What does a database restore do?

A complete database restore involves restoring a full database backup and, optionally, a differential backup (if any), followed by restoring all subsequent log backups (in sequence). The complete database restore is finished by recovering the last log backup and also restoring it (RESTORE WITH RECOVERY).

What happens when you restore a whole database?

Restore Database Consistent A consistent restore brings all datafiles in the database to a consistent state (all files are restored as of a single point-in-time), where no recovery is needed to open the database. This can only be accomplished if all the files come from a single backup offline database.

What is difference between restoring and recovery of database?

Restoring involves copying backup files from a secondary storage (backup media) to disk. This can be done to replace damaged files or to copy/move a database to a new location. Recovery is the process of applying redo logs to the database to roll it forward.

What is difference between restore and backup?
