[i]Consider this to be your life's mission.[/i] Bob, I can do without this.
Richard, [i]Actually I use several browsers every day. Each browser has a cache located somewhere in my home directory and the cache is managed so that it won't grow very large. With CDP, I would fill my disk in a week or less, just by caching everything on the internet that I pass by.[/i] if you RTFT, you'd find that nobody ever was interested in temp files. [i]In Uwe's use cases thus far, it seems that he is interested in only the simple single user style applications, if I'm not mistaken, so he's not considering the consequences of what it *really* means to have CDP in the way he wishes. Uwe - am I close here?[/i] Nathan, you are not. Again, there's nothing that I "wanted". I was only thinking. And I am a server person. Now, if I switch from the /export/home/userfoo/Documents (for Richard, who might be happier with UZFS-CDP than with the shots of TimeMachine), to a file server, do the arguments still hold, that 1. The application (NFS - sftp) does not know about the state of writing? 2. Obviously nobody sees anything in having access to all versions of a file stored there? In any case, my presentation at that enterprise-security related conference is done, the 'history' of backups presented (not exactly my topic). I introduced the idea of versioning, and the (possible) advantages of having all versions, including the (possible) disadvantages (storage space, mentioned despite my doubts). I also pointed out the currently available software for near-CDP, and mentioned the discussion we have in here; started for one and only reason (see Subject): to confirm if ZFS can be instructed to produce a copy of each version of a file, initiated by some event instead of a scheduler. Somewhat to my surprise, my presentation was a good success, and Q&A was focused on the event-driven backups, what the technical problems were, etc. A good handful of people approached me later, being curious and fascinated by the idea to replace the backup scheduler with an event-driven creation of the versions. Therefore, to me the case is closed; my presentation done, on the successful side. Thanks to everyone who cared to answer, help, contribute in one way or another, Uwe This message posted from opensolaris.org _______________________________________________ zfs-discuss mailing list zfs-discuss@opensolaris.org http://mail.opensolaris.org/mailman/listinfo/zfs-discuss
