Replia much larger than backup

Post by Steve_za »

I'm trying to find out why replicas are so much bigger than backups, I have a 3TB SQL server that only does incremental changes of about 60GB per day on the Veeam backup, but it does about 300GB on the replica. The jobs run directly after each other so it is not because data has changed on the disk. This is causing issues, as the replica has to go over the WAN, and is making the job run outside of it's allowed window.
support case number is 00525124.

Steve, do you have a proxy server deployed in remote location? The issue might be in the fact that in the absence of proxy servers deployed in both locations replication data would go between them uncompressed. This is not the case with backups, where data is always sent to the repository after being compressed.

Not only this will allow for sending data in a compressed format, but with a proxy server on the target host hotadd transport mode could be used to populate target datastore with replica VM data.
