FSA backup with netbackup

Do we have any best practise for FSA backups with NBU

Requirements are as follows

7TB File Server (Actual Data)

3 TB Archived data

i believe windows policy type would only backup placeholders not actual file content

EV FSA partitions requires another policy to be created

in case of data loss how should be recovery procedure. Is below correct

Restore EV FSA first

Restore placeholders from MS-Windows backup

pls share your views

(PS: i guess if placeholders are deleted mistakenly by users, they can still search and retrieve file from search GUI, besides from backup perspective we needed solution)
