Performs a download-only synchronization.
dbmlsync -ds ...
When download-only synchronization occurs, dbmlsync does not upload any row operations or data. However, it does upload information about the schema and progress offset.
In addition, dbmlsync ensures that changes on the remote are not overwritten during download-only synchronization. It does this by scanning the log to detect rows with operations waiting to be uploaded. If any of these rows is modified by the download, the download is rolled back and the synchronization fails. If the synchronization fails for this reason, you must do a full synchronization to correct the problem.
When you have remotes that are synchronized by download-only synchronization, you should regularly do a full bi-directional synchronization to reduce the amount of log that is scanned by the download-only synchronization. Otherwise, the download-only synchronizations take an increasingly long time to complete.
When -ds is used, the ConflictRetries extended option is ignored. dbmlsync never retries a download-only synchronization. When a download-only synchronization fails, it continues to fail until a normal synchronization is performed.
