How to limit growth of a volume synced using Azure File Sync with cloud tiering enabeld

Dalton Rafael Belo 40 Reputation points

I have a 1TB drive installed on a server, used internally, that will function as an Azure File Sync server. The data I've migrated to this server is about 2,5 TB. Almost all of the data is already tiered. ( I use "if less than 95%, tier the file" configuration).

So Is ther some way where I can limit the Data locally? Something ike using FSRM quotas or somethin like that? That is, considering the scenario where cloud tiering is enabeld.

Im trying this because I want to avoid a situation where my users, knowing that their data is being tiered, start to upload a lot of files indefininitely.

    Azure File Sync doesn't offer built-in quota functionality. If you wish to control the amount of storage a user can use, this would have to be done on the local file system. You can still enable cloud tiering if you have a volume-level FSRM quota. Once an FSRM quota is set, the free space query APIs that get called automatically report the free space on the volume as per the quota setting.

    Also, it's important to note that the volume free space percentage used for tiering calculations is the percentage of logical free space, not the physical free space. Even if you're using FSRM to limit usage, Azure File Sync may continue to tier files based on the logical free space on the volume.

    Please be aware the quotas will also impact sync if the quota is reached.
