I don't think that's true.  A snapshot can be initiated at any time,
regardless of backups.

A snapshot showing "busy" merely means there is some process using it,
in your case a dump but could be snapmirror or ndmpcopy as well.  The
.snapshot volume decreasing in size is usually indicative of previously
deleted data being rolled off of a snapshot.
