a backup may also need to be available from a specific date for compliance or
record keeping reasons

This is a bad policy. A backup is supposed to allow recovery to a point in
time with zero data loss. These monthly backups will never be used like
backups are meant to be used. They could be dangerous to your database if
someone restores them without knowing what they are doing. If there is a
justified reason to store snapshots you should just do an export and keep
that however long is needed.

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 ... KEEP to create a backup that is both all-inclusive
and exempt from the backup retention policy. 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:

Hi –
I currently have a daily full RMAN backup job that runs each evening and
one additional job that runs every 2 hours to backup the archive logs. My
setup is that the full backup is kept for a recovery window of 14 days and
for the archive log files, once they have been backed up twice they are
deleted.
I have a new requirement for a new job to be run monthly to get a full
backup of the database and keep that backup for a year. I’ve been
researching this and found that to do this I can use the ‘keep until time
sysdate +365’ to accomplish this. My understanding is that by using the
‘keep until’ parameter RMAN will backup the database as well as any archive
logs needed for a consistent backup. And spfile/control file as well?
I’m trying to understand how the archive logs backups work in this
situation. When the monthly backup is run and needed archive logs are
included in the backup is that counted against the 2 that I normally want
to keep? And also could there be a situation where a needed archive log
might have already been backed up twice and therefore been deleted? These
monthly backups are going to be written to DDBoost at our DR site and so
I’m wanting to be double sure that I know everything needed for a restore
is included – but also that I haven’t done anything that would upset my
normal backup routine.
Any insight would be helpful – Thanks!
