That's certainly how I read it. > > That means that there are only two viable alternatives: > > Shut down Linux and do the backup from another LPAR or, Yes. The plus is that you can then restore your Linux environment the same way that you restore the z/OS or z/VM environment. Also, you can manage your tapes using your standard tape management software (which doesn't exist at all on Linux, as I understand it). The minus is unavailability of the Linux system during this time (which is shorted by some sort of "snap shot", if you have that capability) and well as it being an "all or nothing" DASD level backup / restore, which is not useful for restoring individual files. > > 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. Correct. But, again, Linux does not interface to the "normal" tape management systems used by other System z operating systems. > > 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.
