absrtact : The traditional data backup technology has the problem of backup window, recovery time objective RTO and recovery time RPO too long, which can not meet the requirement of data protection for enterprise critical business, thus the data snapshot technology is produced. In this paper, the concept of snapshot technology, characteristics, implementation technology and the status of the development of

transaction holds the mutex until the end of the transaction is released, and the mutex is not affected by the transaction isolation level. Isolation and concurrency are the relationships that have been extended. In SQL Server, mutexes and arbitrary locks are incompatible, and at the same time, only one transaction holds the mutex on the same data row, that is, the write operation is sequential and cannot be concurrent. Choosing a transaction isolation level does not affect the locks acquired t

LogicalVolumeManager (LVM) provides the "snapshot" (snapshot) function for any LogicalVolume (LV) to obtain the state consistency backup of a partition. When backing up a file in a certain state, an application may be accessing a file or database. This means that the file is in a state during backup, after the Logical Volume Manager (LVM) is backed up, it provides the "
