Overview of Snapshot (Snapshot) technology development

a viable option, but applications such as databases directly choose to use logical volumes to implement snapshots because they cannot be managed by snapshot technology at the file system level. In general, there is no need to implement snapshots at the application layer, which can be implemented using the underlying file system or volume Manager interface for backup mechanisms, but requires a temporary pause to ensure

architecture, so it was necessary to consolidate different protocols to simplify the architecture. In support of Multi-Protocol architecture, storage virtualization can be assisted to achieve the goal of unified management. VTL is a backup-to-disk scenario that enables organizations to improve backup efficiency without changing existing architectures and management mechanisms by emulating the disk as a tape. Virtualization improves space utilization NetA
