I don't quite understand the wording of your question, but maybe my explanation
will help.
A cumulative incremental in NetBackup will take a copy of any file that was
created or modified since the last full backup. That TIR adds is knowledge of
what files were deleted in that same time frame. Or to say it in a different
way, what files are on the full backup that are no longer on the file system at
the point the cumulative incremental was run.
When a restore of an incremental is executed with TIR in play, deleted files
are not restored. Hence it is a 'truer' picture of exactly how the file system
looked on a particular incremental backup.
I suspect you have something like this going on:
Full backup: 1000 files backed up.
Time passes, 200 of those are deleted, 200 different files are created.
Cumulative Inc: 200 files backed up.
You restore with a time period that includes the cumulative and without TIR,
and you get 1200 files, and possibly a disk full. You restore the same with
TIR, and you get 1000 files.

Subject: [Veritas-bu] Restores from Cumulative incremental backups
Hi,
I'm a bit confused now about Cumulative incremental backups - If data is
restored from last cumulative incremental backup, files that have been created
between last full and the incremental backup are not deleted by NetBackup,
which resulted in my restore failing because it run out of space on that drive-
there were too many new files created after last the incremental.
All I need is a reliable method of returning the partition to exact state as it
was when last incremental backup was taken - I was hoping True Image Backup
would do that, but it seems to have the same behaviour in regards to the files
created between full and incremental backups.
Any suggestions on this?
Thanks
