Incremental need a full backup to work, is a synthetic ok?

Hi, in the doc it say:

Backup Exec adds the time of the backup to the Backup Exec Database only if the full backup job completes successfully. If it does not complete successfully, subsequent differential or incremental backup jobs back up all of the data instead of only the data that changed.

Does a synthetic backup that complete successfully will make the next incremental backup work, or it really need a full backup?

thank you,

You must run the Full backup for the incremental or differential backup to be successful as they are dependant on the Full. 


Let me Clarify my above statement... 

 You can run your incremental backups off of a synthetic backup but you must periodically run a base/full backup to ensure that there is not corruption.
