First : BackupFiles are *always* files located on server machine so path
'c:\backup\tap.fbk' must exists for remote TAPSERV machine.

Second:

Fix jvuiblib.pas , about line 988 replace
Exception.FErrorCode := GETCode(Status);
with
Exception.FErrorCode := FStatusVector[1];

and you will see proper GDS code number in exception message.

BTW: I cannot set alias name as backup file but I can set alias path.I
don't know if this is correct I thought that alias name is automatically
resolved to path.
