Before the table being physically deleted, you can recall it alive and restore its data.
This command requires the table ID to restore, which you can see via "ls --drop" command.
By default, recall will create a new table with the same name as before.
You can specify a new table name as the second argument.

Sample:
  recall 16 new_table
