I have read several article about shredding and RBS like 1, 2,...

in my (probably wrong) understanding there is conflict between RBS and shredding. for example if i set RBS limitation for 1MB, files never go to RBS. because there are shredded in 64 KB and so there are smaller than 1 MB, so the only way to use RBS is changing FileWriteChunkSize property that affect storage growth like example in 1. as a result i must choose between using RBS or shredding. it would be great if someone could help.

You already found out all relevant parameters:

  • if you use the Microsoft FILESTREAM-Provider to configure RBS, your only option is the filesize to determine if a file should be moved out of the ContentDatabase
  • SharePoint 2013 has the new feature ShreddedStorage. Default is to create 64KB chunks of every file ("Shred")
  • So if you want RBS to externalize files larger than 1MB, you have to configure the FileWriteChunkSize to a value larger than that.

Your Options:

  • Stay at the FILESTREAM provider and modify FileWriteChunkSize to your needs.
  • Buy a 3rd party RBS-Provider. Those tools are able to schedule jobs which can move content out by a lot of other parameters than only the file size. You can also choose the filesize and you are not affected by the FileWriteChunkSize problem.
  • Rethink if you really need RBS. Unfortunately you did not specify any infos about your planned environment.
  • Thanks for great explanation,as i got because of complexity of deployment and non-integrity Backup process of 3rd party RBS-provider we should discard using that and handle our multimedia files in other way than SharePoint.
