Guesstimate Disk Space Needed to run Analytics

DHIS2 Community,

Is there any way to guesstimate the disk space that will be needed to run a complete Analytics with DHIS2? I obtained a dump of 12 GB that was restored on a 150GB system and Analytics majestically failed because Postgres could not write on block device. This DHIS instance grows with data pretty fast and the purpose of my question is more to understand how this process works (running Analytics) to make better provisioning for the growth of the system.

Thank you for your help with this.
