I am testing veritas for Windows and Linux system. It did a great job for our Windows back. My question here is will the iso file works for Linux system as well. Or do I have to download different iso for Linux system.
I have moved your post to the Backup Exec forum.
When you mount the ISO on a Windows machine, you will see the Unix or Linux folder in the root folder.
Follow BE documentation https://www.veritas.com/support/fr_FR/article.100017476
to extract and install the software on the Linux server.
Hopefully you have checked the BE SCL for compatibility?
