Hi:
Overall it seems you want to archive a set of files on a daily basis and then store
them offsite. I assume you want to archive rather than simply backup because you want
to retain each version of the file for a long period of time.
How you would go about it depends on your situation. For example, if you know you want
all archived files from all clients to be retained for five years, then you would have
a single copygroup archive definition defined for the default management class and
the destination going to a specific storage pool to isolate the archives from the
backups. Then you would checkout the newly created volumes in that (archive) storage
pool.
