Feature Request
Is your feature request related to a problem? Please describe:
Currently, when trying to br restore a table after run query "delete from t1;" and "truncate table t1;" is different:
CREATE TABLE `t1` (`a` int(11) NOT NULL, PRIMARY KEY (`a`));
insert into t1 values (1), (2);
br backup t1;
delete from t1;
restore t1 => BR:Restore:ErrRestoreChecksumMismatch
CREATE TABLE `t1` (`a` int(11) NOT NULL, PRIMARY KEY (`a`));
insert into t1 values (1), (2);
br backup t1;
truncate table t1;
restore t1 => Success
Describe the feature you'd like:
After execute query "delete from t1;" or "truncate table t1; br restore should not allow user to restore to the table t1, as table structure still exists in this cases.
Describe alternatives you've considered:
