Feature Request: Back up all Teams Data

[cl1234]

So when we bought licensing for our clients and created a backup job that says to back up Teams, we were under the impression it was backing up Teams.
upon my client requesting we look for a chat between two employees, I could not find this and created a case and found out that even though we are paying Veeam to back up our 365 data, they don't actually back up all the data. This is absolutely ridiculous - my client is furious as they are paying us to back up their data.
So this needs to be added in ASAP - if I select to back up exchange, sharepoint, onedrive, and teams, it "MUST" back up all this data.

AFAIK it is not technically possible to backup certain chat types at this time due to a Microsoft limitation. Am I remembering this right @Mike Resseler ?

Technically it is possible, but until recently, the cost was very high because there is no deduplication into those messages. So imagine a chat between 10 people with in total 50 messages, we would need 500! (paid) API calls to protect that data. (And imagine you have a 1 to the entire organization chat...) Today, we have a private beta of the API that will allow for deduplication so we can start testing this feature. But I don't have a timing at this point in time.
