Thanks for the patch, Kim. This makes the online backup documentation much clearer.

The html files look good to me. +1 to commit.

> The Admin Guide does not mention that the online backup functionality is non-blocking.
The information that a backup can be made without blocking transactions may be of great interest
to administrators.
> Furthermore, this sentence implies that online backup is performed by *blocking* updates:
> "The SYSCS_UTIL.SYSCS_BACKUP_DATABASE() procedure puts the database into a state in which
it can be safely copied, then copies the entire original database directory (including data
files, online transaction log files, and jar files) to the specified backup directory.
