In this scenario， assume that you archive logs 101 to 104 to two archiving destinations， /log1 and /log2. The control file contains archived log records as follows：  
Sequence Filename 
101 /log1/log_1_101.arc 
101 /log2/log_1_101.arc 
102 /log1/log_1_102.arc 
102 /log2/log_1_102.arc 
103 /log1/log_1_103.arc 
103 /log2/log_1_103.arc 
104 /log1/log_1_104.arc 
104 /log2/log_1_104.arc  
You accidentally delete logs 102 and 104 from log 1. You run this command：  
BACKUP ARCHIVELOG FROM SEQUENCE 101 UNTIL SEQUENCE 105；
