Hi Vaulters,


Hope everyone is doing well.

We have a new commvault platform that will be installed, and we’ve been asked by our storage team what are the LUNs size that are needed for backed up data. In order for them to create and map them to our MediaAgents.


So, it’s a sizing question. Are there any recommendations per Commvault or utility that can be used to help us decide what’s the best storage configuration will fit our needs ?


Knowing that our platform will back up multiple workloads : VMs, FileSystems, DBs (SAP HANA), Mailboxes (Exchange), Active Directory ...etc.


Any recommendation from you guys would be much appreciated.

Hi @Sebastien Merluzzi,


Thanks a lot for your feedback.

Is there anything more precise ? In which we can specify the type of workload to be used (DB, VMs, Mailbox…etc.).


Kind regards.

We came across a Design Tool which seems to be a good start.

Following the below screenshot:


Can anyone give us examples on how to set up the “Retention” part, for example, having a weekly full and daily incremental with a retention of 15 days and 1 cycle. How can this be setup on the tool ?
