We have large search service application with 10 Million items in the index running on two sharepoint server and index is growing on daily basis.
We we planning to take the backup of search service application, it is expecting 220 GB free space needed. We don't have sufficient space on search servers as index data is consuming disk space.
Can we choose database server (where the search databases are hosted) as the backup folder location and take the search application back up?
Can we restore the backup from database server if required in the future.
What are the permissions needed for the backup folder apart from farm account and search service account?
