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 Storage. I already set it up on our DEV Server but not yet on our test server. But i do not find that much about performance and support of deduplicating the BLOB drive. Also - how can i change the shred size of existing files? At the moment they are set to the 64k design size. Best regardsStephan

What backup strategy are you using? The proper way would be to establish a proper SQL backup strategy, e.g. taking T-Log backups on regular intervals (we use 15 minute intervals) and full backups as appropriate, e.g. once per day, once per week, whichever works.Farms in excess of 2TB aren't difficult to manage. In a general sense, business users do not want to 'archive' things. We see this with file servers all the time, with irrelevant data ranging back to pre-2010 or even pre-2000.I suppose my point is you're introducing significant complexity for no _good_ reason. You're also not 'saving' yourself any work, only adding more. You still have to back that data up and you still need to maintain SQL database backups. Instead, now you're having to maintain two backups and sync their backup intervals. And maintain the RBS maintainer job.

I believe this is only possible at the content DB level not site collections. If you have one site collection per DB then sure.https://docs.microsoft.com/en-us/sharepoint/administration/migrate-content-into-or-out-of-rbs To modify the shred size, you should modify the FileReadChunkSize and FileWriteChunkSize properties. $webapp = Get-SPWebApplication http://yourwebappurl/$webapp.WebService.FileWriteChunkSize = 4194304$webapp.webservice.Update() Some references:https://blogs.technet.microsoft.com/wbaer/2012/11/12/introduction-to-shredded-storage-in-sharepoint-2013-rtm-update/https://view.officeapps.live.com/op/view.aspx?src=http%3a%2f%2fvideo.ch9.ms%2fsessions%2fspc%2f2014%2fSPC416_Baer.pptxhttps://gavinmckay.wordpress.com/2015/01/08/howto-configure-shredded-storage-in-sharepoint-2013-using-filewritechunksize/

Thanks Doug for your response. Do you have any input for the deduplication of the BLOB files?

Dedupe would be a product of the RBS provider and/or file system (e.g. NTFS dedupe).I'd ask why you'd be using RBS. It is largely irrelevant, now.

Hi Trevor, why do you mean it's irrelavant?The deduplication feature will save me (if allowed) about 2 TB of space and the RBS feature will help me to stay within the 200GB DB sizeWe are having SharePoint 2013 on prem with 4TB+ data and mostly office files 2mb+.Sorry for the late response .. i did not get any mail Best regardsStephan

$webapp = Get-SPWebApplication http://yourwebappurl/
$webapp.WebService.FileWriteChunkSize = 4194304
$webapp.webservice.Update()
