question on veeam backup
-
I presume it works by being able to dedupe all backups against the other backups from other backup jobs. I have the compression level set to dedupe-friendly as opposed to "optimal" which is the default setting. I probably set it up this way because I probably read somewhere that windows dedupe was more effective than veeam compression, but I've honestly never done an A:B test to know for sure in my environment. Maybe my next step should be to configure multiple jobs to test the various likely settings that might be used and see what has the best overall storage ratio. That might help give more information about where should be, or at least the storage veeam.
I also just remembered that I had the thought a week ago or so that windows dedupe might be hurting my restore times and overall performance, and that might a reason not to use it (this thought applied to my file server too).

@Donahue That is used if you have a backup appliance, such as ExaGrid, that you are sending your backups to.

I think I remember reading that windows dedupe should have used this setting too, but that was a few years back and my memory is a little fuzzy.

According to Veeam:
If you plan to back up VMs running Microsoft Windows Server 2012 R2 and later, and Data Deduplication is enabled for some VM volumes, it is recommended that you deploy the Veeam Backup & Replication console and mount server on a machine running same or later version of Microsoft Windows Server with Data Deduplication feature enabled. Otherwise, some types of restore operations for these VMs (such as Microsoft Windows File Level Recovery) may fail.

@Kris_K yep, that was it!

However, like I mentioned a few posts up, I have considered not deduping my file server. I am also considering replacing it entirely with something different like NC, but I havent got that far yet.

So you're deduping the storage on the backup server AND running dedup on the fileserver?

currently, yes. And since my storage is all intermingled, it makes it very hard to know how much belongs to either. I don't like it and I am working on changing it all around.

Intermingled?
my backups and my production stuff for the most part are currently running on synology NAS's.

The OS doens't matter to Veeam beyond being Windows.
That's a good piece of knowledge.
