RMAN doesn't care whether the backup is cold or hot. There is no difference. In fact, to do a cold backup, you have to mount the database in RMAN, so it really isn't COLD. It is luke warm.

But does this not imply that the level 0 back and incremental backup have to be the same? All cold backups or all hot or on-line backups?

Yes, does it automatically, no action on your side needed. Basically a restore of a datafile or the database will restore the last cold backup. The recover command will then apply incremental backups as possible and then archive redo to complete the action.

Does this make sense:

Incremental backups for database every day (based on block change tracking approach - new in 10G). Archivelogs are backed up everyday. Full cold backup on the weekend. Recovery using previous cold backup and applying incremental backups & archivelogs.

I am reading this in a doc given to me.

Can you apply an incremental backup ( level 1 or 2 ) taken during the week to a cold backup taken on Sunday?

Can the BCT feature be used with a cold backup?
