UPDATE: the solution has been deployed for Odoo 18.0 and Odoo 19.0 - see https://www.odoo.com/documentation/19.0/applications/general/integrations/cloud_storage.html

Shared hosting type Odoo.sh deployments have a limit of 512 GB

Dedicated hosting types Odoo.sh deployments have a limit of 4 TB

Odoo has created a solution to move parts of the filestore to either Google Cloud or Microsoft Azuze, please contact your Account Manager for information about this additional feature.

This solution works well for databases containing a high volume of large documents or for databases that have grown so much in size due to widespread use of either attachments or significant use of the Documents App.

To give you a rough idea of how much data can be stored in 4TB, here are some examples:

• Approximately 1 million songs in MP3 format, assuming an average file size of 4 megabytes (MB) per song.
• Around 2,000 hours of high-definition (HD) video, assuming an average file size of 2 gigabytes (GB) per hour.
• More than 1,000,000 photos, assuming an average file size of 4 MB per photo.
