Retention Policies and SharePoint sites
The reason why you put Office 365 Groups on retention is to ensure that the content in all the resources owned by the group is kept for a certain period.
When a group passes 30 days post-deletion, the Azure Active Directory object that represents the group is removed. This effectively breaks the link that ties all the group resources together. At the same time, instructions go to the associated workloads (like SharePoint and Exchange) to say that the group no longer exists. The workloads then check whether any retention holds exist. If they do, the content is held until the hold elapses. If not, the content is removed using the workload's normal processing (for instance, the mailbox is cleaned up by the Exchange Mailbox Folder Assistant).
Content under retention can always be accessed by a content search and export.

Regarding retention on groups IM still not really sure how it works but my guess is that by ensbling retention on a office 365 group would make sure that grouP mailbox , spbsite and files will remain! It would seem that the group itself would be undeletable but this doesn’t seem to be the case!
I’m reaching out for help here!

Sorry, if I'm being clear enough. The group I mentioned was just an example. What I'm trying to do is to understand how retention works so I can define our governance policies and also decide if we need a 3rd party backup solution or not.
Let me rephrase: As an example: A user comes to me for help recovering the content that were on a SharePoint site (with a group) that were deleted a year ago or more. I have a 5 year retention policy covering Teams, Groups, SharePoint and Exchange. Can I recover the group along with the site and team? If not, can I at least (relatively easy) recover all the files that were stored in the site?

Retention makes sure that it dont get deleted! Once its deleted, there is no way Of recovering it!
If the group is deleted, the corresponding site will remain
