Hello and welcome to the second part of this video series
on SAP HANA Data Protection using HPE and Commvault.
My name is an Anshul Nagori.
I am a World Wide Technical Marketing Engineer with HPE storage.
And today we're going to talk about SAP HANA data snapshots
using HPE and Commvault.
Let's begin in the previous video,
we saw how Commvault enables streaming backups for SAP HANA data
and logs using the backend API.
While these backups offer complete data protection,
the time taken to perform a backup and a restore
can go up to several hours depending on the size of the database,
the amount of changes that happen between two backups
and the available bandwidth on the underlying network.
Commvault solved this problem
using the IntelliSnap technology.
On one hand, it integrates with SAP HANA
to achieve application consistency,
and on the other hand,
it integrates with HPE GreenLake for block storage
to take storage snapshots.
Application consistency in SAP HANA is achieved
using the prepared and confirmed statements.
In between these two steps,
Commvault instructs the underlying storage array
to take snapshot of the data volume.
This creates a successful entry in the SAP HANA backup catalog.
This entry can then be used at a later point of time
to restore the SAP HANA instance to a desired state.
The biggest advantage of this approach
is that HPE GreenLake for block storage takes just a few seconds
to snapshot the data volume and this is independent of the size of the database.
This reduces the backup and restore durations
and hence the recovery point and time objectives.
The second advantage of this approach
is that Commvault can move these snapshots
from HPE GreenLake for block storage
to HPE StoreOnce, which offers industrial leading source site deduplication.
Commvault automates the entire backup lifecycle
of an SAP HANA instance
using the IntelliSnap as well as streaming backup technology
for data as well as logs.
Now let's take a look at a demo of this technology.
This is the same SAP HANA instance
as we saw in the previous video.
To start with an IntelliSnap, we first create a plan,
select Server backup,
give a Plan name
and click on Add to add the store catalyst store as its destination.
The next step is to add the underlying HPE storage array,
so that Commvault can start taking snapshots on it.
So click on Infrastructure, click on Arrays, click the Add button
and in the Snap vendor dropdown list, you select HPE storage as the option.
I need to give the Array name
and the IP address or host name as the control host,
I also need to mention the credentials for logging into the array.
Then we select the Commvault server as the MediaAgent
and click Next,
again keep everything else to default
and save this configuration.
The next step is to go to the database and start taking snapshots.
So we select the database, we need to add a Subclient to it
which will enable IntelliSnap backups.
Click on Add subclient, give it a name.
We select the plan that we just created. That's HANA_Snaps and click on Ok.
This links the plan to the database.
Next, we enable snapshot management, by selecting HPE Snap engine.
You select the HANA server as the access node for snapshots.
And the last step is to select the database and click on Back up.
This starts an IntelliSnap backup
for the SAP HANA instance.
You can see the job details
and from the command line, you can even look at the logs
where the initial global INI parameters are getting set.
This is a one time operation
and any subsequent IntelliSnap backup starts with a command right away.
You can verify this from the SAP HANA Cockpit or Studio screen
by going to the Backup catalog and refreshing it.
Here we can see a snapshot backup in progress
which will take just a few seconds to complete.
And after a while, if you just refresh the screen, you'll see
a snapshot backup is in completed state.
This is how you can take an IntelliSnap backup
with Commvault and HPE for any given SAP HANA instance,
In summary, HPE and Commvault offer a holistic solution
to protect SAP HANA using back in paste
streaming backups and snapshot based IntelliSnap backups.
These two technologies enable you to get a low RPU and RTO for your environment
and thus giving you the ultimate ability to run your businesses efficiently.
