 We strongly recommend creating an alert for Disk Utilization. A threshold of 90% is usually reasonable. By far the most common operations issue we see is servers running out of disk space as large media attachments pile up. If your server runs entirely out of disk space, it can crash and become unresponsive. It is best to upgrade your storage plan before this happens.

 Forms with many large media attachments can fill up your droplet's storage space. To move your Central install to external storage, follow these steps:
