Question about Data Deduplication.

[Ninja]

I have a few questions about Data Deduplication.

1. Is Reverse Incrementals recommended for Data Deduplication?

2. My Setup:
Veeam Server - Windows Server 2016
(D: Drive) is for backup jobs.
(E: Drive) is for backup copy jobs (gfs).

Should I enable Data Deduplication for drive D or E? or both?

Hello,
and welcome to the forums. Just to make sure, you are talking about Windows built-in deduplication feature?

1. it makes no difference which mode you use

2. what ever you like. The only thing that I would not do is putting primary backup jobs and backup copy job target on the same server. If that server breaks, then you loose everything.

I can recommend to watch out Microsoft limitations about file-size and use per-VM backup chains. And at least Server 2016 if we are talking about Windows deduplication.

Best regards,
Hannes

1. Not recommended, you'd better use forward incremental with periodic full mode (old, but gold). Thanks.
