Check Alert.log file to see when was the last archive generated.
Incomplete recovery is the option
1. Note the current log sequence number
SQL> select * from V$LOG;
2. Restore all the datafile from previous backup
3. Recover the database until cancel to stop before the lost redo log is applied
SQL> recover database until cancel;
4. Open the database using RESETLOGS
SQL> alter database open resetlogs;
5. Recreate the missing logfiles. If logfiles need to be recreated on another disk
SQL> alter database drop log group
SQL> alter database add log group
6. Since incomplete recovery is performed, the database should now be backed up
