Total backup and Psadump question

[Mr.Yes]

Hello,

i have a licence for 4psa's Total backup but never used yet, i did just some experiment on a local server.

Now i asked to 4psa what command they use to perform a backup with psadum through Total Backup interface and they wrote me the following:

# psadump -F -f - --tar-ignore-failed-read --noblock --nostop-domain --nostop --no-internal-zip --force | %s --output='s'


Now my question for you is: somebody of you know what --noblock or --no-internal-zip commands means?

Do you think it's a good idea to use that string with my personal script too to perform a psadump backup ??

thanx
