If those servers are in the same network, you can:
a) insert data into damaged table
INSERT INTO original_table
SELECT * FROM backup_table@another_server;
b) drop damaged table and create a new one
DROP original_table;
CREATE original_table AS
SELECT * FROM backup_table@another_server;
Otherwise, create an export file of this table on backup server and import it into the original table:
ANOTHER_SERVER> EXP username/password@database TABLES=backup_table FILE=backup.dmp
THIS_SERVER_SQLPLUS> TRUNCATE TABLE original_table;
THIS_SERVER> IMP username/password@database FILE=backup.dmp IGNORE=Y
