S3 Backup beta 17 rev.1422

Some changes in this release:

  • Reduce the passes over data to a minimum. The data needs to be hashed for future change detection, compressed, encrypted and resulting stream hashed again to ensure its integrity in transfer. All of this is done as efficiently as possible with minimal I/O by doing multiple operations during the same pass.
  • Support for international bucket names: accented, Cyrillic and most other characters. This is accomplished by IDNA encoding
  • New encoding / decoding layer
  • Better upload reporting taking into account things like size changes due to compression and retries in estimating the time remaining.
  • Improved connection pooling.
  • Support for transforming proxies (specifically Transfer-Encoding: chunked)
  • Support for non-alphanumeric characters in backup job names.
  • There was an issue for a couple revisions that was causing buckets with capital letters in their names to be inaccessible, this was fixed soon after it was discovered
  • Backup code sometimes was causing remote directories to be repeatedly recreated. This was fixed.
  • New menu code (important step in porting the app to new GUI backend code, but not a visible change).

Beta 17 was done quite some time ago, but we decided against releasing it on holidays to make sure that if any issues crop up, we would be able to put any time necessary to fix it immediately.

So even while we release beta 17 only now, beta 18 well underway already. The changes coming there will be related to the core backup algorithm that should make it yet faster especially for backup sets with huge amount of small files. Currently known issues:

  • If you cancel an operation during the planning phase it will pop up a debug log with a traceback. It’s just a small UI glitch we’ll correct in one of the nearest releases.

If you come across any other issues, please let us know and we’ll do our best to fix it ASAP.

This is release is part of our runup to a 1.0 release which gives you an opportunity to order it at a discount.
