Using WildCard - Backup Selection

You will need access to the Windows File server to double-check the path.
H:\Profiles\a* should at least work.

If correct, the problem could be with the NBU Client Service logon account.
The default is LocalSystem and may not have access to the User folders on the Fileserver.

Change NBU Client Service logon account to a domain account with read and write access (read access for backups, write access for writing logs and restores). Restart the service and retry the backup.

I m using only H:\Profiles\ now...and it is backing up successfully.

But i want to stream the job and take it faster as the data is around 1.8 TB.

Hello Marianne,

I had checked the path and it is like H:\Profiles\Last_Name.First_Name of the users.

H:\Profiles\a*...according to me should backup all the users whose domain name starts with "a" in profiles folder.

Have you checked Client Service as well on File server?

If the logon account does not have access to user folders the backups will fail with status 71.

*** EDIT *** 

Looking again at your post above:

I m using only H:\Profiles\ now...and it is backing up successfully.

Are there actually users starting with 'a'?

Once backups have completed for H:\Profiles, you can verify user names with bplist:

bplist -C <Fileserver> -t <12> -s <start-date> -R 3 /
You may want to send output to file if there is lots of output.
 

This will list the top 3 levels of paths and will give you good idea of what needs to go into Backup Selection.

We have seen good throughput with about 4 streams and Backup Selection split into something like this:

NEW_STREAM
H:\Profiles\a*
H:\Profiles\b*
H:\Profiles\c*
.....
H:\Profiles\g*
NEW_STREAM
H:\Profiles\h*
H:\Profiles\i*
...
...
NEW_STREAM
H:\Profiles\x*
....
