We are currently using Metallic for Microsoft 365 applications Exchange Online, SharePoint Online, and OneDrive for Business.  This was setup by a previous employee, and I am having trouble understanding how it all works.   

 

For Exchange Online and OneDrive for Business, I would like to setup Plans to coordinate with our retention policies.  

 

For example:

Standard employees – Retain mailbox and OneDrive data for 2 years after termination.  I created a m365_2yr plan.

 

Can someone please clarify what each of these Retention settings are?

Retain deleted items for 730 days – If a user permanently deletes an email or a document from OneDrive, will it purge the deleted items after 730 days even if the user is still active?   Then once a user has been terminated or removed from backups will it retain the data for 2 years after that date? 

 

Retain backed up version for 365 days – what does this refer to?   Does it pertain to Exchange or OneDrive? 

Thank you in advance for any clarification you can provide.

Hey JP!

Welcome to managing a Commvault Cloud SaaS environment! Happy to help you get started on your journey!

First off, wanted to note that there is a great training curriculum available to review the Commvault SaaS M365 data protection works: https://readiverse.commvault.com/learn/course/84/commvault-cloud-saas-microsoft-365

I think it will help accelerate your learning curve so hope you can find some time to check it out!

 

Regarding your questions -

 

Retain deleted items for 730 days – If a user permanently deletes an email or a document from OneDrive, will it purge the deleted items after 730 days even if the user is still active?   Then once a user has been terminated or removed from backups will it retain the data for 2 years after that date? 

 

Retention is based on object level for when those specific items were deleted from a users mailbox or OneDrive. The reference to “deleted items” means it has been completely removed from the mailbox or onedrive. It has nothing to do with the “deleted items” folder in the users mailbox itself!

If a user is removed from AD this will be seen as a deletion of that MB and the 2 years will start from that point as you noted!

 

Retain backed up version for 365 days – what does this refer to?   Does it pertain to Exchange or OneDrive? 

 

OneDrive (along with Teams and SharePoint) has a concept called versioning for files where multiple versions of a file can be created as a roll back mechanism. Commvault can protect these items but allows for retention of them to be configured separately from the current version since it can end up consuming a ton of space.

Check out the documentation page here for more details: https://documentation.commvault.com/11.42/software/configuring_number_of_file_versions_to_retain_for_backed_up_items.html

 

Hope this helps!

Thanks,

Tim
