probably the most robust RAID type, but even it can fail. In this article we will look at the main causes of RAID 1 failure and how to recover from it in case of an unexpected RAID 1 malfunction.
