Does anyone know of some good Mac software to sync a network attached storage device or a drobo to Amazon S3?

I'd love to mail them a storage device for the first dump and then do nightly syncs.

What about Jungle Disk?

It will set up an s3 account as a local drive. I'm not sure what sync capabilities it has natively, but your mac has rsync built-in and you could use that.

There's more discussion about other Amazon s3 clients in the question about the best Amazon s3 file manager utility.

I'll check it out and see, thanks – mjr Sep 2 '09 at 21:47
At least on Linux and Windows, JungleDisk offers a very capable backup (automated) option with versioning. It also offers a sync capability that I have not used (I do use the old style backup option, but not their newer one). The sync looks to be similar to Dropbox, although possible not as smoothly integrated. – ydant Oct 1 '10 at 22:22
Jungle Disk is good, but since it's been bought by rackspace, it automatically sets your backup to go to the rackspace cloud. I think you can configure it to use S3 still though. – seanyboy Oct 18 '10 at 9:09

As a side note:

I'd love to mail them a storage device for the first dump

And you're also prepared to use such service when you need to restore your whole system?

If not, then you may want to consider if an online backup really suits your needs, and see some generic thoughts on some test results at Best choice for a personal “online backup” in Europe. (Restoring a full system may take days or weeks, and may not be as complete as expected.)

I have some local backups running as well, but I wanted something in a complete different location, and I've already been using S3 for a couple things – mjr Sep 2 '09 at 21:39

You can try using s3sync, a Ruby app. This article mentions a number of options, and opines that Cyberduck is the best of the lot for Macs.


There is another option to backup data to cloud storage powered by Amazon S3. Check out CloudBerry Backup . It is one time fee and the rest what you pay for Amazon S3

Arq is an online backup tool for Mac, which uses Amazon S3 as backup storage.

Arq stores the backup data in your own Amazon S3 account, encrypted with your own password using AES-256. Backups are stored in an open format documented on the website.
