Instant Replicator is a real-time folder synchronization tool that can automatically keep two or more folders synchronized around the clock. It works silently in the background to monitor and replicate folder changes across your network, according to the rules that you set.
iRep comes with 5 built in sync actions: Backup, Mirror, Merge, Distribute and Collect; and allows users to create their own custom sync actions. It also supports one-to-one, one-to-many and many-to-one folder synchronization.
Other features include: file filtering (by name, size and/or date), skipped-files-free synchronization, detailed logging, email notifications, pre and post-sync command execution, quick-sync, and scheduled unattended sync tasks.
