While we don’t have a hard limit, we ask that you keep your average data usage under 1 GB. This will help ensure that all our customers are able to get the best performance from their free Omni Sync Server account. To determine how much data your OmniPresence folder is using, select the enclosing shared folder on your Mac, then Control-click (or Right-click) the folder to open the contextual menu and select Get Info to view the folder size.
If you are actively and persistently using more than this, we may ask you to reduce the amount of data you are storing. It is possible that we will implement a limit in the future, so it’s a good idea to keep your usage of the Omni Sync Server to a reasonable size.
If your workflow requires more storage than a gigabyte, you may want to either host your own server, or use a third party paid WebDAV host. In that case, the only limits are the ones you set for yourself!
If you are interesting in hosting your own server, we have instructions available here: Configure WebDAV for OmniPresence
