The dump file may be fine (I still too new to FreeBSD to say for certain), but
you may wish to make another just to be safe. The dumpdates file is used to
record when a dump was made and which level was used for the dump, and so is
really only important if you want to make incremental backups. You can either
specify a different, modifiable dumpdates file with the '-D' flag if you want to
perform incremental backups, or just make full backups each time by excluding
the '-u' flag and a level specification when making the dump.
