Microsoft Graph Metered API Usage and Charges

[mohamed.UBX]

Got unexpected $700 USD spike in Azure bill related to Microsoft Graph metered API services. It looks like Veeam’s use of the Graph API to backing up Microsoft Teams messages is generating high volume of API calls and cost.

I’m trying to understand how to estimate or monitor the actual number of API calls Veeam is making and how many Teams messages are being backed up. Right now, I can only access Teams usage reports for the last 180 days, but the teams usage count shown there doesn’t seem to match the billed usage. There seems to be a disconnect between what’s being backed up and what’s actually being billed by Microsoft.

Hi Mohamed,

For backup purposes, Veeam is using payment model B.

To estimate the cost of the first full backup, you can get the number of your channel messages from the Teams usage report and multiply it by $0.00075 per message.

Thanks!

Hi Polina,
I suggest NOT suggesting this estimation to customers because it is often way off of the actual amount that either
- Veeam somehow generates through their API uses or
- Microsoft charges.
You already know veeam-backup-for-microsoft-365-f47/team ... 83260.html, and you can find cases outside this forum, too.

We too have the problem of excessive API costs that are neither remotely explainable with the amount of objects that Veeam BfMS365 claims in the GUI reports and in the log files nor with the number of channel messages from the Teams usage reports.

Hi Thomas,

May I ask you to share your related support case ID?
