My somewhat old information is that for a MySQL based system one should
restrict access to the application while the backup is made. Faster
machines have reduced the time taken, but if the volume of data was to
increase dramatically so would the time taken to back up? Some of my own
systems can take several minutes to create the backup file which is
still in the gigabytes after backing up but I don't have to stop web
access as the backup will be a snapshot of the data at the time the
process started. I have one with the CDDB data stored locally which
needs 30 minutes for a backup ;)
