Abstract: A system and method is provided for selecting a backup plan based on sampled metadata. An exemplary method includes sampling metadata of files on a computer during a predetermined time interval, wherein the files are backed up to a storage server in accordance with a first backup plan. The method includes predicting file usage dynamics for a time interval subsequent to the predetermined time interval, based on a combination of the derivative features and the attributes of the metadata, and comparing the predicted file usage dynamics for the time interval with file usage dynamics of the predetermined time interval. In response to determining that a difference between the predicted file usage dynamics and the file usage dynamics of the predetermined time interval exceeds a threshold difference, the method includes selecting a second backup plan for the files, and backing up the files to the storage server accordingly.

Abstract: A processing device sends a request from a remote access client to a first remote application server to access a first application being hosted by the first remote application server, receives instructions from the first remote application server to display a first application window within a browser window of a browser on a display of the client device, creates the first application window within the browser window based on the instructions. The processing device sends a request to a second remote application server to access a second application being hosted by the second remote application server, receives instructions from the second remote application server to display a second application window within the browser window, and creates the second application window for the second application within the browser window based on the instructions. The second application window is displayed within the browser window together with the first application window.

Abstract: Disclosed are systems and methods for managing an application executing in a remote session. A user device (e.g., mobile device) creates a control communication session for an application executing within a remote session established between a remote application server and a client device.
