Well, Kern pointed out that this was an example, and I suppose by that he means that you have to modify it to your specific needs. Kern is more busy coding than doing user support, so I think it's expected that he doesn't answer in great detail... > However, your setup makes sense to me and > seems less fragile, so I think I'll go with it.

Usually, you can exclude quite a lot of the files in there - there are many temorary files in there, like browser cache etc. > This would mean that with a > max volume size of 2GB, the single job would be split over 3 volumes. > I seem to remember discussion in a recent thread that bacula can > handle this, but how nicely does the database deal with it (I'm using > MySQL).

That depends - 2 GB is a good limit if you want to be able to copy volume files to out-of-the-box external disks, 4.something is good for DVDs, 700 or so MB for CD - whatever you plan. I would limit the file size to something below 10GB in any case. > On a personal note, I'd like to thank you for one of the best > responses I've seen in the weeks I've been following this list.

Not everyone finds the time for detailed answers for all the questions, though, but that is expected as we're all doing this in our (limited) spare time... and regarding politeness - this is one of the most polite mailing lists I know. I guess we'll have to thank all the users for that! > ~Kyle Marsh > Arno -- Arno Lehmann IT-Service Lehmann www.its-lehmann.de ------------------------------------------------------------------------- This SF.net email is sponsored by DB2 Express Download DB2 Express C - the FREE version of DB2 express and take control of your XML.
