see http://qmail.jms1.net/backup.shtml ... explained in full. > I suppose I should overwrite > /home/vpopmail and /var/qmail fully with my backed up version? no. the web page explains exactly what needs to be backed up and restored. the backup scripts i run on my own server and my clients' servers use this list, and i've actually done several recoveries (from dead hard drives and dead servers) where nothing was lost except new mail which arrived after the most recent backup. > but this > couldn't cause later problems with courier-imap compiled binaries? because > they're compiled with just have installed vpopmail libraries and not with > backed ones? when courier-imap (or more specifically, courier-authlib) is compiled, it is STATICALLY linked with libvpopmail.a. this means that the "libvpopmail.a" file needs to be in place while courier-authlib is being compiled, but it doesn't need to be there (or it doesn't need to be the exact same version) when it's running. one of the design goals of vpopmail 6 is to have a dynamic library. when this happens, and if courier-authlib is changed so it uses the dynamic library, the libvpopmail.so file will need to be in place for courier-authlib's "authdaemond" process to run. however, minor updates to the libvpopmail.so file (re-compiles, minor upgrades to fix bugs, etc... things which don't change the API) will still allow authdaemond (and other programs which dynamically link against the library) to work correctly. the whole point of dynamic libraries is that the functions in the library are found by name at run-time, rather than having an explicit address or "function number" be hard-coded into the executable. -- ---------------------------------------------------------------- | John M.
