If there’s one thing that dominates my Mac backup plan it’s the number of hard disk drives. Each Mac has a fully cloned disk drive, a backup drive for select and important files, and even backups between Macs.
Through the course of the day I want backups beyond Time Machine. For that, there’s a little known but useful Mac app called Sync Folders (available in Free and Pro versions).
What Sync Folders does is priceless.
It syncs files within a folder to another folder. Big deal, right? Except that Sync Folders does it automatically. If a file changes in your source folder, it gets updated in the target folder (which can be on your Mac or on a separate disk drive, or a remote network computer, even to a USB or memory card).
That’s it. It does more, but that’s the big pony in the circus– automatic synchronization of files between folders. Setup is simple. Select the source folder. Select the target folder.
Each folder you want to sync becomes a task, and tasks can have filters, and a schedule, as needed.
Other functions include the options for filters, viewing changes, viewing logs, and even using a virtual private network connection to sync folders on a remote Mac. These are all well and good and somewhat common, even on inexpensive apps like Sync Folders.
The real value is the automatic folder sync. It’s a feature whose time has come. Think of it as on-the-fly Time Machine for critical files that need to be backed up instantly.
