Yes, a SAS solution for that would be possible, but why do you not create a
subdirectory with the date and copy all the files into that? I think the
handling is much more easy! You only have to change the libname in SAS and
you can access all the backuped data very easy! That could be also managed
in SAS very easy! You just create the subdir with a call system("mkdir
subdir-name")
or
call system("mkdir &macro_var");
then allocate it with

libname backup "&macro_var";

and add a

proc copy in=... out=backup;
run;
