Refreshing Copied Sources and Targets

Cloudsync prevents refreshes between targets that are improperly copied, or cloned, which could cause the system to become inconsistent.

A synchronization system includes a single source database, a set of target databases, and a set of copy files. The Cloudscape synchronization software automatically maintains the necessary relationships between these components. To ensure proper operation, follow these simple rules:

  • Do not clone a target database and refresh both the original target and the cloned target. To make a new target database, always start from a copy file. It is okay to move a target database.
  • Do not clone a source database and refresh targets against both the original source and the cloned source. It is okay to move the source database (provided, of course, that its refresh address does not change).

If either rule is violated, Cloudscape detects the situation and reports an error during refresh.
