SyncTime is the simplest solution to synchronize your files. Did you ever wish you could easily keep up to date all your backup copies, distributed across many devices?
SyncTime will just do it.
SyncTime is capable of so many things, yet is so simple to use. From manual, scheduled or completely automatic syncing, to background syncing, bidirectional syncs and sophisticated filters, you'll be able to set up your syncs exactly as you imagine.

* You can try out the free SyncTime Lite in order to find out if this is the right solution for you. *

You can create as many sync items as you need and customize each one individually. A sync item mainly consists of two folders: a source and a destination. You can choose any two folders reachable in the Finder: they can be located on your Mac, on an external drive, like a USB stick, or even on a remote server. Among the possible options you will find:
• four overwrite policies: (1) overwrite only if the source file is newer than the destination file, (2) overwrite if the source file has a different timestamp, (3) overwrite always or (4) never overwrite.
• three sync types: one-way sync (default), two-way sync (merge source and destination) and one-way move (delete the source files after a successful copy to the destination)
• remove files that don’t exist on the source anymore
• background syncing: changes performed on your Mac are monitored in real time in order to keep the destination always up to date
• start to sync automatically whenever source and destination become available or sync once a day, a week or a month
• every sync item can be dependent on other sync items: it will trigger the dependencies and run automatically when they are all completed
• files to be overwritten or removed can be moved to the trash or to a custom backup directory
• exclude hidden files, files with names or tags containing specific words or matching a regular expression, and selected files. Or exclude the root directory and specify just some included files.

Other features include:
• changes have to be confirmed by default and you can inspect the files that will be added, overwritten and removed and preview them in QuickLook
• a running sync can be canceled at any time
• syncs run in parallel
• your Mac can automatically be set to sleep or shut down after all syncs have finished (requires the respective Applescripts, which you can find on the website).

Does exactly what i need, nothing more, nothing less. However...

like i said, it does exactly what i need. i want to love it but a crippling issue as arisen and that issue seems to be a memory leak. i have it set to start at login and my imac only goes to sleep, never logging out as i’m the only user. i leave the sync window open to monitor the progress. after a few days and sync routines, activity monitor shows the memory allocated to it has ballooned. on startup it consumes about 85MB with my syncs configured. after 3 days, the memory allocated had ballooned to over 20 GIGABYTES. it seems it holds all of the files it transfers but never lets them go after the transfer is complete? i only noticed this when i woke up my iMac from sleep this morning and it was acting sluggish despite only being 2 weeks old with a fresh install of High Sierra.

i’ll keep a closer eye on it over the next week and update the progress. if the problem persists, i’ll escalate it to the dev. if it doesn’t, i’ll edit this out of my review and adjust it accordingly.

Works Great on Campus Network!

I am using the SyncTime to sync documents between my office Mac and an SMB connected campus server. I have used many different applications over the years, and all work to differing degrees when it comes to unmounted drives. Partly as a result of changes to the campus network server. What I like about Syncmate, at least right now, is the clean interface and that it will try to automatically mount the drive. If I havent enabled the VPN, it just waits until I have and then runs a sync. It also seems to do a good job of offloading the mount process to the system rather than trying to handle its own passwords. That might be accidental or intentional, but it is less hassle than trying to figure out the login sequence required by an app. My needs are pretty simple, which is reliably sync a folder of powerpoint slides ready for class, and it is currently doing that well.

This is the Best and only Sync Program I Trust

This program is simple to setup any way you want it, without too many or too little settings. It has proven to work solid on everything I throw at it, it doesn’t lose any data, syncs 2 8TB hard drives with large movie files, 200GB iTunes library, 300GB Pictures, as well as all kinds of other data. Synctime also somehow manages to copy data faster than copying and pasting with my Mac. Then the programmer has the best customer service ever. I recommend this program to anybody wanting a seriouse and solid syncing program. I’m a computer tech for a living and this is the only program I support and recommend to all my Mac customers.
