At the weekend I suffered from performance issues
Normally, I have no issues, but on the weekend concerned I was running Full backups of our VMDK servers, normally we do a Incremental/Synthetic Full and once a month
run a Full.
At the same time normal agent backups were running and Synthetic Full (normally these are 2000+ GB/hr, but I was getting as low as 20GB/hr) and their performance was awful, kill the VMDK backups everything back to normal
I believe my DDB speed is okay at Average Q&I time of 340ms
This got me thinking about how the deduplication of the backup is configured
My initial question is my VMDK Backups are configured 'Enable Deduplication' -> Generate Signature on Media Agent
For my Agent Backups such as File System, I have this set to 'Generate Signature On Client' and I see on the client some CV_CLDB* files
So, if the signature is being generated on the Media Agent with the VMDK, is this directly with the DDB?
If I set the VMDK backup to 'Generate Signature On Client', where would it create these signatures, against the proxy?
Would it actually assist performance?
