# Incoherent disk space / bandwith usage

Hello,

Can you help me understand the logic of the relationship between these numbers ?
These are from my node dashboard, over the last 3 days. I usually peek into the dashboard at breakfast, and this is what I get:

April 16th : 62,77TBh disk space used, 245GB ingress, ~600 GB “disk space remaining” (the following morning)
April 17th: 39,36 TBh, 207 GB ingres, ~290 GB remaining
April 18th: 76,18 TBh, 217 GB ingres, ~70 GB remaining

Doing some maths:

• Between April 16th and 17th, there is 23,41 TBh less. That would need nearly 1 TB deleted at midnight and never replaced, right ? (or 2TB deleted at noon). Since only 245 GB ingres was received that day, I should have seen a big increase in my “disk space remaining”, which is not the case. Instead, I’m using 310 GB MORE than the day before, which is still more than what I have downloaded…
• Again, between April 17th and 18th : a 36,82 TBh difference, meaning somehow 1,5 TB of data magically appeared on my node at midnight on the 17th. Or 3TB at noon. The 207 GB of ingres I got on that day are far from filling that much space, so where does the rest come from ? But this time the “disk space remaining” evolution seems coherent.

Is my math correct ? And if so, how can we explain the inconsistency in numbers ?

As a side note, I’ve also monitored the size of the trash folder : it’s never more than 6 Gb. So I doubt it’d be related with deleted data.

Thank you
