System requirements: Minimum Office 365 subscription

[Gustav]

I've searched all over to locate what "minimum" (= cheapest) Office 365 subscription is needed for the account servicing Veeam Backup for Office 365.

As to my finding, an Office 365 F3 is the simplest, thus cheapest subscription:

This should be listed under System Requirements for Veeam Backup for Office 365.

Hi Gustav,

We support multiple subscription types. F1 works as well for example but for the service account, it's all a matter of assigned permissions according to our system requirements.

Thanks, and yes, many subscription types are possible; that's not my point.
What is missing, is information about the cheapest subscription that will allow Veeam Backup for Office 365 to operate.

We started with a vacant E3 subscription, but that was later needed for other purposes. Thus I was about purchasing one more for Veeam, but a little research revealed, that an F3 is only 25% of the cost for an E3 subscription.

I can't see how an F1 subscription will do, as it doesn't seem to allow access to Exchange (mail and calendar) which, I guess, is mandatory for most organisations.
But, to be honest, I can't decode what you mean with the sentence: F1 works as well for example but for the service account.
Could you elaborate a bit on that, please?

Hi nielsengelen,

please can you provide the requested information?

I´ve to answer the same question as Gustav to one of our costumer because of we´re facing performance issue´s because of throttling by Microsoft and I´m under pressure to deliver this information that we can quickly create our first full backup for the new VBO365 environment in an accapteble time window. Our first try with one service user account we had to stop after 30 hours of runtime and VBO365 has backuped only 500 GB until this time. Costumer Environment size is approximately 450 Users with 3000 object at all und approximately 2 TB of data. He has two WAN Connections with 200 and 150 Mbps. We use Modern Auth with support of Legacy Auth Protocols and each Office / M365 Ressource Type has it´s own backup job (Exchange, Sharepoint, OneDrive and Teams) as Michele advised it in it´s current (v5) technical deployment and configuration whitepaper. To resolve it we would like to start with the first bunch of 8 auxiliary Azure AD service account users to get the data faster and if the 8 users are not enough then we´ve to create the next bunch of 8. Because of this the minimum required Office / M365 license / subscription type is important and can be quickly a economimic factor with multiplication potencial.

In the current Veeam Office 365 Help Center "License and License Types" section you´ll find the following note:
"For more information on Microsoft licenses required to back up user mailboxes, public folder mailboxes, SharePoint and OneDrive for Business objects, see Considerations and Limitations."

But if you look at the linked "Backup" section under the page of "Considerations and Limitations" you didn´t find the exact information about this. I´ll request a expansion to this importent point over the "send Feedback" link too. As Gustav mentioned before, it seems to me too that Microsoft 365 F1 Subcription isn´t sufficient to backup the data of all Office/365 Ressources because:
the Subscription type has no Exchange Online License and User with this Subscription type cannot have Sharepoint Administrator Role. I think Microsoft 365 F3/Office 365 F3 Subscription type is the minimum required subscription type, but I would like to have certainty. Would assume that there are experience values from other customer environments for this.

I am astonished that this topic seems to be relevant only for a small group of people.

Thanks in advance!

Hi, I think there is a misunderstanding:

There is no need to have M365 licenses for the additional backup accounts! These users only need the correct permissions and only backup-source users need to be licensed (e.g. you cannot backup a user's mailbox if the user you want to back up has no Exchange license).
There are only some use cases where you need a license on the backup user (where this would only be the main user with which you add the organization). Major thing would be e.g. for the backup of MS Teams you'll need a license on the backup user (Exploratory experience would be enough)

Also in concerns of speed: If there is no requirement for the legacy auth protocol, I recommend to connect the organization with Modern Auth-Only - there are several API operations which run faster that way.

Hi Stefan,

many thanks for Clarification and the performance tip for Modern Auth only!

Best Regards

Hi, I think there is a misunderstanding:

Yes, I indeed have misunderstood this, can't tell why.
I removed the license I had assigned to Veeam O365 and started the backups. They ran successfully.

Thank you for the clarification!
