Windows Server 2012 Deduplication

If you’re thinking about Windows Server 2012, or maybe you aren’t, but you have a lot of uncompressed archive data like log files, syslog, documents, etc, check out the new deduplication feature. It’s a real charmer.

As an example for this post, last Friday I undertook to apply this new functionality to our syslog server.

With this in mind, I spun up a new VM, imaged it from our SCCM server with Windows Server 2012, and signed on.

EMC Avamar – Epic Fail.

Terrible initial implementation. High-downtime expansion. Unreliable backups. Absentee support. That’s EMC Avamar.

On the tiny upside, deduplication works great…when backups work.

In September 2011, our tragedy began. We’re a 99% VMware-virtualized shop and bought into EMC Avamar on the promise that its VMware readiness and design orientation would make for low-maintenance, high-reliability backups. In our minds, this was a sort of near-warm redundancy with backup sets that could restore mission critical systems to another site in <6 hours. Sales even pitched that we could take backups every four to six hours and thus reduce our RPO. Not to be.

Before continuing, I should qualify all that gloom and woe by saying that we¬†have had a few stretches of uneventful reliability, but that’s only when we avoided changing everything. And one of those supposed times, a bug in the core functionality rendered critical backups unusable. But I digress…
