关键区别 - 同步与备份
The key difference between sync and backup is that同步在两个方向上复制文件whereasbackup pushes files in one direction.从电子设备中丢失数据可能会令人恐惧。同步和备份设备可以节省很大的压力。但是同步和备份之间存在明显的区别。让我们仔细研究两个条款，看看他们所提供的内容。
What is Sync?
Data synchronization will ensure that data leaves a system storage entity, and will not fall out of harmony from its source. The purpose of synchronization is to modify and update data. If the data is modified on the application, you should make sure that the changes are communicated to the other systems that use the same data. Data synchronization creates consistency and harmony with all the other systems that have access to the data. Every business has the potential of benefiting from data synchronization. Data synchronization has also become very important due to increase in the use of mobile devices. Synchronization of personal data such asemailsand other operational data is useful for businesses to function effectively since it assists in preventing conflicts between data. Security is an essential feature of synchronization, compliance, trustworthy data and operational functions. Organizations that have synchronized data will enjoy high performance, cost efficiency, and reputation.
What is Backup?
Data backup is a process of duplicating data. This duplicated data can be recovered after a data loss. Today, there are many types of data backup services. Data backups help organizations and enterprises to ensure that their data is secure and critical information can be retrieved after a natural disaster, theft or other types of emergencies.

Since technologies like solid state technologies, wireless technologies have taken over, IT managers have the option of backing up data remotely or downloading large amounts of data onto small portable devices.

In addition to the above backup methods, there are new methods like failover and failback systems which operate automatically by switching data when the primary data is affected negatively. These methods help to protect data securely. As governments and businesses become more reliant on stored data, data backs have become more important than ever.
