v6: replication across WAN: compress and dedupe?

[patrickbuller]

I am running v6. When running a VM replication job across the WAN, with a backup proxy on both sides of the WAN, is the data compressed and deduplicated across the WAN? As documented below, it seems that there is a discrepancy between the FAQs and slides from a webinar about this.

FAQ
Q: Does deduplication work for replication, or for backup only?
A: No, because replicas are created in native format (uncompressed), deduplication is not applicable to them.

Slide 9 - Replication Architecture
Uses proxies servers at source and target sites
- Source proxy (VM or physical)
-- Compresses and deduplicates the data
- Target proxy (VM or physical)
-- Decompresses the data

I'd appreciate some clarification. Thanks!

Hi Patrick,

Actually both answers are correct let me clarify it further...

In case of replication, deduplication and compression only applies while VM data is in-flight between source and target site (to reduce network traffic). On the other hand, the replica VM itself is stored in native (uncompressed) format - just like the source VM. Hope this makes sense.

Thank you!
