AVSbackup is a multi-thread application for reserve data copying. AVSbackup has a built-in system for automatic reserve copying of files and folders from their initial locations to the other folders and discs of the same computer or other computer of a local network. The application supports reserve copying of FTP and cloud storages (Dropbox, Box, Google Drive, SkyDrive) in both directions (download and upload) and reserve copying of databases to the file(s). Full, incremental and differentiated reserve copying is supported. Data can be restored both in the initial location and in the location selected by the user. AVSbackup maintains a log of events, which can be automatically e-mailed. The application supports program monitoring and manual task initiation via Web interface (the Internet connection is necessary). AVSbackup supports Zip compression of the reserved data, which is maintained optionally, with 256-bit AES encryption.
