Hi ,
Ok, but if td is not keeping the info , you mean keeping the info of stats before restoring and apply them after ,on this case yes . Generally,
on my opinion you must keep a metadata table which keeps all the collection of stats, number of rows, in order to be able to check if 10% change
is accurate , in order to take correct decision about the frequency of collection.
