Cbbackupmgr Incremental backups

I was wondering if cbbackupmgr includes an option to tell it to do a incremental or differential backup like cbbackup does. If so how would i tell the manager to back up only increments or differentials ?

cbbackupmgr backup -a /media/backup/crm -r single -c couchbase:// -u Administrator -p Password

when i use the above the mode or m is invalid and i cant find anything in the docs to cange the type

cbbackupmgr backup command, by default, does an incremental backup (if there is no previous backup, then, it’s a full backup) – here’s the doc info

There is an option to do a full back (--full-backup), but it’s not documented in 6.6 – it’s documented in 7.0 Beta doc.
