Trying to keep up with RegulatoryCompliance Requirements

Solution: Snapshot images of data that can be scheduled

This meets a broad range of new regulations which require point-in-timebackup and recovery information

Data can be tracked, protected and accessible on demand

In the US, regulations such as SEC 17a-4, StarBox section 404 andHIPPA, for example, are driving new mission-critical storage strategiesbased on snapshot capabilities

















Creating Snapshot Virtual Disks




Before Creating a Snapshot VirtualDisk

Destination of the repository is based on the free capacityavailable in the disk group – Snapshot repository requires a min of 8MB of free capacity

You can choose a preferred creation path: – Simple or Advanced if you have the 8MB –

Advanced if you have under 8MB NOT valid source virtual disks

– Snapshot repository virtual disks, snapshot virtual disks, targetvirtual disks and virtual disks participating in a virtual disk copyare

You cannot create a snapshot of a virtual disk that contains

unreadable sectors No I/O requests are permitted on the source virtual disk while the

virtual disk snapshot is being taken

Note: In a Windows Clustered Config, the Snapshot must be mapped to thecluster node that owns the source virtual disk ensuring the cluster node

correctly recognizes the snapshot































Creating a Snapshot Virtual Disk – Simple Path

1. Configure tab2. Select Create Snapshot Virtual Disks













About Advance Path

You have control over:

– Snapshot virtual disk name and snapshot repository virtualdisk name

– Capacity allocation

–Percent full

– Snapshot repository virtual disk full conditions

There’s No Time to Stop and Take aBackup

Solution: Snapshot and Virtual DiskCopy

Creation of a disk staging areabefore moving to tape

This removes the copy-on-writepenalty while you are doing thebackup with Snapshot only

Reduces the impact to theproduction system of a lengthydirect disk-to-tape backup

Ability to keep several backupsonline for fast recovery

*Snapshots can also be used as the source virtual disk for backup to tape – insteadof backing up the master virtual disk, backup the snapshot instead

Solution: Snapshot Virtual Disk Its PiT capabilities allows an IT admin to go back in time if a new

application release does not go as planned



















Virtual Disk Copy




Virtual Disk Copy Highlights

The preferred method for creating a virtual disk copy is to copyfrom a snapshot virtual disk.

– This allows the original virtual disk used in the snapshotoperation to remain fully available for read/write activity whilethe snapshot is used as the source for the virtual disk copy

operation The source virtual disk can be:

– A standard virtual disk

– A snapshot virtual disk

–A source virtual disk of a snapshot virtual disk

The target virtual disk can be:

– A standard virtual disk

– The source virtual disk of a failed or disabled snapshot virtualdisk



























Before Creating a Virtual Disk Copy

A virtual disk copy overwrites data on the target virtual disk.** Before starting a virtual disk copy, ensure that you no longerneed the data or back up the data**

When a virtual disk copy is started, all data is copied to the targetvirtual disk – the source virtual disk permissions are set to read-

only until the virtual disk copy is complete To prevent error messages, do not attempt to access a source

virtual disk that is participating in a virtual disk copy while thevirtual disk copy is in progress


















Creating a Virtual Disk Copy

1. Go to the Configure tab and select Create Virtual Disk Copies.

Note: Before you create a full copy of a source virtual disk, stop any data access (I/O) to thesource and target virtual disk so that the source virtual disk has a stable version of the data

to be copied.

Additional Premium FeatureFunctions






Increasing the Snapshot RepositoryCapacity

You can increase the snapshot repository capacity: – Using free capacity available on the disk group of the

snapshot repository virtual disk

– Add unconfigured capacity to the disk group of the snapshotrepository virtual disk – use this only when NO free capacityexists on the disk group

You cannot increase the capacity of a snapshot repository if thesnapshot repository has any of these conditions:

– The virtual disk has one or more hot spare drives in use

– The virtual disk has status other than Optimal

– Any virtual disk in the disk group is in a state of modification – The controller that has ownership of the virtual disk is adding

capacity to another virtual disk

– There is not free capacity on that disk group

– There is no unconfigured capacity available to be added






































1. Go to the Modify tab and select Modify Snapshot Virtual Disks













2. At the Modify Snapshot Virtual Disks window, select ExpandSnapshot Repository














2. Select the snapshot repository virtual disk you would like toexpand. Click Next.











3. The Expand Snapshot Repository – Increase Capacity window provides thecurrent capacity of the source virtual disk and the snapshot repository. Select theamount of capacity you would like to increase the repository by. Click Finish.

If necessary, free capacity can be added to this virtual disk group by adding anunassigned drive as well.



















4. A notice will then pop up, advising of the time it will take toincrease the capacity of the snapshot repository and is notcancellable once it starts.

– The snapshot and source virtualdisk will remain accessible.Select Yes to continue.

5. The Expand Snapshot Repository – Started window will confirmthat the process of increasing capacity to your snapshot repositoryhas begun.























Reusing Snapshot Virtual Disks

You can disable a snapshot when you no longer need it (such aswhen the back up is complete).

You can re-create and reuse it the next time you need it










Reusing Snapshot Virtual Disks -Disable

1. Go to the Modify tab and select Modify Snapshot Virtual Disks













2. At the Modify Snapshot Virtual Disks window, select DisableSnapshot Virtual Disks














3. At the Disable Snapshot Virtual Disks screen, select thesnapshot virtual disk you would like to disable. Click Disable.

4. A pop-up window will then ask you to confirm.Type yes and OK.





















Reusing Snapshot Virtual Disks – Re-creating the Snapshot

1. Go to the Summary tab and select Disk Groups & VirtualDisks link to ensure that the snapshot virtual disk is in disabledstatus.

Note: Follow the additional instructions for your OS. Failure to follow theseadditional instructions can create unusable snapshot virtual disks.





















2. Go to the Modify Tab and select Modify snapshot virtual diskslink.

3. Select Re-create SnapshotsVirtual Disks






















4. Highlight the snapshot to re-create and select the Re-create button.

5. A warning window will explain that if the virtual diskwas not already disabled, re-creating it will disable itfirst - making the point-in-time image unusable. Typeyes and OK to confirm it is ok to continue.























6. A confirmation window Re-create Snapshot Virtual Disks willopen to inform you that the snapshot was successfully re-created.

Recreating a snapshot repository virtual disk uses thepreviously configured snapshot name and parameters..















Managing Virtual Disk Copies

The Manage Virtual Disk Copies task screen is accessible fromthe Modify tab and allows you to recopy, stop the copy process, setpermissions, set priority or remove virtual disk copies.

The following slides will review some of the tasks accessed from

the Managing Virtual Disk Copies.

–


















Managing Virtual Disk Copies – Stopping a Virtual Disk

From the Manage Virtual Disk Copies task screen, select thevirtual disk copy operation that is in process and that you would liketo stop. Click Stop.

Only one operation can be stopped at a time. You will be asked to

confirm that you would like to stop the copy operation. Click Yes.

–



















Managing Virtual Disk Copies – Recopying a Virtual Disk

From the Manage Virtual Disk Copies task screen, select thevirtual disk copy that you would like recopied and click Recopy.

Only one operation can be recopied at a time.At the Recopy dialog box, set the priority setting,type Yes and click OK.





















Creating a Virtual Disk Copy for aMSCS Shared Disk

Create a snapshot of the virtual disk and then use the snapshotvirtual disk as the source for the virtual disk

When creating a snapshot virtual disk, map the snapshot virtualdisk to one node in the cluster

– Mapping the snapshot to the host group or both nodes in the

cluster may cause data corruption by allowing both nodes toconcurrently access data

Note: Directly creating a virtual disk copy for an MSCS shared disk, instead of a snapshot virtualdisk, will fail with the following error – The operation cannot complete because the

selected virtual disk is not a source virtual disk candidate.
