v6.35 (Windows) adds support for Rackspace Cloud Files

Syncovery for Windows now supports synchronizing your files with Rackspace Cloud Files. This is the first of a series of new cloud services that will be supported in the near future.

Cloud storage allows you to upload as much data as you need, paying only for the storage that you are actually using. It is a highly recommended storage location for your online backups. You need to sign up with the cloud storage provider, and then set up a profile to upload your data. Choose your local folders on the left-hand side, and click on the Internet button for the right-hand side. Then, choose the protocol you want to use (for example: Rackspace), and specify a container and folder where the data should be stored. You should also specify your Rackspace username and password (access key) here.

Even though your data is uploaded via secure https with SSL, you may want to use zipping and encryption for your files. To keep a constantly updated mirror of your data, we recommend using the option “Zip Each File Individually”.

Due to the nature of Rackspace Cloud Files, the “Last Modified” timestamp of your documents cannot be preserved. Therefore, we recomend to use the “Filename Encoding” feature of Syncovery. This adds the timestamps to the file names when uploading, and restores the original names and timestamps when restoring. You will find this checkmark on the Versioning tab sheet, as well as on the Internet dialog.

Additional cloud services will be added in the near future. Feel free to send your suggestions to info@syncovery.com!

Amazon Glacier Backup

Since version 6.20, Syncovery can upload files to Amazon Glacier. To set up Glacier as the destination, click on the Internet button for the right-hand side and choose Glacier as the Internet Protocol.

Amazon Glacier is intended for long term archiving and backup with the expectation that most operations are uploads and not downloads. Downloads should be a rare exception, since they can be extremely slow. To download a file, Syncovery needs to initiate a job with Amazon Glacier, and even with small files, it takes at least three hours for Amazon Glacier to retrieve the item. The same is true for file listings. Therefore, Glacier cannot be used for two-way synchronizations. It is intended only for backing up and archiving.

Please be aware that there is a download fee from Amazon if you download more than 5% of your data per month (or something like that). It seems that in some special cases, the download fee can be extreme. If you intend to make a full backup and restore for testing, please read the fee schedule closely, and also read articles such as this one:
Is There a Landmine Hidden in Amazon’s Glacier?


Two methods to use Glacier

  • Choose S3 inside our software, and use a lifecycle rule in S3 to move files to Glacier to reduce costs. See the Amazon Web Services Blog
  • Choose Glacier directly in our software. The rest of this article describes this method.

Because there is no quick way to get a file listing from Glacier, Syncovery maintains a local database with the information of all the files on Glacier. This database is automatically maintained and it is independent from the checkmark “Cache Destination File List”. Therefore, with Glacier, there is no need to use the caching option. The local databases used for Glacier are separate for each vault, but shared among all profiles. When you create a new profile that accesses an existing vault, it will alraedy know the vault contents, if the vault has been used on the same machine.

Glacier also cannot rename items which have been uploaded. When you rename or move files on the local side, they have to be uploaded again.

In version 6.20, the download process is still inefficient if you need to download many files. It will initiate the download job for each file and wait for it to complete, then download the file, and then proceed to the next file. You can specify a number of files to copy in parallel in this fashion (on the Files tab sheet), but the limit is 30. So, you can download up to 30 files in 3 to 5 hours, but downloading 300 files will take 30 to 50 hours. This limitation will be removed in a future update.

In light of this, if there is a chance you will need a complete restore, it may make sense to use “Zip Packages” with many files per zip archive, instead of uploading individual files.

This information will be updated as support for Glacier is optimized and more experiences are made with Amazon’s new service.

Mountain Lion Compatibility

A Mountain Lion compatible update of Syncovery is now available. The version number must be 6.03 or higher.

To be able to continue using your old configuration and profiles, please use at least version 6.04 or higher.

The migration wizard should appear automatically, or you can invoke it via the File menu. You can also manually import config files via the File menu.

Since version 6.04, no special action is required any more to migrate your settings.

Syncovery 6 has been released

Version 6 has been released in mid-2012, under the new name Syncovery! After one year of development, we are confident that the improvements will be great to have for all our users and customers. Version 6 uses new registration codes and you can order your license or upgrade from Super Flexible File Synchronizer. Many customers will receive a free upgrade, if their license purchase was within the past two years.

The list of new features can be seen here.

If you wish to upgrade, please install Syncovery on top of your current version and it will show the migration wizard.

For those customers who are using the ExtremeSync Remote Service, please note that you need to replace it with the new Syncovery Remote Service and update all clients and servers at once, unless you want to keep both Remote Services running during the transition period.

Everybody can now upload “any file” to Google Docs!

Apparently Google has removed a limitation and it is now possible for all Google customers to upload “any file” to Google Docs. If you would like to try it, make sure you have the latest software version from our web site.

Up until at least mid-2011, our Synchronizer could only upload converted files unless the customer had a Google Apps Premier account. Now this problem is completely gone.

That is really great news I think!

Syncovery is the new name for Super Flexible File Synchronizer


After over eight years of successfully fulfilling our customers’ needs, the application finally deserves a new name. We feel that the new name Syncovery is a great improvement due to its shortness, and it is actually a name rather than just a long description. You can say that Syncovery is a super flexible file synchronizer.

Along with the new name, various file names, folder names, and service names used by the application are all being unified. Rather than having an ExtremeSync Service, we now have a Syncovery Service.

In addition, the folder where the program stores its private data and logs is now named Syncovery. So problems with some folders having spaces (Super Flexible) and others not (SuperFlexible) are a thing of the past, too.

Finally, we are also launching this new web site. Due to its content management system, it will be much easier to update it regularly and post as many new articles and FAQs as possible. We intend to provide our customers with a wealth of information, which will also make it easier for new prospective customers to get a clear picture of what Syncovery can do prior to downloading it.
