How dump database cumulative works?

Hi,

I have some doubts about how the dump database cumulative command works,

I guess that the changes perfomed after a dump database full are registered ( not in the syslogs table) and when you send a dump database cumulative ase backup those changes.

I want to know if I can use this command in a database that has the options "trunc log on chkpt" and "select into/bulkcopy/pllsort" set?
