I have to live with MSSQL at work, and I didn't remember anything like
this, so I looked up the syntax for CREATE INDEX
(http://msdn.microsoft.com/library/default.asp?url=/library/en-us/tsqlre
f/ts_tsqlcon_6lyk.asp), and I can't find anything that gives the user
control over this. The closest is this note in the remarks:
Backup and CREATE INDEX operations do not block each other. If a
backup is in progress, index is created in a fully logged mode, which
may require extra log space.
It sounds to me like they fall back to 'online' index creation if a
backup is in progress, but give the user no control over it. I also
looked in the settings and didn't see anything relevant.
