ByteSync Reference Manual


Thank you for using or taking interest in ByteSync, our fast, lightweight and secure data synchronization and backup solution. We hope you enjoy the software.

Available with the same features on Windows, Linux and macOS, ByteSync offers 2 modes of operation:

  • Cloud Synchronization to synchronize data remotely via the cloud in a dedicated and secure session. Up to 5 remote or local clients can exchange data.
  • Local Synchronization to synchronize data between local network machines. In this case, only 1 client takes part in the session.

Only a few steps are required to deploy ByteSync. When using it, you will discover its simplicity and relevance, you will easily define advanced backup rules and you will benefit from its multidirectional synchronization performance.

ByteSync: a fast and powerful synchronization and backup solution

For both Cloud and Local Synchronization, ByteSync leverages rsync algorithms to deliver exemplary comparison and synchronization performance. rsync is a well-known data synchronization solution built on Linux. It is unique in that it calculates detailed file fingerprints that allow it to synchronize only identified differences.
Thanks to its integration with rsync, when ByteSync synchronizes files, only the parts that differ are transferred. As the volume of data increases, this process saves more time. See the Wikipedia rsync page to learn more about this utility.

Furthermore, while other backup solutions often only allow you to synchronize data between 2 separate repositories, ByteSync offers the possibility to select multiple data sources. In Local Synchronization, up to 5 folders or files can be selected. In Cloud Synchronization, up to 5 clients can select up to 10 folders or files.
Synchronization rules can be defined on an item-by-item basis or conditionally based on the properties of the files in the different data sources. The ability to compare and synchronize data is increased tenfold! ByteSync addresses many real-world use cases that may arise when implementing your backup strategies. Here are some possible examples:

  • 1-to-1 synchronization or backup
  • A to B and C synchronization (double backup)
  • Synchronization A and B to C, D, E (triple backup of 2 data sources)
  • Synchronization in star or circle. For example, A to B, B to C, C to D, D to E, E to A.

ByteSync: a flexible and secure remote synchronization solution

One of the particularities of ByteSync is that it relies on the Cloud for the remote data exchanges that take place in the Cloud Synchronization. The software uses outbound HTTPS connections and online hosted services to communicate and transfer data. Unless you are on a very highly secured network where outbound connections require permissions, there is usually no network configuration or firewall settings to be made.

To use ByteSync, there is no server to deploy and maintain. Just run the client software and connect it through the built-in session system.

Because your data is your property and only yours, security and privacy are at the heart of the solution.
All exchanges between clients and ByteSync servers are secured by HTTPS. Data exchanged between members of a single Cloud Synchronization session is secured by a session-dedicated end-to-end encryption based on the AES-256 encryption algorithm. Neither the ByteSync team, our host, nor any third party can read the data being transferred.

ByteSync’s servers and online services are securely hosted by Microsoft Azure, the Microsoft Cloud Platform.
