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. For details, see
“Microsoft Exchange Server 2007 recovery specifics” on page 66.
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.
To perform a point-in-time restore of Microsoft Exchange Server writer, select the
whole storage group. The transaction logs will be replaced with the backed up
logs.
To perform a rollforward restore, select only the database stores and original
location. The existing logs will be applied to the restored databases. However,
note that rollforward restore will not be possible if the point-in-time restore of the
same session was performed before.
