Historically, problems with NAS came from mismatches between the interface programs expect with a local file system and the protocol used to provide remote access.
Reading the development documents for NFS from version 2 onwards, particularly the discussion on idempotent transactions, stateless servers and locking, is instructive.
I haven't looked at this more recently so don't know whether there is now a standard solution to these problems.

Check out rsync. It is a very intelligent program with all sorts of connectivity options, and can keep mounted filesystems backed up.

If it was good enough for my great[sup]n[/sup]-grandfather then it should be good enough for me.[/QUOTE]Don't knock it. It is by far the longest lived information storage technology yet fielded. Surviving petroglyphs long predate papyrus and clay tablets. The latter are much more robust than the former.

I've seen very serious proposals that inscriptions on Pt (by preference, because of its hardness) or Au (it's cheaper but softer and more attractive so more likely to be reused) be used to store information which we would like to last for millennia.

But the available storage is tiny. And the write times are very long.

Yes. I am loving rsync. It only backs up again the files that have changed (based on size and timestamp unless otherwise stated). And it deletes files from the backup set that have been deleted on the master. :smile:
