S3 Backup 1.0.2 — Improved Encryption

S3 Backup 1.0.2 is now available for download and provides significant improvements in encryption. This is a recommended update if you have encryption enabled.

  • Stream format was changed to provide improvements in key and encryption strength.
  • An option to use Blowfish cipher was removed. If you have configured S3 Backup to use it, it will be automatically switched to AES-256.
  • An option to use zlib compression was removed. If you have it selected, it will be automatically switched over to bz2 which provides better compression. We are considering providing PPMd compression as well (7-zip) which achieves yet better compression ratios.

Bugfixes

If the backup schedule was configured to run even if no user is logged in, the system environment in such cases sometimes was missing appdata environment key which was preventing the app from running. We now do not depend on that environment value and this issue is resolved.
