Hi

I have a policy where it includes stream variable.  The following information gives clear picutre.

policy name : MS-SQL-DB

include files:-

Newstream  ( 1st Part)

e:\ *.bak
f::\*bak
g:
h:
j:
K;
 New Stream ( 2nd Part)

L:
M:
N:

Q:
New stream ( 3rd part)

when ran this backup manually it initiate 4 process with job-id 37471, 37472, 37473 and 37474.  If we notice the details column in job-id 37471 it includes all the above mentioned files and says the total size of the backup is approximately equall to 1.09TB. If we notice the same way for job-id 37472 it says, it accounts first part of backup selection and equalls to 1.09TB, the job-id 37473 accounts 2nd part of the stream and size is equall to 1.25TB and job-id 37474 is equall to 0.81TB, accounts for 3rd stream only.

Also noticed that for job-id's 37472, 37473 and 37474, the parent job is 37471.  Also noticed if all later jobs are completed the parent job also closes in successful condition.

Well i need to understand the following.

1.  What is the total size of the backup.  Because it varies.
2. Do i have to take the amount which is equall to parent job ( Which includes all the includes files) or individual job-ids?
3.  The amount of backup space is varying compared to parent jobid and sum of the individual child job-ids.. 

Based on your inputs i need to reserve some of the tapes during weekend jobs. 

Appreciate your comments.

The environment is NBU 6.5 runs on solaris with linux, solaris and windows as clients.
