    In Netbackup copy numbers are sequential, each new copy get is own copy number that is retained during is's lifetime. Expiring a copy does not "re-arrange" the copy numbers. Restore is always carried out from copy number 1 also know as the Primary copy. You can change the primary copy with the bpimage command.

    As you have observed changes in the copy schema will result in different copy numbers. Using Netbackup Storage Lifecycle Polices is designed to handle multiple duplication and will secure each duplication is completed before the next start.

    Hope this answers most of the questions.
