A proxy configuration interacting with Exchange Databases allows you to
execute an ESE Integrity check against the Exchange Database. For the proxy to
validate the Microsoft Exchange Database files, follow the steps below:
Install the proper version of the Microsoft Exchange Management Tools
from the Exchange installation media on the proxy computer. This will allow
you to select the proxy computer from the Use Proxy option when
configuring your Exchange subclient.
When scheduling a SnapProtect backup job, click Advanced and
ensure the Perform Consistency Check option is enabled to perform the
integrity check upon snapshot index completion.
The snapshots of the data created by the SnapProtect backup are also
available for various other operations like list, mount, unmount, delete, or
revert.
The browse operation provides the capability to see the snapshots created for
an agent, job, or a snapshot copy. The list of the snapshots displayed is corresponding
to the entity selected for the browse operation, for e.g., browsing the snapshots
for an agent will display all the snapshots created for the selected agent. You can
view volume or disk related information for the snapshots. Follow the steps given
below to browse snapshots.
From the CommCell Browser, navigate to Client Computers | <Client>.
Right-click Exchange Database and click All Tasks | List Snaps.
The Snaps created during SnapProtect operation dialog box displays a list of
all the snapshots created for the Exchange Agent. It also displays important
information about each snapshot, including the source month path, snap mount
path, the storage array, and the source client.
Click the Disk View
tab to display the snapshot name, e.g.
SP_2_79_1286222629.
You can mount any available snapshot to access the data included in the
snapshot. It is recommended that you select the option to protect a snapshot
when it is mounted, as this will ensure that the changes made to the snapshot
when it is mounted are not retained when you unmount the snapshot and the
snapshot is usable for data protection operations. Follow the steps given below
to mount snapshots:
From the CommCell Browser, navigate to Client Computers | <Client>.
Right-click Exchange Database and click All Tasks | List Snaps.
Right-click the snapshot that you wish to mount and click Mount.
Click Yes.
In the Mount Path dialog box, specify the destination client and the path on the client in the
Destination Client and Destination Path fields.
On a Windows
platform, enter a CIFS Share Name for the Agent.
If you do not wish to save
any changes made to the mounted snapshot after the snapshot is unmounted,
select Protect Snapshot during mount.
Click OK.
If you do not select Protect Snapshot
during mount,the changes made to snapshot when it is mounted will be retained
after the snapshot is unmounted and the snapshot can no longer be
used for restore.
Unmount Snapshots
Follow the steps given below to unmount snapshots:
From the CommCell Browser, navigate to Client Computers | <Client>.
Right-click Exchange Database and click All Tasks | List Snaps.
Right-click the snapshot you
wish to unmount and click Unmount.
Click Yes when prompted if you want to continue.
If the snapshot does not get unmounted,
select the Force Unmount option to mark the snapshot as
unmounted.
Snapshots can either be deleted using job-based pruning or from the list of
displayed snapshots when browsing snapshots. Data Aging can also be used to
define the retention rules and pruning of snapshots. Follow the steps given
below to delete snapshots:
Manual deletion of snapshots is not recommended. When a
snapshot is deleted, it is no longer possible to perform data
recovery operations from the snapshot copy. However, if a backup
copy was created from the snapshot, data recovery operations can
be performed from the backup copy.
Ensure that the snapshot to be deleted is not mounted.
From the CommCell Browser, navigate to Client Computers | <Client>.
Right-click Exchange Database and click All Tasks | List Snaps.
Right-click
the snapshot you wish to delete.
Ensure all snapshots with the same Job ID
are selected for a successful deletion operation.
Click Delete.
Enter the confirmation
text string, erase snapshots.
You can use the revert operation to bring the data back to the point-in-time
when the snapshot was taken. This operation overwrites any modifications to the data
since the time when the snapshot was created. This option is available if
the storage arrays that you are using supports revert.
Revert operations are supported on NetApp File Servers but
not from SnapVault or SnapMirror snapshots. You can either perform an
application aware revert or a hardware specific revert.
Review the following before performing a revert operation:
Revert operations are not supported on Windows clustered disks.
All the data stores should be manually dismounted.
When using HP EVA Clone or Data Replicator for SnapProtect backup, the revert operation is not supported.
It is recommended to verify the
contents of the backup and ensure that you want to perform a revert operation
as it is an irreversible operation.
If you plan to perform a revert operation, you
will not be able to use the associated storage policy for further
auxiliary copy operations.
Perform an Application Aware Revert
From the CommCell Browser, right-click the entity
that contains the data you want to restore, and click All Tasks | Browse Backup Data.
From the Browse Options dialog box, click OK.
Select the data you want to revert and click Recover All Selected.
From the Restore Options dialog box, click Advanced.
Select the Use hardware revert
capability if available
option.
Click OK to confirm the revert operation.
Click OK from the Advanced Restore Options dialog box.
Click OK to start the revert.
An application aware revert operation reverts
back all the volumes included in the backup.
For NetApp NFS configurations:
This operation reverts all data on the file server volume, not just the
data that is associated with the application.
A volume revert deletes all snapshots that were created
after the snapshot to which you are reverting.
If you perform a volume revert on the source for a
SnapVault/SnapMirror copy, and the snapshot to which you are
reverting was created before the most recent snap moved to
the SnapVault/SnapMirror copy, then the SnapVault/SnapMirror
copy operation no longer works.
Perform a Hardware Specific Revert
From the CommCell Console, navigate to Client Computers |
<Client>.
Right-click the subclient and click List Snaps.
Right-click the snapshot that you wish to delete and click Use hardware revert
capability if available.
Enter the confirmation
text string, confirm.
Click OK.
A hardware specific revert operation reverts back
the volume included in the snapshot.
For NetApp NFS configurations:
This operation reverts all data on the file server volume, not just the
data that is associated with the snapshot.
A volume revert deletes all snapshots that were created
after the snapshot to which you are reverting.
If you perform a volume revert on the source for a SnapVault/SnapMirror
copy, and the snapshot to which you are reverting was created
before the most recent snap moved to the SnapVault/SnapMirror
copy, then the SnapVault/SnapMirror copy operation no longer
works.
Snapshots may be deleted from the array due to factors like low disk space on
the array, number of snapshots exceeds the threshold etc., and the jobs corresponding
to these deleted snapshots can no longer be used for any data recovery or backup
copy operations. You can use the
nRunSnapRecon
registry key to start snap reconciliation to check for missing snapshots once in
every 24 hours and marks jobs corresponding to the missing snapshots as invalid.
Pause points allow Exchange system resources to be made available periodically to
other processes (e.g. send and receive e-mail messages) during the following:

SCSI Reservation
SCSI reservation can be enabled for SnapProtect backup
for all the agents. Use the registry key
nSCSIReserveForSnap
to enable SCSI reservation. Enabling SCSI Reservation prevents other applications
(SCSI3 compliant) from using the reserved SCSI Device (i.e. the mounted
snapshot).
If this option is enabled and the hardware
does not support this type of operation, subsequent data protection
jobs may fail.
The Pre/Post commands for SnapProtect backup
can either be executed on the proxy or the source computer. You can use
the Pre/Post Process tab of the Subclient Properties dialog
box to select where you wish to execute the Pre/Post commands. SnapProtect
backup supports Pre/Post commands for the agents that support it.
Use of Pre/Post Snap commands is not supported when using Data Replicator as the storage array.
For more information on using the Pre/Post
commands, see
