I'm not trained in AS400.
We don't use tapes anymore but backup to a remote Data Domain.
AS400's audit journal receiver of our developmt AS400 is taking too much space in our current weekly backups with retention of 6 years.
a) Without compromising on the 6 years' retention, how can we reduce the space taken by the backups in the Data Domain?
b) I suppose weekly backup is taken because the receiver journal is rotated weekly: is there such thing as incremental or
differential backup in AS400 for audit journals?
c) can we do it monthly with differential backups or what other strategy can we do it?
d) can it be compressed? the Data Domain solution we used is from EMC. Anything on deduplication??
We are on OS400 V7 R2 running DB2
