rdiff-backup stores service data in only one top-level backup
subdirectory, in your case in /backup/DataFull/rdiff-backup
There is no rdiff-backup subdirectory in /backup/DataFull/test1, so I
suppose it thinks that backup was never made there.

Mat be to use rsync with "dry run" option to compare?
Like rsync -n -av --delete /data/test1/ /backup/DataFull/test1
(check rsync man for complete set of options, but don't forget -n :)
