I'm responding only to the mainframe issue: -TSM does not understand mainframe legacy filesystems (the legacy filesystems contain the vast majority of mainframe files in most sites).
-Mainframe backup software does not understand UNIX or Windows filesystems. So to backup mainframe legacy filesystems, you need mainframe backup software. However, it gets really confused because: a)You can run a TSM server on the mainframe, to back up your Windows and Unix servers.. b) There is a component of z/OS called OSS, or Open System Services (actually I don't know what it's called these days, the name keeps changing) , which uses a unix-style filesystem. To back up individual files for that filesystem ONLY, there is a TSM client. So you can use your Windows or Unix or mainframe TSM server to backup the mainframe unix-style filesystem. But not mainframe legacy filesystems. c) Also, it's not uncommon to have the mainframe backup software sharing the same tape library with open-systems TSM. But they aren't sharing backup duties.
