Immutable Backup Images

We currently have a ‘dual-site’ scenario - each with 2 media agents attached to a Dell/EMC ME4084 disk library.  Commvault is configured with a CommCell in each site - with failover enabled.  Backup images are secured in each local site and then a secondary copy replicated to the alternate site.

As I am sure is common - the questions are being raised around immutable backups in this CV environment

I have seen documentation regarding immutability of cloud based backups, and discussions of WORM technology - but am unsure as to what applies to us here with our CommVault / disk library configuration.

V11 SP20

Any input appreciated…..

You can absolutely apply WORM to disk/network targets - data will be held until the retention is met. Retention cannot be lowered and jobs cannot be deleted.

https://documentation.commvault.com/commvault/v11_sp20/article?p=13938.htm

Just note the caveats, as it's generally a one-way street (which is the entire point :blush: ).

 

Also, be sure to check/enable ransomware protection which will help disable tampering with your disk library from malicious applications.

It seems like that Cloud is not a library destination for you at the moment. So I would suggest reading the papers shared previously but also taking a detailed look at the Authentication, authorization and accounting aka (AAA) framework that will give you a good understanding of what can and has to be done in your environment.

Damian,

Most helpful - exactly what I was looking for !

The Ransomware protection was already enabled on the 4 media agents attached to the disk libraries - but good to point out….

Regards,

Andy.

Awesome!

 

Additionally, there is a great security assessment dashboard for Command Center in FR20 and later as well. It covers other best practices of things you can do to better secure the environment. Here is a quick video on it and here is the documentation. I think it's been improved beyond FR20 but I thought it may be helpful for you.
