Yes, all this looks good.

Moving them would be better because they carry the timestamps and
permission information for your home directory.

  DG> mv home/rdiff-backup-data/increments*dir rdiff-backup-data

rdiff-backup-data/increments*dir carry the information for root, so
the above would switch the information from home to root, which
probably isn't what you want.

    Instead, if you want to do everything right (if you skip this step
entirely not too much bad would happen), for each of
home/rdiff-backup-data/increments.T.dir, if
rdiff-backup-data/increments.T.dir doesn't exist, create it by

cp -a rdiff-backup-data/increments.U.dir rdiff-backup-data/increments.T.dir

where U is the closest time to T (and thus has about the right
timestamps and permissions).
