9. iStoragePro snapshot function applies Copy on Write technique on UDV VD and provides a quick and efficient backup methodology When taking a snapshot it does not copy any data at first time until a request of data modification comes in The Snapshot copies the original data to snapshot space and then overwrites the original data with new changes With this technique snapshot only copies the changed data instead of copying whole data It will save a lot of disk space e Create a data consistent snapshot Before using snapshot user has to know why sometimes the data corrupts after rollback of snapshot Please refer to the following diagram When user modifies the data from host the data will pass through file system and memory of the host write caching Then the host will flush the data from memory to physical disks no matter the disk is local disk IDE or SATA DAS SCSI or SAS or SAN fibre or iSCSI From the viewpoint of storage device it can not control the behavior of host side This case maybe happens If user takes a snapshot some data is still in memory and not flush to disk Then the snapshot may have an incomplete image of original data The problem does not belong to the storage device To avoid this data inconsistent issue between snapshot and original data user has to make the operating system flush the data from memory of host write caching into disk before taking snapshot 63 m StoragePro IRI6SASER Host
