We have tested the Snapshot Feature. Very nice, a fast backup-Copy can be
generated. But how can i get back the hole old state in time of
snapshot ? Copy from the second snapshot-volume goes to long. We can
override the changed data.
We will use this during a migration, and we will be able to go back to
the old state. So we will make a picture of the old state, and we will go
back if the migration fails. We have about 100 GB Data on this volume.
