Correct on all counts. Using a tool like Bacula (open source, but support available and z/OS friendly) or TSM (from IBM) provides the file level backup and recoverability required in this environment.

So, if I'm understanding this correctly, taking a backup of a running Linux system from another LPAR gives you, at best, an unreliable backup. That means that there are only two viable alternatives: Shut down Linux and do the backup from another LPAR or, Use a backup client that runs within Linux and therefore participates in its file system processing, getting all the current and correct data for the backup. Is that about it? The problem, as I see it, with backing up from another LPAR is that there is no incremental or differential backup capability. Nor is there any selective restore capability. Its an all-or-nothing backup/restore. Paul Noble Cuyahoga County Information Service Center
