What are the differences between
Differential vs LOG bAckup
Bulk recovery vs simple Recovery
Google is your best friend. But here goes anyway:
Differential backup
- A file which contains ONLY the changes that have occurred since the LAST full backup.
T-Log backup
- A file which contains transaction logs?! (basically the instructions SQL server used to make changes to the database)
Simple Recovery
- Doesn't allow Log backups. SQL Server automatically reclaims log space so no management from the user is required.
Bulk recovery
- Bulk operations are minimally logged - other operations are logged as normal.

Bulk recovery
- Bulk operations are minimally logged - other operations are logged as normal.
But that's true for simple recovery as well.

I didn't know that. My understanding is that SIMPLE is the same as FULL except that SQL Server reclaims log space by itself and you can't do T-Log backups so no point in time recovery.

Nope. Maybe read the last two articles I linked above.
