Server data recovery refers to the use of a series of methods and technical means to restore the lost data to the server in the event of server failure or data loss. normal state process. Below I will introduce several common server data recovery methods.

1. Backup and recovery

Backup is one of the most common and most effective data recovery methods. By backing up the data on your server regularly, you can quickly recover in the event of data loss. Backup can be divided into two methods: full backup and incremental backup. A full backup backs up all the data on the server, while an incremental backup backs up only the data that has changed since the last backup. In the event of data loss, the server can be recovered by restoring the backup data.

2. RAID data recovery

RAID (Redundant Array of Independent Disks) is a technology that combines multiple hard drives into one logical unit, improving data reliability and performance. In a RAID system, if a hard drive fails, it can be recovered through data on other hard drives. RAID data recovery usually requires professional data recovery services, who can recover data from failed hard drives through technical means.

3. Data recovery software

Data recovery software is a tool that scans the hard disk or storage media to find deleted or lost files and restore them. These software can recover data lost due to accidental deletion, formatting, file system damage, etc. Common data recovery software includes Recuva, EaseUS Data Recovery Wizard, etc. When using data recovery software, you need to be careful not to write new data to the failed hard drive to avoid overwriting the original data.

4. Data recovery professional services

For some serious data loss situations, such as hard drive damage, file system damage, etc., conventional data recovery methods may not be able to recover the data. At this time, you can consider seeking professional data recovery services. Data recovery professional service agencies have advanced equipment and technical means to physically repair hard drives and extract data from damaged hard drives. However, this service is often more expensive and needs to be evaluated on a case-by-case basis.

To sum up, server data recovery methods include backup recovery, RAID data recovery, data recovery software and data recovery professional services. When implementing data recovery, you should choose the appropriate method according to the specific situation, and do a good job of data backup before data recovery to avoid irreversible data loss. At the same time, maintaining the normal operating status and regular maintenance of the server can effectively prevent the risk of data loss.
