Data recovery refers to the process of recovering lost data due to storage damage, user negligence or accidental interruption through remaining data fragments or backup data. In essence, it is the process of recovering lost, damaged, deleted, etc. data to a server, computer, mobile phone or storage device.
Ⅰ.What data needs to be recovered:
· Natural disasters, including fire, flood, etc.;
· Data loss caused by application software errors;
· User negligence or accidental data deletion;
· Data tampering;
II. Types of data recovery:
Physical data recovery: When our hard disk is physically damaged, we need professional data recovery personnel to recover the data.
Hard disk recovery: To recover data from the hard disk, we should seek hard disk recovery manufacturers or hard disk manufacturers. When using the hard disk, we should regularly back up important data to avoid losing important data due to hard disk damage.
Instant data recovery: When data is lost, users will be immediately directed to the backup server for complete recovery through background management.
III. Data recovery process:
1. Temporarily deactivate the affected device
When data is lost, we should immediately stop the device where the data is lost. Under certain conditions, we can retrieve damaged or lost files from the hard drive before all lost content is overwritten, but if the user continues to use the hard disk, the possibility of data being overwritten will be higher. If the data loss is caused by water, etc., the user must stop using the relevant equipment until it is checked.
2. Find the problem
When data loss occurs, we can determine whether there is a problem through the following situations:
· The system cannot recognize the hard drive or the displayed name is abnormal.
· The mechanical hard drive makes noise.
· The running speed is too slow.
3. Choose your data recovery method
Once the cause of data loss is determined, you can start to recover data. If we generate backup data regularly, the easiest way is to recover all data from all these backup data. If the user does not have a backup system, you must consider restoring the disk. We can recover data through data recovery software or relevant professionals.
4. Contact the hard drive manufacturer
After determining that the data is lost, we can consult the hard drive manufacturer, the manufacturer provides relevant help, or we can hand over the hard drive to the manufacturer for data recovery.
5. Preventive measures
After recovering as much data as possible, we must consider the cause of data loss and take measures to prevent related situations from happening again. For example, we can back up important data regularly to prevent losses caused by data loss.
6. Data recovery software
Data recovery software is a type of data recovery application software that helps us recover lost and damaged data from storage devices. Data recovery software can directly access the disk architecture, recover data by checking file architecture records, entries, and extracting data from damaged storage devices.
7. How to choose data recovery software?
When choosing the best data recovery software, we should consider the following performance parameters:
Software compatibility: First of all, the disk recovery software must be compatible with our operating system, and the program must be able to recover lost data from file systems involved in internal and external storage media, such as FAT, FAT32, exFAT, NTFS, etc.
Reliability: When choosing data recovery software, we should choose regular and big brand software. Some unknown software may steal our data or install viruses in our system to steal and tamper with data.
Performance: The key to recovering lost data is that the software can successfully retrieve all deleted and lost data and complete the recovery. Some software's actual performance does not meet the advertised effect.
