A restore obtains backup copies of Exchange databases and
transaction logs and returns them to the Exchange Server.
Restore processing: Actions
To perform restore
processing, Data Protection for Microsoft Exchange requires
that the Exchange Information Store service must be running. However,
the databases that are being restored must be dismounted.
You
can use Data Protection for Microsoft Exchange to
restore mailbox databases to a recovery database. With Microsoft Exchange Server, you can also
use the item recovery feature of the Exchange Client to recover messages
and folders that are accidentally deleted. Exchange Server also provides
a deleted mailbox feature to recover deleted mailboxes. For more information,
see your Microsoft Exchange Server documentation. Data Protection for Microsoft Exchange also
has a Mailbox Restore feature that enables mailbox and item level
restore operations by using a batch or drag-and-drop selection method.
The restorefiles command
restores the .edb and .log files
from specified Data Protection for Microsoft Exchange VSS
backups into a specified directory. This action enables individual
mailbox recovery products from other vendors, including mailbox recovery
tools to be used. You can run the restorefiles command
from a system without an Exchange server that is installed to a specified
directory on the same system as the Exchange server. For more information
about this command, see Restorefiles command.
When
a VSS restore operation is initiated, the Data Protection for Microsoft Exchange software
completes the following tasks:
- Validates the state of Exchange server objects.
- When you use the Data Protection for Microsoft Exchange graphical
user interface, you are prompted whether to dismount the databases
you are restoring into.
- Begins a session with a Tivoli® Storage Manager server.
- Verifies that the VSS service is running and that the Exchange
writer is available.
- The Tivoli Storage Manager VSS
requestor performs the VSS snapshot
restore preparation stage.
- The Tivoli Storage Manager VSS
requestor restores the backup data.
- The Tivoli Storage Manager VSS
requestor marks the restore as complete in VSS.
- Optionally, mounts databases to run recovery.
Mailbox restore processing: Actions
When a
mailbox restore operation is initiated, the
Data Protection for Microsoft Exchange software
completes the following tasks:
- Starts a session with the Tivoli Storage Manager server.
- Queries the Tivoli Storage Manager server for
a list of available backups.
- Selects an appropriate backup that is based on user input.
- Creates an Exchange recovery database on a specified directory.
- Restores the selected backup into the Exchange recovery database.
- Copies individual mailboxes or individual mailbox items from the
Exchange recovery database into the original mailbox or other location.
- Removes the Exchange recovery database and all associated files.
Mailbox Restore Browser
When
the
Mailbox Restore Browser is started, the
Data Protection for Microsoft Exchange software
completes the following tasks:
- Detects if there is an existing recovery database. If a recovery
database is found, the browser automatically connects to that database
and displays the database contents. If there is not an existing recovery
database, start the mailbox selection dialog. In this dialog, the
user selects a mailbox or database to browse.
- Starts a session with the Tivoli Storage Manager server.
- Queries the Tivoli Storage Manager server for
a list of available backups.
- Selects an appropriate backup that is based on user input.
- Creates a recovery database, and restores the selected backup
into the recovery database.
- Connects to the recovery database and displays the contents.
After you select the items and they are restored, you can, optionally,
remove the recovery database.
