HOW TO
Distributed collaborations allow ArcGIS Online and ArcGIS Enterprise users to share content between organizations. Hosted or reference feature layer items can be shared to a collaboration workspace with the option to copy data. When sharing a feature layer by copying data, a new item is created for collaboration participants and the copied data is used to publish a feature layer for collaboration participants. The original feature layer can be edited by the owner and the changes made are synchronized to collaboration participants at a scheduled interval.
Synchronization of edits by collaboration participants utilizes replicas to identify which feature layer must be synchronized. Due to various reasons, such as multiple synchronizations between collaboration workspaces, stale replicas may be created. A stale replica is a replica that has not been synchronized in the last 30 days. These unused replicas consume disk space unnecessarily and cause performance issues.
Periodically, Portal for ArcGIS runs a task that checks for stale replicas. If stale replicas are detected, the following debug log message is generated:
The feature layers in your portal have '4' replicas that haven't been used for more than '30' days.
If the above log message is observed, it is advisable to remove these replicas using the steps described in this article.
