Hi everyone,
I created a completely empty workspace in Microsoft Fabric that is no datasets, no reports, no lakehouses, no pipelines, and no usage at all. The goal was to monitor how the storage behaves over time using Fabric Capacity Metrics App.
To my surprise, I noticed that the storage consumption is gradually increasing every day, even though I haven't uploaded or created any new artifacts in the workspace.
Here is what I have done:
Created a blank workspace under F64 capacity.
Monitored storage daily via Fabric Capacity Metrics > Storage tab.
No users or processes are using this workspace.
No scheduled jobs or refreshes.
Has anyone else observed this behavior?
Is there any background metadata indexing, system logs, or internal telemetry that might be causing this?
Would love any insights or pointers on what’s causing this storage increase.
Thanks in advance!
Hi @WingsTvT
this seems to be a bug and has been reported multiple times.
having said that the unexplained daily storage increase in your empty Microsoft Fabric workspace appears to be caused by background system processes inherent to Fabric’s architecture, such as operational telemetry, internal logging, or maintenance tasks.
