Fujitsu ETERNUS DX100 S3 - Figure 51 Targets for the Multi-Copy Function; Figure 52 Multi-Copy

● Multi-Copy
Multiple copy destinations can be set for a single copy source area to obtain multiple backups.
In the multi-copy shown in Figure 51, the entire range that is copied for copy session 1 will be the
target for the multi-copy function.
When copy sessions 1 and 2 are EC/REC, updates to area A in the copy source (update 1) are copied
to both copy destination 1 and copy destination 2.
Updates to areas other than A in the copy source (update 2) are copied only to copy destination 2.
