Hi Dinesh,

As you found, derby does not retain information about the directory
structure around the database, just the internal organization of the
database itself. And the backup/restore doesn't keep that information
Derby processes start from the location where the java process is invoked...
So, to restore to the original position, I'd suggest starting the restore in
the original location.
Or, you can just specify the target directory in the URL, i.e.:
String connectionURL =
That should make mydbname database get restored to c:/temp/one.
