Will Database backups use instant file initialization

Instant file initialization as the name suggests,it helps in instantiating file opearations instantly,so will it help in database backup process too.

Short answer is no.

when you first create a data file  or increase size of it or restore it,it has OS will first fill out the space with Zeroes and then SQL can use it.With IFI enabled,this process is skipped.So below are the only operations used by IFI as per MSDN

create database

restore database

increase file

Further IFI wont have any effect on log files ,since during crash recovery,SQl will try to read garbage data instead of Zeroes.More on thsi here from Paul  .One more reason why not to shrink log unless needed
