Actually Miles, what they were asking for is generally referred to as a
checkpoint and they are used by all major databases for backing up
files. Performing a checkpoint will perform such tasks as making sure
that all transactions recorded in the log but not yet written to the
database are written out and that the system is not in the middle of a
write when you grab the data. Dragging the discussion of database
recovery into the discussion seems to me to only be increasing the FUD
factor.
