By default, if dbmlsync fails during a download it doesn't apply any of the download data to the remote database. However,
it stores the part of the download it did receive in a temporary file on the remote device, so that if you specify -dc the
next time you synchronize, it can more quickly complete the download. When you specify -dc, dbmlsync attempts to download
the part of the previous download that it did not receive. If it is able to download the remaining data, it applies the complete
download to your remote database, otherwise the synchronization fails.
If there is any new data to be uploaded when you use -dc, the restartable download fails.
You can also restart a failed download using the ContinueDownload extended option or the sp_hook_dbmlsync_end hook.
