BASK is a synchronization based backup and restore utility. It allows you to specify a source and destination, along with a mapping, a pattern to include, and a pattern and folders to exclude. You can determine file set differences through the date, time, and size of the source and destination files; by checking the source file's Archive attributes; or by comparing a single file's version number in the source and destination folder. With its nineteen file set operations, you can backup, restore, and delete files in a number of useful ways, and even span them across multiple disks. Automatic operations, scanning alerts, and conditional operations help automate the process. Full command-line support and help are included.
