There are different ways of creating a mirror on Solaris, and the
answer depends on how you do it.

SDS/LVM and non-flashsnap VxVM do not support incremental
re-establishes. Flashsnap licensed VxVM does.
Of course, both UFS and VxFS support temporary, consistent "snapshots"
at the filesystem rather than disk level. You might prefer to backup a
filesystem snapshot rather than mess with the disk mirroring stuff.
