The <code class="function">db_copy()</code> routine copies the named
|
||
database file to the target directory. An optional password can be
|
||
specified for encrypted database files. This routine can be used
|
||
on operating systems that do not support atomic file system reads
|
||
to create a hot backup of a database file. If the specified
|
||
database file is for a QUEUE database with extents, all extent
|
||
files for that database will be copied as well.
