One of the best things you can do for yourself and your Mac is to have a good backup system. Time Machine is not enough. Neither is a clone backup. Online backups are tedious to get started initially, but good for a solution to a catastrophic problem with your Mac (flood, fire, theft, tornado, etc.). Those are the basic backup solutions.
In between nothing and a multi-tiered approach to backing up files is one that has become a staple on my home and work Macs. Automatic folder and file syncs. In use on my Mac today is a modestly priced utility called DropSync which watches files in specified folders and automatically syncs or backs them up to a target source.
DropSync starts out with a familiar backup utility interface. There’s the standard source folders and files on the left, and the target backup or sync folders and files on the right. Drag and drop starts the process. Choose to backup or sync everything you need from the source folder, excluding any files as needed.
That ease of use and simple initial setup makes DropSync particularly useful for those new to the Mac or who want to add to their backup plan without a lot of effort or expense.
Alright, that said, DropSync also comes with some power user functionality, including a file comparison browser, folder watching, options for symbolic links and permissions, and it works over a network (sFTP) and even handles by-directional sync (good for keeping Documents synced between a desktop Mac and a notebook Mac. DropSync uses Rsync technology and handles file backups incrementally– only copying or syncing files that have changed– which speeds up the backup process.
My favorite feature is the folder watch option. Once you’ve created a folder backup or sync, have DropSync watch the folder on your Mac. Any file changes– added to or deleted from– the folder will be instantly copied or deleted on the synced folder.
DropSync has a number of other useful backup and sync functions. It’s available on the Mac App Store but the developer also has a free trial version, a substantial help book, support, and an online support forum. There’s much to like here, especially considering the nominal price tag.
