yes;
However you Do want to to respect the guidelines / constraints in 
regards to the recovery-log;
Simle Description: Continuent logs each UPDATE statement in seperate 
Databases (RECOVERY) on the Controllers in order to "document" all 
DB-changes since the last full dump, so it my re-play the changes since 
then.
The configuration-task is to define the MAX-size an UPDATE Statement 
might reach;
The "larger" UPDATE-Statements we experienced are:
- huge RTE Text stuff and
- the uc_ field in be_user;
However in your particular TYPO3-Setup, there mght be other/larger 
UPDATE-Statements.

hth regards georg
PS: The Continuent-Support IS excellent;
