Creating Clones for Backup
Use the CLONE utility to duplicate the data on any unpartitioned single-disk unit,
stripeset, mirrorset, or striped mirrorset in preparation for backup. When the
cloning operation is complete, you can back up the clones rather than the
storageset or single-disk unit, which can continue to service its I/O load. When
you are cloning a mirrorset, CLONE does not need to create a temporary
mirrorset. Instead, it adds a temporary member to the mirrorset and copies the data
onto this new member.
The CLONE utility creates a temporary, two-member mirrorset for each member
in a single-disk unit or stripeset. Each temporary mirrorset contains one disk drive
from the unit you are cloning and one disk drive onto which CLONE copies the
data. During the copy operation, the unit remains online and active so that the
clones contain the most up-to-date data.
After the CLONE utility copies the data from the members to the clones, it
restores the unit to its original configuration and creates a clone unit you can back
up. The CLONE utility uses the steps shown in Figure 45 to duplicate each
member of a unit.
