Product Details
Server data recovery refers to the data rescue measures we take when a data disaster occurs in the server disk array cabinet soft array.
There is a direct connection between data storage method and data recovery.
To perform server data recovery, we must first have an understanding of disk arrays.
To put it simply, a disk array is a combination of multiple small and cheap disk drives into an array to achieve performance or redundancy that cannot be achieved with large and expensive drives. This drive array appears to the computer as a single logical storage unit or drive.
A disk array is a method of spreading information across multiple disks. It uses techniques such as disk striping (r level), disk mirroring (r level), and disk striping with parity (r level) to achieve redundancy, reduce latency and/or increase disk reads and writes The bandwidth increases the ability to recover from hard drive crashes
so data can be lost when:
. A disk array error occurs.
The specific reasons include damage to the array card, exhaustion of the array card battery, damage to the slot control chip, etc. The data recovery rate in this type of situation is quite high but there are also cases of failure. For example, it is quite dangerous if the onboard control program fails and large-scale chaotic data reading and writing (misoperations, etc.) occur.
It is recommended that when encountering an array error and data loss, try not to perform any operation without the guidance of professionals or call the customer service hotline of NetShiXiyou for quick consultation.
Note: When the array card is damaged, replacing the new array card at will can easily cause the disk D number to be disordered.
. System failure
When a system failure or even system crash occurs, some disk arrays created with the system's own functions (d, etc.) or disk arrays constructed with third-party software (etc.) will lose data. .
At this time, array logs and related records are very important. If you have detailed system logs or even backup of array combination information, maybe NetStop can solve the problem for you through free telephone consultation. Of course, if you don’t have relevant information, please don’t worry. Netshiwuyou’s technology has quite a lot of experience in this area!
. Disk failure
Although some disk arrays can tolerate a hard drive failure without data loss. However, due to poor management and the relatively stable nature of the server, which paralyzes managers, accidents that exceed the allowed number of bad hard drives occur frequently (r damaged two hard drives).
Improving management quality and attention is the fundamental way to solve such problems.
Of course, if such an incident happens around you, please do not hesitate to contact us.
