The information about backups is not yet included in the 
official MySQL manual.

You can read about it in the "MySQL Cluster Administration 
Guide" guide, which you can find on:

Note, however, that this MySQL Cluster Administration Guide 
is not being updated anymore and that many things in it are 
not up to date. 

We are working on including all information in the 
MySQL manual.

mysqldump/mysqlhotcopy will probably not change behavior
in the future.  NDB backup might.

Started the backup.  See cluster log for when it is finished.

See Admin guide.

Only the "unofficial" Admin Guide, but hope it gives you some hints.
