SharePoint 2013 - Remote Blob Storage and Deduplication / Shredded Storage Migration

Hi there, i only found 2 blogs mentioning that this is possible. But is it also supported? Anyone is using this configuration? I want to move most of our sitecollections "to" Remote Blob Stor...

General usage scenarios support is 4TB. It's all about storage performance. There is no 200GB "limit" (except with RBS, there is a _hard limit_ of 200GB; your un-deduped is the size you need to calculate). Having run many farms with CDBs in excess of 1TB, as long as your storage subsystem isn't made of just a couple 7200 RPM consumer SATA drives, you're likely fine to meet the 4TB IOPS requirements.

Hi Trevor,

i know these limits are recommendations from MS and i can deliver the IOPS at the moment.

200GB limit in a RBS enabled content DB should be easy to achieve.

I came to RBS from an archiving project.

My main focus is on deduplicating SharePoint files to make the "archived project sites" available to our users until they get deleted after 5 years after project closing. (which is a requirement of our management)

On the other hand i want to use Azure Site Recovery but the the SQL Server containing the content DBs was not "compatible" because of too high IOPS.

200GB in a non-dedup'ed RBS content? You're also putting the overhead of RBS management and backup/recovery. It's simply not worth it when you could do archive in-place.

I mean, it's your farm, but Microsoft's RBS was designed for people running SQL Express when it was still supported to work around the MDF file size limit; it wasn't designed for enterprise scenarios.

  I thought that RBS is a good way to keep your farm (and sql server) with the performance you want.
  I read many blogs as well as watched videos like this:
  https://channel9.msdn.com/Events/SharePoint-Conference/2014/SPC424
  This kept me thinking that files that are bigger than 1,5mb would be better stored on file system than in a database. I thought OneDrive in the cloud is also using BLOB storage?
  
  But inplace archiving the sites would not shrink the used space or do i understand it wrong?

    I don't think it is fair to compare ODfB/SPO services with on-prem capabilities. They use Azure Blob Storage which isn't quite the same and runs through a bunch of different code paths (see https://thesharepointfarm.com/2015/08/azure-blob-storage-for-sharepoint-documents/). You can have the performance you need to by monitoring your SQL Servers; using SSDs or other flash storage is going to be the best bet, performance-wise. No site size will "shrink" if using RBS or not.
