Of course, just like any technology, synchronisation comes in with its issue. The most common issue with synchronisation is the connectivity, device, or remote infrastructure issue that leaves the data partially synced and you realize the consequences either later or right away. If it is right away, good for you!
Addressing synchronisation problems
You could retry or let the cloud provider know about this issue. Partially syncing the cloud can result in strange behaviour like downloading one message or file over and over again. The device may fail to download the new OS update or patch over and over again. Highly likely the crook is the connectivity issue with your Wi-Fi or cellular. If that is the case, you can find it out by moving the device to the area with a strong signal available. This typically does not prevent upstream connectivity issues but may need examination.
Problems with authentication
Another problem with synchronisation commonly faced is due to authentication, OS version issues, and incorrect configuration settings. In case the device won’t sync even if you are within a strong range of a signal, these things mentioned above are some of the things you want to look into. The problem may not always be on your end and it can be on the other end. The remote end of the connection. This could be the enterprise e-mail server, the entry point of the enterprise network. If the authentication fails to properly meet the requirements of the entry device, the device may prevent another such device from synchronizing.
Excessive data for synchronisation
Another common issue is when the bulk of data is trying to sync at the same time. This can clog or slow down the process and sometimes may cancel some of the data out. A device can sync its data from an enterprise app store as well as the vendor app store. Personal e-mail clients like Gmail, Yahoo Mail, and some third-party providers of something-as-a-service and cloud storage.
This could be prevented by properly configuring the device in a way that stops the other service from synchronising at the same time or the sources could be different data trying to sync to the same location at the same time independently. In an enterprise-level environment, this is the responsibility of the mobile device management team to take care of these issues and to deploy management and technical strategy which will ensure to minimize or completely eradicate certain conflicts between different synchronisation sources.
Even though the cloud has a downside, which one shines better in your business or personal case, hope this information will be handy to you.
