Description
|
|
Retains the existing transaction logs. Exchange replays the
transaction logs that are part of the restore, followed by any
transaction logs that currently exist.
|
|
Restores the database and replaces only the transaction logs
that existed at the time of backup.
|
Temporary location for log files
|
Enter a location where the associated log files are kept until
the database is restored. The default location is c:\temp . If you choose to restore storage groups,
NetBackup creates a subdirectory in c:\temp for each storage group. It keeps log
files for each storage group in the corresponding subdirectory.
If Commit after last backup set is
restored is selected during the restore, Exchange applies to the
database. Then it applies the current log files. After the restore
is complete, Exchange deletes the log files from the temporary
location (including any subdirectories).
Note:
|
Make sure the temporary location for log
files is empty before you start a restore job. If a restore job
fails, check the temporary location (including subdirectories) to
make sure any previous log files from a previous restore job were
deleted.
|
|
|
Dismounts the database(s) before the restore begins. This option
dismounts all of the databases in the storage groups that you want
to restore, even if a database is not selected for restore. By
default this option is not selected.
This option also sets the Database can be
overwritten by a restore flag in Exchange 2007.
Note:
|
Use this option with caution. Ensure that
you selected the correct database to restore before you choose to
dismount it with this option.

|
|
This option should only be set on the last job of a multi-job
restore. This option enables the restore operation to play through
log files and roll back any uncompleted transactions. If this
option is not selected, the database needs to be mounted manually
after the restore.
If is selected when an intermediate backup is applied,
you cannot restore further backups. You must restart the restore
operation from the beginning.
