I started with RAID and came to the same conclusion with the hassles, then I switched to rsync. However, I just do rsync about two or three times a week. With your setup, it will probably be a wash - meaning, every time you run rsync, it has to check the whole tree EVERY TIME to see what has been updated, deleted, added, etc. which takes time for the primary drive (at least from my understanding of what is going on behind the scenes). So to run rsync every 15 minutes or so, is going to bog down the primary drive. Also, with rsync (at least with my limited knowledge of the options), if you rename a file - it deleted the old one and copies the new one - instead of remembering you only did a rename. At least from my humble opinion, you should stick with RAID.
thank you for your toughts. i think you're right that the cost of unconditionally rsync-ing the whole drive every 15 min would be too high. but thinking through the setup i'm planning, that wouldn't be necessary. it's (almost) computer illiterate library staff who are scanning & photographing old books and manuscripts, saving the resulting image files. i won't let them put things into the final archives, but they'll save everything into their HOMEs, from where i'll pick up the images remotely, rename them according to some standard still to be made up (date, time, location in the filename), and move them into the actual archive. means i'd have to rsync the HOMEs frequently during work hours, with not too many changes, and once the archive when i'm done renaming & moving everything at night. to me this doesn't sound like too much strain from rsync, but i'll have to get deeper into rsync and it's various options. i'm afraid i'm overlooking something obvious, that's why i'm asking here, where many have much more experience with this type of thing. -- phani. -- To unsubscribe, e-mail: opensuse+unsubscribe@opensuse.org To contact the owner, e-mail: opensuse+owner@opensuse.org
