Value in 'svnadmin verify' cron job? (or is ''svnadmin hotcopy' enough)

Question

Assuming a nightly 'svnadmin hotcopy' is run and validated, is there any value in periodically running one or both of?:

svnadmin verify REPO-PATHNAME 2>&1 |egrep -v '^\* Verified revision [0-9]+\.'

svnadmin dump -q --deltas REPO-PATHNAME >/dev/null

(Any output from above is probably abnormal.)

Does a successful 'svnadmin hotcopy' indicate a clean bill of health for the repository, or might 'svnadmin verify' still locate problems?
