Snapshots Page 601 of 677
Snapshot states
A snapshot may not necessarily be useful if the data on the target is in a bad state. You
only want snapshots of data that is in a good state. Therefore, you need to understand
when the data is in a good or bad state.
Mirror started
l State—Bad
l Description—Mirroring has started, but is not complete. The data on the source
and target will not be synchronized until the mirror is complete.
l Automatic action taken for scheduled and automatic snapshots—Scheduled
and automatic snapshots will be delayed until the mirror is complete before taking
a snapshot.
l User interaction required for manual snapshots—Wait until the mirror is
complete and the data is in a good state, then take a manual snapshot.
Mirror stopped
l State—Bad
l Description—Mirroring has stopped without completing. The data on the source
and target will not be synchronized until the mirror is complete.
l Automatic action taken for scheduled and automatic snapshots—Scheduled
and automatic snapshots will be delayed until the mirror has been restarted and is
complete before taking a snapshot.
l User interaction required for manual snapshots—Restart the mirror, wait until it
is complete and the data is in a good state, and then take a manual snapshot.
Mirror complete
l State—Good
l Description—Because the mirror is complete, the data on the source and target is
synchronized. Storage Mirroring Recover will take a snapshot while the data is in a
good state.
l Automatic action taken for scheduled and automatic snapshots—Scheduled
and automatic snapshots will occur normally.
l User interaction required for manual snapshots—Manual snapshots can be
taken normally.
