Thinking about it, I don't know that you can *move* your backup history
in the way that I off-handedly suggested (e.g. move the backup history
of /home to that of /data/home). Maybe someone else on this list knows
if this is possible.

By default, rdiff-backup will preserve the backup history of /home; it
just won't be linked to /data/home. It will look like the directories
/home/* were deleted and /data/home/* were created as new directories.

You can save some time on the first run of rdiff-backup after the
change by copying /backup/repo/home to /backup/repo/data/home, etc.

One other thought is that you can use bind-mounts instead of symlinks,
if your OS supports it. In this case /home and /usr/local/data are
empty directories in their respective file-systems, /data/home is
mounted on /home, and /data/usr/local/data is mounted on /usr/local/data.
Now your old globbing-filelist will work as expected, history and all.
