ByteSync Frequently Asked Questions


What is ByteSync?

ByteSync is a data synchronization and backup solution. Lightweight and very easy to deploy, it offers outstanding analysis capabilities and synchronization performance.

Will ByteSync work on my computer?

ByteSync is available on Windows, Linux and macOS. It requires an Internet connection. See the ByteSync requirements for more information.

Can I use ByteSync for local or remote backup?

Both. In both cases, ByteSync uses rsync, a proven synchronization technology, to provide high synchronization performance.

Do I need to install a server to use the solution?

No. ByteSync operates on servers that we manage in the cloud. Users leverage easy-to-deploy clients, available in portable or installable versions.

What makes ByteSync so fast?

ByteSync integrates a port of rsync, the well-known synchronization solution in the Linux world. Thanks to this, only the differences are transferred during data backups.

What makes ByteSync so easy to deploy?

ByteSync relies on servers in the cloud. The client software uses only outbound HTTPS connections to communicate with each other.
Most of the time, the solution works properly without requiring firewall settings.

Is ByteSync secure?

Yes, connections between client software and servers use HTTPS. Data exchange between session members uses dedicated End-to-End Encryption (E2EE). The server part is based on Microsoft's Azure Cloud and we apply the most rigorous market standards in terms of security.

Can you view the synchronized data?

No. All data exchanged via the software is end-to-end encrypted with AES-256. Neither we, nor our host, nor any third party can read the transferred data.

What are on-demand connection keys?

When you log in to ByteSync, you will be asked for your account email address and serial number. If you are using ByteSync with third parties and do not want to give them this information, you can use on-demand login keys. These are generated by the software and can only be used within the session you have created.

When will the solution be available?

The Open Beta of ByteSync will start at the end of March 2022. At the end of this "full-scale" test phase, the software will be available for regular purchase.

What can I do if I reach the quota in my subscription?

Each subscription, from the FREE version to the ENTERPRISE version, has a maximum monthly synchronization volume. Once this quota is reached, it is no longer possible to synchronize data with this license. If you need to synchronize more data than your license quota allows, you will need to purchase another license.
