I'm using a SQL-Server 2014 database with filestream enabled. To backup this database I'm using the powershell command Backup-SqlDatabase, which is equivalent (as fas as I know) to T-SQL BACKUP DATABASE. The backup is stored in a "mydatabase.bak" file. My question is very simple: is the filestream backed up as well by this command or do I have to take further steps zu back it up?
Backups include both filestream data and relational data. Integrated management is one of the benefits of using filestream/filetable instead of storing files independently.
As suggested by the comments, practice recovery to ensure you can meet your RPO/RTO SLA objectives.
