I have a Mac laptop and a PC desktop at home. I also use Bootcamp with Windows XP and have several virtual machines (Vista, Ubuntu) installed with VMware and VirtualBox.
I want an easy way of syncing my files from the Mac at home with the PC at work without having to leave the Mac open all day long, like with Windows Live Folder Share.
- When running Windows in Bootcamp I don’t want to buy MacDrive to access the Mac partition
- When on the Mac I don’t want to buy Paragon NTFS just to work on a few files.
- I want to transfer files between my Mac and desktop PC and I don’t want to go through the hassle of setting up a home network between the two and fiddle with the sharing options – I may forget to unshare folders on my Mac, inviting everybody to steal my files when connected to a hotspot.
- When playing with Virtual Machine software I don’t want to learn how to use VM shared folders. I want an easy way of transferring a bunch of files on all my virtual machines, no matter what VM software I use.
Looks like I need some syncing software: Dropbox and SugarSync.
Interface
DropBox has no interface. After installing DropBox you get a DropBox folder in you Documents folder. It may look like any other folder but it’s actually special. Every file you drop here will be automatically uploaded into the cloud (Amazon S3 to be more specific) and then downloaded to all the computers that you linked to your DropBox account(when they go online, or instantly if they are online). The same happens when modifying or deleting files. A green checkmark will be overlayed on the icons if the files are up to date (on your machine and online) and a blue arrow when files are syncing. Unfortunately there is no indication of transfer progress, speed or ETA. Growl Notifications/Tray Tooltips when syncing is complete is all you get.

SugarSync’s interface is quite pleasant. You use it to set up the folders you want to be synced and backed up online. There is a DropBox equivalent also – the Magic Briefcase. It’s a folder in you Documents that acts exactly like the DropBox folder- all your files you drop there will be synced on all the computers you installed SugarSync on. There is no graphic representation of what is happening to the files like you get in DropBox, but if you return to SugarSync Manager you are able to see details about the transfer: speed and ETA. Too bad you can’t hide SugarSync Mac client from the dock, and access the manager just from the menu bar.

Supported platforms
Dropbox works on Mac, Windows and Linux, while SugarSync works on Mac,Windows and Phones (iPhones,BlackBerrys). So no Linux love from SugarSync.
Usability
When using Dropbox you are actually using just familiar software: Explorer, Finder or Nautilus. There is nothing to configure, just start to drag & drop files in the DropBox folder. You can access functionality like sharing or viewing all the versions of a file by right clicking on the file and choosing the appropriate item in the DropBox submenu.
SugarSync has a nice and intuitive interface (SugarSync Manager) but I’d rather it took a transparent interface approach like DropBox did.
Sync files on multiple machines
DropBox and the MagicBriefcase of SugarSync work flawlessly across platforms with no user intervention.I tested all the scenarios posted in the challenge, and both programs performed marvelously.Both offer automatically resume support so don’t worry if your connection drops or you need to turn off your machine when syncing.
Backup
DropBox is not really suited for backup. You can’t select which folders or files you want to backup online. You only have the DropBox folder where you drop files you need to be synced with other computers. You can use it for backup though: just copy the files in the DropBox folder but now you will have two copies on the machine you want to back-up, and a copy on all your other machines when they sync.A little to redundant for my taste.
SugarSync is a good backup solution. In the SugarSync Manager you can add which folders you want to back-up and sync online. Any changes you make in these folder will instantly reflect online and vice-versa. Only the files in the MagicBriefcase will be synced across all of your computers.
Access your files online
DropBox and SugarSync offer similar web interfaces where you can download or upload files. The days of emailing files to yourself or putting them on flash sticks are over.

As expected, in SugarSync you can choose between the computers you backed-up. The web interface looks a lot like the offline SugarSync Manager.

Share files
In DropBox you have a Public folder. All the files dropped here get a public access link that you can send to your friends by IM or e-mail. To reveal this link just right click the file and choose DropBox->Copy Public link. The link is now in you clipboard, just a few keystrokes away from pasting it in your IM window. For sending large files to your friends it might be easier and safer now to use DropBox than uploading you’re file through a web interface with services like FileDropper, Drop.io or YouSendIt. Just don’t forget to delete a file once everyone got it, because it will be automatically downloaded to your other machines when they get online.

The process of sharing a file in SugarSync is not as smooth. Once you select a file in SugarSync Manager and click the big Send File button on the toolbar, you are taken to the web interface, in a new browser window. Here you need to specify the email addresses where you want the file to be sent. You can import your contacts from you Yahoo/Gmail/Hotmail/AOL account in the SugarSync Adress Book. Unfortunately you can’t get just the link to quickly send it by IM.
Photo Gallery
If you wanted to quickly and painlessly share an image gallery with friends, colleagues or family from a Mac you had three options : export the gallery from iPhoto to Picasa Web Albums or Flickr (with the help of plugins) or publish it to your .ME account. Now there is an even faster way!
In the DropBox folder you have a folder called Photos. When you drop a folder with images in here a web gallery will be automatically created. You follow the same steps as in sharing a file to get the public link to the gallery. The gallery is very basic, with maximum 16 thumnails per page. When you click a photo thumbnail you will be presented with a scaled down to 640 by 480 version.

In SugarSync any synced folder that contains images will automatically have it’s own web photo album. To see this albums click Go to Photo Gallery button which will take you to the web interface.
The photo gallery is more advanced. You can choose between slide show, small/large thumbnail view or mosaic view (when you click a photo in thumbnail view). To share an album you have to to go through the obnoxious process of clicking the Share Album link and then selecting the emails where you want the gallery link to be sent. One thing to notice: after sharing the gallery with someone by email, you can now directly copy and send the gallery’s link in your browser’s address bar to your IM friends.

File Versioning
Both applications are similar to TimeMachine in Leopard. They store previous versions of all your files, so you can easily restore them at a later time.
After initial synchronization, every time you modify a file in DropBox, only the changes will be uploaded in the cloud, not the whole file. In the DropBox submenu click Versions to see all the revisions you made to that file.

SugarSync works in a similar manner, but it only stores the last five versions. Luckily, only the most recent version of each of your files counts towards your storage quota.

File Collaboration
One important feature that SugarSync lacks is collaboration. In DropBox you can create special folders you can share with other DropBox users. Any member of a shared folder can add, edit and delete the contents within and changes will be instantly synced to all members. So if you don’t fancy Google Docs and rather work on your offline document editor together with a colleague now you can!
Size and Price
DropBox offers a free plan with 2 GB storage and $99 a year or $9.99 a month with 50 GB.
SugarSync has no free plans but at least you can choose a 45 days trial with 10 GB space. There are five paid plans:
| Plan name | Monthly | Yearly | Storage |
| Starter | $2.49 | $24.99 | 10 GB |
| Basic | $4.99 | $49.99 | 30 GB |
| Premium | $9.99 | $99.99 | 60 GB |
| Professional | $14.99 | $149.99 | 100 GB |
| Basic | $24.99 | $240.99 | 250 GB |
Conclusion
There is no clear winner in this fight. They both do the job extremely well. SugarSync may have more features (like iPhone sync) , but the free 2 GB plan, Linux support and the unbelievably ease of use of DropBox, makes it more appealing for many (including me).
And if you wish DropBox had backup features for any folder on your disk, like SugarSync , instead of waiting for the implementation you might want to take a look at Mozy’s free 2 GB plan. But that’s the subject of another article!

I’m sticking with Dropbox, it seems much better still.
A note to the readers – I don’t know if someone is doing this on purpose but submitting my articles to digg using absolutely hideous titles and descriptions is not helping me at all – and in fact it ruins the domain’s karma. So, please, if you don’t want to bother writing a proper description just don’t submit it.
I’ve been using dropbox for a while now and its great, the only extra feature I’d want from it is maybe an “on demand” option where files are only downloaded when requested or a “not to this computer” option so I can select certain files to show up on most computers but not have them try to download to my tiny 4Gb AspireOne.
SugarSync is by far a more complete product. If you only want to share a few folders in a FIXED location for free Dropbox it’s probably OK. Do not use it if you have serious documents because it’s not reliable. If you want to be able to backup and access ANY folder, backup any data online, access the data from mobile web browsers, iPhone/Blackberry/WinMo mobile devices, and stream your music files to the Web and iPhone etc. then SugarSync is the only option.
I agree with P. Andrade.
Dropbox DOES have a speed + ETA (at lest in Windows). Just right click the tray icon, or whatever the equivalent of doing that in the Mac version is.
I don't understand why you say that DropBox is not suitable for backup.
If you move the files that you would like to be kept safe into your DropBox then they are backed up to the cloud. They can be accessed from any computer using the web interface, or if your hard drive dies from your new computer by installing and signing into DropBox. I think you have slightly misunderstood the product to be honest.
I'm personally refer to DropBox, for my Mac and Windows also
Cool stuff, thank you for sharing.
You can actually backup/synchronise any folder on your disk with Dropbox. Just make a link to the folder you want to backup and put the link in your Dropbox folder.
In Nautilus on linux this would be: Right-click the folder and choose Make link. Then move the link to your Dropbox folder and rename to whatever you like.
Thanks for the write up and while maybe dated compared to this comment still holds truth.
I really like Dropbox and hope they don't take a turn int "sharing" and "social" realms as before you know it people want to link it to every other possible social-ego-centric app such as facebook, flickers etc…and hello bloatware and increase in pricing.
I wonder if you have reconsidered Windows Live Share as it has mac support now?
Thanks!
