Problem with Database restore

Dear All,

My database backup INCREMENTAL LEVEL 1 script looks like as follows.

RUN

{

...

backup INCREMENTAL LEVEL=1 DATABASE format '\\backstorage01\LVL1_db_bk_%s_%d_%T.bck' TAG=DB_LEVEL1_BAK include current controlfile plus archivelog format '\\backstorage01\LVL1_arc_bk_%s_%d_%T.bck' TAG=ARCH_LEVEL1_BAK;

delete noprompt archivelog all backed up 1 times to DISK;

}

Everything goes fine and the output of my backup script log file looks like as follows.

...

channel c3: starting incremental level 1 datafile backup set

channel c3: specifying datafile(s) in backup set including current SPFILE in backup set channel c3: starting piece 1 at 09-JAN-17
