Company data missed in SAP IDES system

Hi friends,

In our SAP IDES ECC 6.0 EHP 5 system some data had missed(some plants had missed) in 800 client, I checked 000 client here also no data..we don't have any backup. If I download the IDES from market place, then is it possible to get entire data of 000 & 800 clients. Could you please any one help me how to get our data back..

Thanks in Advance
