Hello Team,

We are planning to configure O365 backup using Commvault in an on-premises environment.

Please advise the hardware requirement of Media agent, access node & indexing and any other prerequisites.

We have deduplication hardware appliance that will use of Disk library.

The access node we are planning to keep in DMZ environment, so that what are the ports communication is needed from internal and o365 communication also.

And please let me know the deduplication and compression will use Commvault end or external storage appliance.

 

Thanks in advance.

Hi @AnandK 

PFB system requirement for Media agent server https://documentation.commvault.com/2023e/expert/mediaagent_system_requirements_01.html
Ports required by commvault and services associated

If you use Dedupe storage policy with commvault will manage compression and deduplication
In case the data is getting saved on any data domain the storage side dedupe will compress the data before writing the client backup.

Hi Anand,

 

Access Node requirements: https://documentation.commvault.com/2023e/expert/user_mailbox_and_journal_mailbox_access_nodes.html 

Index Node requirements:

https://documentation.commvault.com/2023e/expert/hardware_recommendations_for_index_server.html

 

And yes, Archiving feature is supported with Exchange Mailbox agent as documented: https://documentation.commvault.com/2023e/expert/exchange_mailbox_agent_architecture_user_mailbox_and_journal_mailbox.html 

 

If dedup is enabled on Hardware, then you dont need to dedupe commvault end. You can dedupe at commvault and send that to a DL that has HW dedupe enabled.
