File Synchronization

1.6.4
07 January 2013

Synchronize multiple pairs of folders or files.

Overview

File Synchronization is a utility that has the ability to synchronize multiple pairs of folders or files. It has been designed to be easy to use and quick to do the job.

It was based originally on the File Synchronization tool provided by Apple with the old Mac OS, but has a few improvements and features to help get the job done quickly and efficiently.

File Synchronization synchronizes multiple pairs of folders or files. It has been designed to be easy to use: choose 2 folders to synchronize then click the Synchronize button and you're done! However, there are multiple options when your needs get a little more complicated. The interface is easy to use and the application is quick to do any synchronization that you might need.

3 different synchronization modes to use depending on what you want to achieve:

  • Automatic mode: whenever the content of one of the folder you synchronize changes, the synchronization is performed so you can be sure that the 2 folders are always synchronized. You set it once and then forget about it.
  • Repeat mode: the synchronization is performed at a regular interval that you set in the preferences. Good when you're constantly making changes and don't want the folders to be continuously synchronized.
  • Manual mode: whenever you want to perform the synchronization, you select the pair in the list and click Synchronize. Ideal if you synchronize a folder that is on a remote volume that might not always be available.
2 different synchronization directions:
  • Bidirectional: changes in both folders that are synchronized are duplicated in both folders. Best when changes can occur in each folder that you synchronize.
  • Unidirectional: changes that occur in one of the folder you synchronize are duplicated in the other folder. If you want to have an exact backup of a folder, that's the synchronization mode to use. You can choose to backup the folder on the left or on the right.
Preview window:
  • See how many items are going to be copied and deleted and what the sizes of those items to copy and delete are.
  • Check what is going to happen if the synchronization is performed.
  • Decide which item is going to replace the other
  • Remove some items from the list from being synchronized.
  • Delete items you don't want to be synchronized.
Synchronization options for each pair:
  • Select the synchronization mode.
  • Choose the synchronization direction of that pair.
  • Set filters to ignore certain items.
  • Decide what happens with orphaned files and recently modified files.
  • Ignore warnings when both copies of the same file have been modified since the last synchronization.
  • Include or not invisible items.
  • See the status of the last synchronization session and when it was last synchronized.
Multiple sources for the synchronization:
  • Local disks.
  • Remote volumes shared by another Mac on your network or by a Windows computer.
  • iDisk.
  • USB flash drive.
  • Store login information for remote volumes so that they can be automatically mounted the next time they are needed.
  • Any volume you can access in the Finder can be used.
Additional information:
  • Can generate a log each time a synchronization is performed.
  • Error reporting gives you a description of an error so you can fix it.
  • Hierarchical views show you exactly where an item is in any list. Double-click an item and it will be selected in the Finder.

What's new in File Synchronization

Version 1.6.4:
  • Fixes a bug that would occur with a uni-directional synchronization on certain type of disk where when the copy would be performed, File Synchronization would invert the source and the destination in the progress dialog.
  • Fixes a display problem where the progress dialog would get random lines of text in it if you are using a mouse with a scroll wheel and would scroll the list of pairs under the progress dialog.
  • Fixes a problem where if you were to perform a synchronization and nothing would need to be replaced, the last synchronization date would not be updated.

I'm not reviewing this software because I wanted to comment on some of the other reviews, and because Backuplist+ does everything I need it to do. Several people have complained about the difficulty of synchronizing two folders using backup software. While that is generally true, Backuplist+ puts a pretty face on the *nix rsync tool that is designed for directory synchronization. It's free, can be scheduled, etc. In any case, I'm not knocking File Synchronization, because I haven't tried it (at least, not lately), but I can do what I need to do free with Backuplist+. I also found that the developer of Backuplist+ (whose name escapes me at the moment - something French, I believe) responded quickly and helpfully when I had a question about how to use the program.

It may be "compatible," but the bugs mentioned below have not been fixed, so it's half-assed compatible at best.

There are FREE alternatives available, so no reason to use this abandoned, buggy app.

Developer has not "dropped off the face of the earth," the website still works and they still respond to emails, so let's lose the drama.
However, they don't give a damn about keeping it updated and have a history of failing to fix bugs - see my previous post below and also the post from polocanada on Feb 21, 2014 in which the dev. says "Unfortunately, the issue hasn’t been fixed. We’re working on it. Stay tuned."
That was 19 months ago!

I've been using v1.6.4 for quite some time and didn't realize it hadn't been updated in nearly THREE YEARS. I was surprised when I saw that on MU and thought maybe they'd just forgotten to add a newer version.
But I checked the dev's website and they too show 1.6.4 as the current version.

I ran into a bug a few days ago in which FS fails to check if enough free space is available before beginning to copy files. I returned to find FS hung and I had to force-quit.
I figured out what was causing the problem and notified the developer, even though I really didn't think they'd care since the app appeared to be abandoned.

I received this ludicrous reply from them just an hour and a half after I sent my message:
"I’m not sure why you think it’s abandonware. It’s not. The problem you reporting is a known issue that we are tracking and hope to fix in an update. The big problem is that the App Store rules are constantly changing and getting stricter, so it’s harder to maintain older software. And, as you might be able to imagine, rewriting an application like this from scratch takes time. We’re not the size of Apple or Adobe.
So, the only workaround I can suggest for now is that you check in advance that there is enough space on your destination for the entire content of the source."

They were surprised that someone would think that their app, which hadn't been updated in over 2.5 years, was abandoned? LMAO!
The last time it was updated, Mountain Lion was the current OS.
If it looks like abandonware and smells like abandonware, it's probably abandonware.

And they said they were aware of the bug and are "hoping" to fix it in an update, but it's been difficult because they're a small company.
In my many years of experience, "hoping" has never accomplished a single thing. Looks like they've been hoping for years that this app would update itself.
Even individual developers manage to provide regular updates for their apps on the MAS, yet in almost three years this company hasn't managed to fix a critical bug that they admit to knowing about.

Don't give this developer any money because they'll just squander it on who-knows-what. It sure won't go toward updating their software!
It would be EXTREMELY foolish to buy this app knowing it contains at least two bugs and hasn't been updated in years.

Backups are vital, and you want up-to-date, bug-free software from a diligent, reputable company.
That is definitely NOT what you get with File Synchronization!

Developer dropped off the face of the earth and the registration process has to keep happening - some weirder serial validation unlike anything else I've seen. Code won't work anymore and can't get response.

Response from the developer regarding the issue I outlined below.. Since it's not fixed, if you are doing sync, be very very careful everybody because if you use USB drives and if that drive becomes not available, disconnected or whatever, you could potentially risk loss of files because they become deleted both on source and destination and go to trash bin without you knowing it (unless you have LOGING option turned on) Here is response from Laurent. I think the issue is critical, it's unfortunate it's still not resolved after about 1 year being known. That was about the time when the problem happened and still not resolved. RESPONSE: --------- Hello. Unfortunately, the issue hasn’t been fixed. We’re working on it. Stay tuned. -Laurent. ------------

Hmm, hope I don't double post, not sure why my post doesn't appear here. Has the issue with the disconnected volumes been resolved? In version 1.6.2 I had often the issue when one of the attached USB volumes became disconnected and as a result File Sync didn't see it so it has deleted files on the other paired volume. Here is what happened: 1) Volume 1 < --> Volume 2 2) Volume 2 becomes disconnected (e.g. USB switch failure) 3) File Sync can't find the Volume 2 and displays question mark, however it continues doing it's job (There is an option to stop at error - but I didn't notice it first). 4) When the sync finishes, I look into trash bin and there are thousands of files deleted from Volume 1. Looking at the Log, I see thousands of entries saying files on Volume 1 will be deleted because file on Volume 2 no found. This is unfortunately poorly done or what is it, I lost thousands of files by these destructive sync, till one day I discovered trash bin full of these files and log full of this mess. If the volume is missing then why does the sync operation continue to run.. I am just wondering if this has been fixed.

Version 1.6.4 has 2 bugs, one being very serious. Serious Bug: This only occurs when synchronizing my iTunes Library folder. Synchronization takes place, but then the dialog box changes to "Fixing Modification Dates..." and the program hangs. I've waited up to 15 minutes and this never changes. CPU usage is at a minimum. In order to get out of it I have to "Force Quit" the program. I saw something similar in version 1.6.3, but the dialog was "Fixing Permissions...". Same thing. Had to Force Quit the program. This is under OS 10.6.8 and only happens with the iTunes library folder. Bug 2: Version 1.6.4 What's New: "Fixes a problem where if you were to perform a synchronization and nothing would need to be replaced, the last synchronization date would not be updated." This was not fixed.

WARNING - version 1.6.3 has a serious bug: When syncing files, the window displays the wrong information - it has the "copy from" and "copy to" items reversed, making it appear as though you're copying in the wrong direction. The copy process is actually done correctly, but it can sure scare the hell out of you when you don't know! I notified the developer, but their lack of concern and failure to promptly correct this is alarming. Their response was "This is a known issue that we have already fixed. If you have purchased from the App Store, you'll have to wait a bit because there is another minor fix we want to do before submitting this update." So rather that than release an immediate update for this critical bug, they've delayed the release so they can include a "minor fix." Data integrity is paramount, and giving a false impression that data loss is occurring calls for IMMEDIATE action!

The more I use File Sync the more I like it. It handles all my back up needs. Sometimes I leave it to run overnight and when I get up all the hard work is done. I've never missed anything, it works like a dream (well more like while I dream ;)

For 6 years this has, together with 1 Password, been the most important utility on my Mac. Here is why: 1. You can synch to anything you can connect to. Be it across platforms f.e. beween a Windows machine and a Mac, be it via LAN, Firewire or any other connection you can make. 2. You need to run File Synchronization only on one computer. No need to install it on the other. 3. You can preview anything you do. You can see where Files are located, manually erase them if you do not want to keep it, or manually exclude one or more files from synching. 4. You can automatically exclude files you do not want, such as .db files with thumbnails of files which may be needed in Windows, but not on a Mac. 5. You can delete orphaned files automatically while excluding recently changed files so that you do not recopy files you just deleted from the other computer, but also do not delete files just generated on one. 6. You can even synch containers such as key chains. Of course you cannot synch actual database content (that would be asking a bit too much!) 7. The support is simply grand. On the few occasions when I needed him, Laurent, the author of the App, always figured out a solution for me - and always did so quickly. There are very few Apps I could recommend with equally little reserve! One feature might be nice for the future: If Quick Look could be enabled in the preview, there would be no wish open!

I second you on everything you said! File Sync running here for about 3 years, I have been relying heavily on it for my back ups and it has never let me down. It's awesome and works for me flawlessly churning over the boring stuff while I drink tea and go shopping and I can't recommend it highly enough! Five Stars *****
