change image retention from 28 days to 7 years on backed up image
I have backed up a large file server which takes 5 days to backup using the Storage Lifecycle policy with weekly retention where it backups to VTL and then copied off to the tape for offsite. As such...
You can use bpexpdate to change the retention of backups already duplicated to tape.
You can change the retention level in the SLP for the duplicate copy going to tape STU. Leave the backup to VTL with 28 day retention.
That is the whole idea with Storage Life Cycle Policies - to accommodate different retention needs on different storage types.
I assume that you have customized a retention level for 7 years using Host Properties?
