Can I do a incremental restore for all databases in MySQL?

I am executing the following steps in MySQL 4.1.18

I have 4 databases (d1, d2, d3, d4). I have taken a full backup, then modify some tables in databases d1, d2, d3, d4. Then took a incremental backup for all databases. Then took a full restore (for full backup). Then I want to take a incremental restore for all databases.

After doing incremental restore, I got error saying duplicate tables..

So I just want to clarify whether it is possible to take all the databases for incremental restore?

Thanks in advance,
