@Rose, Sylvain Welcome to Microsoft Q&A platform, Thank you for posting your query here!
Firstly, apologies for the delay in responding here and any inconvenience this issue may have caused. Adding more information @shiva patpi .
Additional information: You need to install the agent in another on-prem Server and configure the Azure file sync.
For example, you have two distinct sets of files that you want to manage with Azure File Sync, you would create two sync groups and add different endpoints to each sync group.
When adding a new server endpoint to an existing sync group, if you choose either the recall namespace first option or recall namespace only option for initial download mode, files will show up as tiered until they're downloaded locally. To avoid this, select the avoid tiered files option for initial download mode. To manually recall files, use the Invoke-StorageSyncFileRecall cmdlet.
If cloud tiering was enabled on the server endpoint and then disabled, files will remain tiered until they're accessed.
Hope this helps!
Kindly let us know if the above helps or you need further assistance on this issue.
