NMM SQL server filestream backup

Dear Experts!

Our customer want to backup SQL server with NW8.2.3 and NMM8.2.3.

However we got the following error during the backup:

>SQL Server FILESTREAM support is not enabled for this instance.

>Database db1 using FILESTREAM functionality cannot be backed up.

Question:

- How can we set up with NMM backup?

- It is possible with NMM?

- It is the problem on the SQL server side or NMM side?

Thanks in advance.
