Re: Monthly RMAN Long Term Backup

Hi Sallie
Your long term retention backup will contain spfile, control file, and the archivelog needed to make the full backup consistent. The doc says that

You can use BACKUP
<https://docs.oracle.com/cd/B28359_01/backup.111/b28273/rcmsynta007.htm#RCMRF107> ...
KEEP to create a backup that is both all-inclusive and exempt from the backup retention policy
<https://docs.oracle.com/cd/B28359_01/backup.111/b28270/glossary.htm#i432137>. The backup is all-inclusive because every file needed to restore and recover the database is backed up to a single disk or tape location. The KEEP option also specifies that the backup should be exempt from the retention policy either forever or for a specified period of time.

And you can double check with rman list backup command.

Pleae be aware that archival backup can not be used to restore and open resetlogs a db,but can not be used to *duplicate* the database. You can find details, explanation and workaround bere:
