The way incremental backups are handled in NDMP is via a
setting called “Dump Level” this can be a number between 0 and 9, 0
is the full backup of the system and each level after that (1-9) backs up all
the changes the filer tracks since the last dump level.
What you want to check is that the policy you have this
filer in has a weekly (or at least once every 10 days) full backup and the
other backups either cumulative or differential incremental backups.
If you do a cumulative incremental backup the dump level for
all incremental backups will be 1 (meaning all the changes since the last
full). This will use more tape but will assure a faster recovery. If you have a
differential incremental you will see dump level from 1 to 9 or in most cases
from 1 to 4 (Monday through Thursday).
What you will want to do is look in the NDMP log for an
incremental backup to see what the Dump Level is set to.
You do not happen to have any scripts that are cleaning up
the streams files from in the NetBackup\db\images directory do you?
