Uh. If backuping up a live database from a snapshot is not
trustworthy, either the snapshot facility is broken or the database is
broken (i.e., not crash-safe to begin with).

That said there are plenty of other reasos to use proper dump tools
(data portability, confirming the ability to actually read all rows
from a table, using a more often exercised code path and perhaps less
likely to have edge case bugs, etc).
