Having just done this migration for everything except inboxes. Mbox format is _very_ susceptable to complete loss. I've just had to do a series of mbox restores for a user who decided the way to deal with a sync problem was to delete the files, then realised what he'd done That's apart from the backup hassles. - 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.

Re: [Bacula-users] large files / diff backup
but I believe the incremental and differential backup mode is related only to whole files, not to their content - is there such feature or is there some other way to handle such scenario? Yes, Incremental and Differential mode both work on whole files not their diffs. At this time there is no such feature and I do not believe this is on the projects list.

The only thing I'm not sure about is whether Bacula is able to backup huge files (say 2GiB) that change quite often (several times a day) but only a small fraction of them change (most of the file does not change). This is the case with mailboxes for example - the inbox / sent files change quite often, but only a small fraction of them really changes.

I guess the rsync et al. would handle the large files in the same way as Bacula, but most of the machines are running Windows, so this is not an option anyway.
