Hi Sameer,

Thanks for the link. I am going to use foll. commands.

allocate channel for maintenance type disk;
crosscheck backup of database;
crosscheck backup of archivelog all;
delete expired backup;
release channel;
exit

As I understand, delete expired backup will delete catalog records for the backup piece it does not find on the backup location. In our case, we first take the backup on the disk and then on to the tape. After that, we delete backup from the disk. In that case, it will not find backup on the disk and will delete catalog records.

Will it not create problem in case if we need to restore that backup piece?

Pl. make me understand this.

Thanks,
