03/21/2012Customer Portal Status
Note: existing customers should not be affected.
Update March 25th: all services were migrated and should be fully functional. Please report any issues you see.
There’s currently an issue with our customer portal that prevents new customers from binding their machines to their accounts and sometimes for new customers to get an account at all. The issue is caused by memcache service on Google App Engine which is used for some data locking in the portal.
We will be migrating off GAE this week, but to restore the ability for people to try the app right now, the licensing service will be temporarily switched to “allow all” mode. This means that the licensing service will always return a full-featured license without any checks at all, for everybody.
When the migrated service is brought back online, that will mean that the customers who have installed the app in the meantime will finally be asked to bind the machine to an account and issue a trial license or use a purchased one.
Hopefully everything will be back to normal before the end of the week.
Sorry about any inconvenience caused.
07/26/2011New Product: CDN Genie
Hello everyone!
We are now developing a new product. We decided to try something new and make its development mostly customer-driven, so we want you to get involved as soon as possible.
The new app is called CDN Genie and its sole purpose is to help manage your public content on S3, CloudFront and soon other cloud hosters and CDNs. The app will replace S3 Webmaster which is now deprecated.
If you decide to be among early adopters you will get a unique opportunity to provide input at an early stage of development. If you do, you will also get a free license when the app is released. Contact us to join the private testing group.
We intend to keep the private testing stage nice and short and move on to public releases in a couple weeks.
We are looking forward to your feedback, and remember, just email us for early access to the app.
03/10/2011S3 Backup 1.1 Final
Not a single bug or problem was found in the release candidate and S3 Backup 1.1 is now final. You can read the release notes in the S3 Backup 1.1 RC announcement or go straight to the downloads.
Update: a bug was found with new backup jobs not saving. A fixed release (r3448) is now available for download, if you’re running r3379-r3446, make sure to upgrade.
03/04/2011S3 Backup 1.1 Release Candidate
A new version of S3 Backup is available. There are no known bugs and unless some are discovered by the users we’ll mark it as stable in about a week.
There are a lot of changes in this release, but even more are coming soon. We decided to keep some of the new code disabled for now just to be on the safe side. If things go as planned and the 1.1 stable is out in a week, we’ll follow it up with further updates that we already have prepared.
Filedb updates
S3 Backup determines which files to upload by maintaining a local database of what files were already uploaded. With every file operation this database needs to be updated to be in-sync with the online copy. The database is stored in SQLite and given that every update is a transaction, it causes a couple of disk operations for every uploaded file. If you have a noisy HDD you would hear that as a “click” or, if you upload a lot of small files as a slight “HDD thrashing”.
We’ve changed this part of code to add another layer of in-memory caching, so now the updates are only written out to disk once in five seconds as a single transaction which makes it completely unnoticeable.
This also provides a performance improvement and paves the way for the updates we will reveal in future releases.
New GUI code
In preparation for the Mac and Linux ports we’ve given our GUI code an overhaul. The settings dialog is completely new and even friendlier than before. You can now create new buckets directly from the bucket selection box. Some options were removed as well, so the proxy is now acquired from the system-wide configuration and S3 connections are always SSL-encrypted.
Bucket Manager was also rewritten and among other things allows concurrent operations (listing or deleting any number of buckets at the same time). It is accessible from the menu Tools → Bucket Manager.
Faster backups
In addition to the filedb speedup we’ve determined that logging was sometimes consuming disproportionate amount of resources because of being hooked in with the GUI code. We’ve throttled the GUI updates and made sure there’s no overhead at all when the debug log is not open.
Bugfixes
- There were issues with automatic migration of backups jobs from backups.xml to the new config.json format if the config was password-protected. This was fixed.
- We’ve discovered that PyCrypto 2.0.1 which we used for the most of the app’s lifetime during beta has a bug. When the key length was longer than 192 bits, the cipher was encrypting the stream in such a way that it cannot be decoded with any other Blowfish implementation, including the one from PyCrypto 2.3 that we are using now. We now include the old buggy version of Blowfish cipher and use it when decoding the old streams. (Most users will never encounter this condition anyway).
Other changes
- Support for new Japan AWS region
- New menu item: Tools → View past logs
- Upgraded to Python 2.7
- Massive updates to the build process (this is particularly important for Mac OS X and Linux ports).
- The logging and traceback collection system was updated to be more resilient to various unicode-related issues.
- Other miscellaneous updates

11/13/2010S3 Backup 1.0.5 — Much faster planning
S3 Backup 1.0.5 provides a major speedup for the backup planning process. Before this update, the more files were scheduled for upload the slower the planning process became. The upload itself was sped up as well, but to a lesser degree.
This is a recommended update for everyone who backs up at least couple hundred files. If you have a thousand or more in the backup set, the speedup will be dramatic, so make sure to upgrade.
We have more performance improvements in the pipeline. Stay tuned.
This release also fixes a bug that could cause an error when downloading a lot of files encrypted with different passwords. We found this bug during code review and as far as we know no user has encountered this problem yet.
