As of April 1st, 2019, SOS Online Backup will no longer support backup of Windows XP and Windows Server 2003 endpoints, regardless of installed version of the application. For other versions of Windows, latest updates are recommended to be installed.
Additionally, as of April 1st, 2019, SOS Online Backup will no longer support outdated application versions of desktop applications: Windows clients below v6.8 and Mac clients below 3.7.
What is happening and why?
As we release new versions of our Cloud Backup software to include additional features, better performance, and enhanced security, these versions are not always compatible with older operating systems. In fact, Microsoft stopped supporting Windows XP in April, 2014 and stopped supporting Windows Server 2003 in July 2015.
Currently, Windows XP and Windows Server 2003 utilize a TLS v.1.0 protocol and 3DES, AES128 ciphers (encryption algorithms) that pose vulnerabilities. To learn more about why Microsoft is encouraging its users to update from TLS v1.0, please read this blog from Microsoft: https://blogs.microsoft.com/microsoftsecure/2017/06/20/tls-1-2-support-at-microsoft/
The Transport Layer Security (TLS) protocol is intended to serve as a secure link between a client machine and the server or Web application. While SOS Online Backup supports a variety of other, more secure, TLS protocols, we have decided to stop supporting the TL1 v1.0 due to security concerns.
Phasing out outdated versions of our software and disabling vulnerable 3DES and AES128 ciphers allows us to strengthen the security of your data.
The National Institute of Standards and Technology (NIST) advises all users to migrate to stronger ciphers: https://csrc.nist.gov/News/2017/Update-to-Current-Use-and-Deprecation-of-TDEA
Option A (Preferred): If you are running SOS Online Backup on a Windows XP computer or with Windows Server 2003, you need to update your operating system to Windows Vista or a later version by following the instructions on Microsoft’s support site.
Option B: You can put the data on a network share that is accessible from other computers in your network. SOS Online Backup software can be installed on another computer and you can continue backing up your data from the network share.
