Hi,
One of our user accidentally overwrote the original dataset. Could anyone please tell me how to recover previous version of the dataset?
I appreciate the help.
Regards,

If you do not have a backup (after checking with your IT staff) then how was the data set created initially? If it was read from another data source did you keep that program and source file? If so, rerun that code (and any cleaning/modification step up do but not the code which destroyed.
Now, go back through all of your code and change all the instances of
Data olddataset;
set olddataset;
to something like
Data newerdataset;
set olddataset;
to prevent this.
And beat all the programmers/users that use that old/old syntax with wet spaghetti noodles until they promise to stop.
It might not hurt to bill the time/effort cost to the offending persons project budget as a lesson if possible.
