Description:
The backup files are not removed when doing 
ndb_mgm -e "ABORT BACKUP backup_id"
during backup.

There is the message when aborting backup 2:
2009-03-26 13:32:00 [MgmSrvr] INFO     -- Node 1: Backup 2 started from node 3
2009-03-26 13:32:01 [MgmSrvr] ALERT    -- Node 1: Backup 2 started from 3 has been aborted. Error: 1321

So, backup 2 has been aborted. Also, all the files for backup 2 should be removed as well. But actually, the files are still there, and when we want to backup again  using the aborted backup_id, then problem happens.

How to repeat:
1. Start a cluster with one ndb_mgmd and two ndbd
2. ndb_mgm -e "START BACKUP SNAPSHOTSTART WAIT STARTED"
3. Verify backup id
4. ndb_mgm -e "ABORT BACKUP backup_id" 
Note: step 4 should be done during backup but not until backup has finished

Suggestion:
Should look for complete marker before it decides to overwrite
