i have configured daily script to take backup of database to disk.then another daily script does the disk to tape copy of all the backupsets.

to reduce the "disk to tape" redundancy , i changed the disk to tape script to "backup backupset all not backed up 2 times;"

now the script does skip the backupsets which are already backed up 2 times.

skipping backup set key 6283; already backed up 4 time(s)
skipping backup set key 6285; already backed up 4 time(s)


however when i did
list backupset 6283

i get error
RMAN-20215: backup set not found
RMAN-06159: error while looking up backup set


in o/p of list backup summary - i noticed that the value under "key" column in list backup summary changes.
i understand this is unique key identifying backupset.
then how does it change?does "backup backupset" cause this to change?
