Database backup file recovery case under LINUX

Case:
The customer is the company’s network management. When doing data migration for the server, deletes the compressed package of a backup with the MySQL library file. The compression package is very large, there are more than 1G.data.

Solution:
The storage file system is EXT3.Due to the characteristics of the EXT3 file system, files will inevitably produce a large amount of fragments, and ordinary recovery software is powerless.Data is very important. The web management itself has tried to use software to be unable to recover and failed.Customers contacted a number of recovery and recovered defendants that the defendant could not recover. After the customer found us, he began to recover. Since we have a deepening of the low -level research of the Linux file system, we will quickly position the file, rewrite the I node, directly perform data extraction, and verify the verification.After that, the file is normal, and the data is 100%recovered successfully.
