Microsoft Exchange Server Writer Recovery
Specifics
This section provides specific information on the instant recovery
point-in-time, and rollforward restore of the Microsoft Exchange Server
Writer.
With Microsoft Exchange Server 2003, you can restore a whole storage
group or individual stores only to the original location.
With Microsoft Exchange Server 2007 writer, you can restore a whole
storage group or individual stores to the original and to a different
location. See “Microsoft Exchange Server 2007 Recovery Specifics” on
page 58 for details.
If you restore to the original location, note that restore will fail if you do
not select all objects residing on the target volume to be restored. If for
example you have four stores and transaction logs on the target volume
to be restored and would like to restore only one store, the restore fails
since it can restore only all objects residing on the target volume. Due to
this fact, the following configuration scenarios are possible when
restoring Microsoft Exchange Server Writer:
• Transaction logs and database stores are on the same target volume.
You cannot select only the database stores for instant recovery in the
GUI. If the transaction logs and/or database stores are lost, the whole
storage group (or all objects residing on the target volume) should be
recovered.
In this case, you can perform only point-in-time restore. The
transaction logs will be replaced with the backed up logs.
• Transaction logs and database stores are on different target volumes.
You can select only the database stores for instant recovery in the
GUI. If a data store is lost, it can be recovered separately providing
that it resides alone on the target volume to be recovered. Otherwise,
all stores residing on the target volume must be selected for restore. If
the transaction logs are lost, the whole storage group should be
recovered.
In this case, you can perform both point-in-time or rollforward
restore.
