The 2GB file size limitation is actually a kernel issue.  The 2.2 kernel
does not allow any single file in the filesystem to be more than 2GB in
size.

You need to find a way to make your backup files smaller than 2GB - rather
than just doing one single backup for your entire machine, do many smaller
backups for each user, etc.  If a single user has over 2GB of files, you'll
need to roll your own tar/FTP script to do the backups instead of relying
on the solutions in the UI, as we don't offer a very fine-grained option
(per-file selection, etc).

The backup should start running at about 4am (that's when most of the
system jobs happen).  It is probably taking a couple of hours to run your
backup job, especially if your machine is "in use" (web traffic, etc)
during the backup cycle and you're backing up 2GB of files.

There's no way to change the time if that's how long it takes to back up
your content.

You might want to look at doing a smaller backup each day during the week,
and then do a "full" backup once a week or something.
