Case:
The server is 3650 of IBM and stored as a type of EMC.The server is stored through the optical fiber channel to use a 2TB LUN.The virtualization system is ESX4.1. There are three virtual machines on this server, a Kingdee K3 ERP system, an OA system, and a IPSCAN server.
Solution:
First, the snapshot file deleted deleted by the ESX system. Since the snapshot file is growing in real time, a large number of fragments are scattered in the VMFS volume, and the two virtual disks of this case are quite large.The difficulty of data recovery has increased.However, the VMFS file system data recovery software using the independent ESX/ESXi: Frombyte Recovery for ESX internal version of the Bedug features the fragments of all deleted snapshot files. After the merger, the snapshot file is successfully recovered.Then use the ESX snapshot file to write a tool to write these two express photos into the original virtual disk. At this time, the status of the file is the latest time.The backup file is normal. This is the problem of the database itself. Before the data is lost, there is a problem with this database.Once again, the Database of Kingdee K3 is logically repaired, and the data has been reproduced.
