摘要:
When a snapshot of data is taken, it is after a write request comes from the host equipment that old data on the source-side magnetic disk to the snapshot-side magnetic disk; therefore, it takes a long time before new data is actually written in the source-side magnetic disk. To overcome this problem, by analyzing data update information, and from a result of analysis, by deciding an area that has high possibility of receiving a request to write data, and having data of that area previously copied to the snapshot-side magnetic disk, it is possible to take a snapshot very quickly.
摘要:
In a storage switch to control a snapshot operation in the file unit, the delay in the writing operation of a host due to a data saving operation is prevented. In a snapshot acquiring method, the memory usage in a switch is reduced to create a snapshot. The storage switch includes a function to create a snapshot of a file. To prevent occurrence of delay due to the data saving operation, a mirror of source data as a snapshot target is kept in a source volume in any situation or according to a predetermined condition with synchronization established between the mirror and the source data. In the creation of the snapshot, the mirror data is used. By creating the mirror data in sequential positions in the source volume, the positional correspondence between the source side and the snapshot side is simplified.
