I have been pushing 5 years of sales orders and invoices to an Azure cloud. Once every week the refresh will fail and data will go missing. I will have 5 years of good data and a few days of missing data that no number of refreshes will bring into the database.
To solve this, I have been deleting the tables and reloading the data (which takes a few days) and I get charged from Azure for data transfers.
Is there a way to force OpenSync to refresh from a starting date that it thinks it has already transferred? In other words, is there another way to recover from a syncing crash besides rebuilding the full database?
