Abstract: Disclosed is a method of file recovery. The files are generated by an application 5 running on a client server system 1 with a client 100 with a client back-up tool 110 and a server 200 with a server back-up tool 210. The application files are backed-up as data in the back-up server, the files are restored from the back-up server to the back-up client based on the file usage behaviour of the application. If the file priority class information is missing, then all the files of the back-up data are restored. If the file priority class information exists, then files of a highest priority class are restored at the back-up client and file stubs of all remaining files of the back-up data are created on the back-up client. Control is then returned to the application, and the file usage behaviour of the application is monitored and analyzed. The files are classified into different priority classes based on file usage behaviour. The file stubs at the back-up client are replaced with corresponding file content from the back-up server during runtime of the application based on certain criteria.
