Deduplication Best Practices Question

When looking at the Best Practices for DeDupe in R3 I came across a line that reads: Perform a duplicate backup job so that you have redundant backups of the data in your deduplication storage fold...
Backup and Recovery

    If you are going to do that, which is a PITA...  I would suggest then, B2D with retention that allows you to get it to tape.  I would also duplicate the B2D to the dedupe folder, with the dedupe folder having a retention that is longer than the initial B2D.  Thats the beauty of deduplication, store more in less space, thus more full backups on disk for quick recovery.

    So Backup to disk, 2-3 day retention

    Duplicate to dedupe folder with 30 day retention

    duplicate from initial B2D to tape with longer retention as business requirements dictate. 

    I don't see a reason why you would even bother with incrementals to the dedupe folder, without the fulls.  The fulls benefit the most, not the incrementals.

As part of our policy, once the full backup to the dedupe folder is run, it kicks off a duplicate job to tape.

Is this what they mean?

I'm just trying to grasp the wording of that particular line and I want to make sure everything is set to best practices before I open a ticket concering slow backup speeds to the dedupe folder (700MB-1000MB/Min)
