If I have the following:
--Weekly full backup--
backup incremental level 0 database plus archivelog delete all input;
-- Daily backup --
backup incremental level 1 database plus archvielog delete all input;

By having the above backups all the archivelogs after the backup will be deleted.
What about when I will need to do a restore, don't I need the archivelogs as well and how to do a restore is RMAN>restore database; is ok?
