ADSM has 2 key storage management items in place today:  backup and
archive.  The backup component of ADSM is meant to provide a very effective
method for performing incremental backups without the need to re-backup
data already managed by the server.

The archive component is meant to keep a point in time copy of an object
(file) for a specified period of time.

Thus to meet your needs (daily incremental plus a monthly full) you should
use the backup component for the incrementals.  Then, once a month
schedule a full archive of each client system.  Set the archive retention
period to 400 days (this would keep about 13 months of backups in the
system).  ADSM allows you to retrieve files that meet a certain pattern
or that were archived between certain dates.  You could thus retrieve any
file archived between 1/1/94 and 1/31/94.

ADSM would automatically remove any archive copies over 400 days old from
the system, thus recycling any tapes, etc., the data may be on.
