Short description of InSync Backup Software 8.1.70: InSync is a directory synchronizer that allows you to rapidly make identical copies of directory structures and all files within. This is useful in performing backups and propagating data from one machine to another. Using InSync you can define and run multiple jobs that can specify one or more source directories, each which can be synchronized to one or more target directories. 1-way, 2-way, and backup synchronization modes are supported.
