This issue has been solved. See solution.

Hi All,

We are in a process of test Disaster Restore and need to know how to calculate the amount of data to be restored.  Is there any command or can it be identified in the GUI.  Likewise, it is possible to know how long will it take for the data to be restored?

The master and the client servers are running in Windows OS and the Netbackup version is 7.1

Thanks in advance for any help.

Regards, Jecintha

Hello Dyneshia,

Thanks for the link and the pdf file.  However, I had already gone through them.  I need to update total size of data that would be restored with the approximate time that would be  required to run the restore.  I am unable to find these details in the link.

Thanks again

unfortunatly there is no direct command to acchive your requirement..

check the below thread..      

You can use bpflist - The command is only available on the master server and is undocumented. But there is a tech note about the usage :

Definition of each field in the bpflist command output

The idea is that you either specify a backup image or a time frame to list the files. Use grep/findstr to find the files/directories in question. The technote above state field 14 is the files size (0 if a directory). You need to count the file size for each file to find a total.

bpflist can be a little tricky to use, but there are some examples here:

you can keep this in some sort script to grep or awk  and calculate the total size.

and you can not exstimate the time,unless you know the general restore speed for your master servers. 

so use bpflist command to get the size of the data on,  and based on your estimated speed(from your past restore jobs) you can calcualte the time.


i have posted an idea on it, if you want you can comment on that..
