Each time you start the management console, Acronis Backup checks whether a new version of the software is available on the Acronis website. If so, the software provides a link for downloading a setup program of the new version.
To check for updates manually, start the management console and then click Help > Check for updates. In that window, you can also disable the automatic checks for updates.
Another way to enable or disable the automatic checks for updates is to configure Acronis Administrative Template. In this case, the parameter value set in the administrative template will supersede the setting in the Check for updates window. For more details, see "Parameters set through administrative template" in the product Help or the User Guide.
For information about updating Acronis Backup, see the "Update" section (for local installation in Windows) or the corresponding installation section (for other ways of installation).
