DLO 7.6 Dedupe Backups vs Non-Dedup Backups

Hello, I am still fairly new to DLO 7.6. I have a few questions: 1. If I am reading correctly a profile configured for dedupe cannot be configed for local backups (LUDF). Is this correct? 2....

    1) No as a LUDF is needed when DeDupe profile is configured. DeDupe occurs only when the file is completely new, meaning the first revision of the file will be deduplicated. Once this file changes, the backup mode switches from DeDupe to Delta. And Delta mode requires the DUDF (Desktop User Data Folder) as the delta changes are first computed on the DUDF and then copied over to the NUDF (Network User Data Folder).

    2 & 3) The DLO Admin service & the maintenance service are required always whether DeDupe is being used or not. If DeDupe is being used, then the DeDupe services come into the picture.

    4) DeDupe helps in saving the network storage space (and thereby reduces the data transfer over the network) & is beneficial especially when multiple copies of a file exists across clients.
