Romain Hardouin commented on CASSANDRA-15301:
---------------------------------------------
There is no bug to fix, a snapshot is just a bunch of hard links.
If you want to backup/restore the new table you need to take another - newer -
snapshot: either a system wide (no keyspace specified) or a specific one
targetting only the new table.
> DDL operation during backup process after made snaphot ,restore will lost
> data
