I am looking into setting up a backup scheme. Currently I want to backup to
disk, than from disk I will backup to tape.

From what I have been reading it seems that BACKUP INCREMENTAL LEVEL 1 DATABASE will take faster to do the backup and slower to restore as opposed to a BACKUP INCREMENTAL LEVEL 1 CUMULATIVE DATABASE, which
will take longer to backup and faster to restore. Do I have that correct.

In addition, If I do my level 0 backup on a Sunday and M-F do my LEVEL 1 it sounds like I need to keep my recovery window to at least 7 days, is that correct?

Lastly, how do I recover can I recover from my DB. Can I do something like
this (see below) and this will bring me back to the most current transaction?


run {
allocate channel d1 type disk;
restore database;
recover database;
alter database open;
}

The last person was just doing full backups everyday and it was
eating up way too much disk, space so I am looking to cut down on the disk usuage.

Pardon my nievte, since I am not an offiicial DBA and have been gathering
all my informaiton from google.

Thanks in advance to all who answer this post.
