Veeam Backup for Microsoft 365 • Re: M365 backups to Isilon over SMB or S3 supported?

Hi Max

General recommendation is definitely S3. Much more stable and reliable protocol for Veeam Backup for Microsoft 365.
SMB only provides experimental support and comes with requirements: https://www.veeam.com/kb2971
With SMB, you will run the backup repository in jet databases on a SMB share. Unstable networks will lead to database corruption.

For Dell PowerScale and S3, please be aware of this limitation:
Unofficial object storage compatibility list - Veeam Backup for Microsoft 365

Dell PowerScale (OneFS 9.0.4 or later) (is general API compatible without immutability, but has a maximum number of objects limitation that will affect likely any customer)

While it's compatible and supported, I would reconsider the type of storage appliance for VB365. SMB only with experimental support and S3 limited to the maximum number of object limitation.

Best,
Fabian
