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

Assuming a nightly 'svnadmin hotcopy' is run w/o errors, is
there 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

Goal of grep and redirects is to only display errors or warnings.

Does a successful 'svnadmin hotcopy' indicate a clean bill of
health for the repository, or might 'svnadmin verify' still
locate problems?
Would like to detect corruption in repository as soon as possible.
