Case One: Misoperation Causing File System Anomaly
In December 2017, a certain AI startup company encountered a major crisis. During the expansion of the cloud hard disk where important data was stored, the operation personnel made an incorrect operation that led to a file system fault of the hard disk, making data inaccessible.
The problematic disk had multiple partitions. The company lacked experience in file system repair for multi-partition disks and dared not attempt repairs recklessly, for fear of causing further data damage. Fortunately, the company used the data arch service to protect the disks where important data was stored. They immediately started a restoration, and all data was retrieved in less than half an hour.
Case Two: Rapid Data Recovery
During the “Wannacry” virus outbreak in May 2017, a large number of Windows hosts worldwide were invaded. Important files of enterprises were encrypted, with high ransoms demanded for the decryption and restoration of files. A cloud server of a certain print company was also attacked by the virus, with customer print files getting encrypted.
Previously, this print company had deep cooperation with UCloud Global, choosing to use the data arch to provide real-time continuous protection for customer data. After confirming the data pollution time point, the company used the control panel to restore the data to the point before the data pollution, ensuring the integrity of customer data to the greatest extent.
Case Three: Mistaken Deletion of Database Table
In April 2018, a development engineer of an Internet company accidentally deleted a table in the production environment database while operating the database. Since the database backup cycle was long, using the backup for restoration would result in a significant loss of data. Lacking practice in using backup to restore data, the company directly attempted to use the data arch service to roll back to the point before the deletion, recovering the lost data in less than ten minutes.
Traditional database recovery methods rely on backup. If the backup is missing or corrupted, even professional database recovery companies cannot guarantee the retrieval of all data. In 2017, Gitlab experienced a long service interruption and lost data for as long as 6 hours because of mistakenly deleted data. Compared with these, the data arch minimizes the impact of data deletion.
