• Da ta distribution–Pushing copies of data to other geographic locations to make it locally
accessible.
• Da ta migration–Moving data to a new location or to one with a larger storage capacity.
To move data using a snapclone:
1. Make a snapclone of the virtual disk containing the data to be m oved. See the online help for
procedures on creating snapclones.
After the snapclone is created, the link from the snapclone to its original virtual disk dissolves, and
the snapclone becomes a separate virtual disk.
2. Create a DR group with the new snapclone–created virtual disk linked to the remote array where
you want the data to reside. The creation of the DR group replicates the virtual disk to your desired
destination.
3. Delete the source–cloned virtual disk. You have the o p tion of keeping the remote virtual disk or
deleting the remote virtual disk
4. Choose to keep remote virtual disk.
The data now resides as a new virtual disk on the remote array. It can be used as a source for another
DR group, subject to the restriction that an array can be involve d in a replicating relationship with
only one other array.
Figure 13 provides a high–level summary of the following steps that perform data movement using a
snapclone.
