Hi,
Thanks for your suggestions. I would be applyin what you just said but i didn't understand your phrase "ok. your backup is only ~4.5G which isnt to bad."
My curren tbackup size is 19.3 G in compressed format and 27.6 G.
Please see the output of the command you mentioned in point 1st, in the attached file.
I have excluded /ml-fixes. And it is taking around 50 minutes to backup.
But my main concern is the size of my backup which is still 19.3 in compressed forat which i can see if i execute the command

# listvgbackup -l -f '/dev/rmt0'

VOLUME GROUP: rootvg
BACKUP DATE/TIME: Mon Feb 16 19:48:00 GMT+08:00 2009
UNAME INFO: AIX sapsvr03 1 6 0000DAE2D900
BACKUP OSLEVEL: 6.1.1.0
MAINTENANCE LEVEL: 6100-01
BACKUP SIZE (MB): 27648
SHRINK SIZE (MB): 19348
VG DATA ONLY: no

Why backup size is this much big?
Thanks

Salman

NAME
ndb_print_backup_file - print NDB backup file contents SYNOPSIS
ndb_print_backup_file file_name DESCRIPTION
ndb_print_backup_file obtains diagnostic information from a cluster backup file. Usage ndb_print_backup_file file_name file_name is the name of a cluster backup file. This can be any of the files (.Data, .ctl, or .log file) found in a cluster backup directory. These files are found in the data node's backup directory under the subdirectory BACKUP-#, where # is the sequence number for the backup. For more information about cluster backup files and their contents, see Section 17.5.3.1, "MySQL Cluster Backup Concepts". Like ndb_print_schema_file and ndb_print_sys_file (and unlike most of the other NDB utilities that are intended to be run on a management server host or to connect to a management server) ndb_print_backup_file must be run on a cluster data node, since it accesses the data node file system directly. Because it does not make use of the management server, this utility can be used when the management server is not running, and even when the cluster has been completely shut down. Additional Options None. COPYRIGHT
