    The BOL link provided in previous place is a good place to start.

    Full Backup - Everything in the database will be backed up.

    Incremental Backup - Backup file will contain all pages that are changed after the last full backup.

    Well, there are no incremental backups in SQL Server. Do you mean differential or are you referring to log backups?

    If you are very new to SQL Server and don't understand these, use SSMS to perform a backup or restore of a database. You can right click the database and select the option.

    A full backup is listed. What is an incremental in the file system is typically considered a differential in SQL Server, but a log backup also could qualify. As to what a log backup is, search for "Managing Transaction Logs" and read that article.

    For a restore, you would restore a full backup first, meaning you need one. Then you can restore a differential backup (or a log backup).

    It's a complicated subject, and bears some effort on your part to understand if you need to do this.

    backup types:

    full - backup of all data (backup database ...)

    incremental - backup of changed data since last incremental backup (backup log ...)

    differential - backup of changed data since last full backup (backup database ... with differential)
