The differential backup is just the addition of the differential option, as you have listed. More details here: http://msdn.microsoft.com/en-us/library/aa225964%28v=SQL.80%29.aspx

However, you need to still do full backups. Based on what you are saying, a few hours data loss, you need to do:

- Full backup once a day
- Differential backup every few hours

If you do this schedule:

00:00 - Full
02:00 - Diff
04:00 - Diff
06:00 Diff
08:00 Diff
10:00 Diff
...

through 22:00 for a diff.

That gives you a two hour data loss window. If you plan on a full backup one day, a diff the next, then you are increasing your risk every day, and could lose up to a day's worth of data.

Hey, I just met the same question. And I don't really want to cost big. So I searched software which can do incremental and deferential backup and restore, as well as some other management features. It seems the feature is quite new. I don't know weather it's safe to use...Does anyone have any idea about it? Thanks!!!!

Generally, such functionality is covered by a third-party tools or your own(ex: PowerShell script). We are using the SQLBackupAndFTP. It has a several restrictions, but in most standart cases it do it's job very well.
