    Article Summary

    If you use an operating system (OS) that is not supported by Backblaze, then your backups can either not properly function or not back up altogether. Backblaze recommends that you always update to the most current supported version of your OS. You can find information about Backblaze supported OSs here.

    Using Unsupported Operating Systems

    You can expect the following behavior if you use an unsupported OS.

    • The Backblaze client notifies you that you must upgrade your OS, and you must update the Backblaze client. 
    • Automatic updates to the Backblaze client may no longer work depending on the OS and the Backblaze client version number. 
    • In some cases in which the OS and Backblaze client version are not compatible or they are severely out-of-date, backups no longer occur and pop-up dialogs guide you on what to do next. 

    Unsupported Operating Systems

    Backblaze does not support the following OSs.

    Windows

    • These systems are not supported, and you cannot install the Backblaze software on them.

    Alpha, Beta, Prerelease, and Preview Systems

    • These operating systems are not supported. While you can install the Backblaze software on them, the features, performance, and validity of backups may not have been tested.
