Minor Release: Aspera Sync 3.8.1 for Linux, Mac OS X, and Windows

Product Release: July 3, 2018

We are pleased to announce the release of IBM Aspera Sync 3.8.1 for Linux, Mac OS X and Windows. This release offers two new sync option settings.



  • A new async option, --ignore-mode, prevents the file mode from being synced from the source to the destination. Use this option to allow the file to have different modes on the source and destination and to prevent Sync from hanging if the destination permissions change.
  • Sync now respects the files_filelock_enabled setting in a user's access key, which overrides the server setting in aspera.conf.
  • A new Sync option --clean-excluded can be used to optimize the Sync snapshot database when using --exclude-dirs-older-than or --exclude by removing directories from the snapshot as they become excluded. The option applies to all Sync directions and the excluded paths are removed from the snapshot database on both endpoints.



This 3.8.1 release is available for download for each individual product listed below. Aspera’s support team stands by ready to help you as needed with upgrades. If you have any questions or would like upgrade assistance, please contact aspera-support@ibm.com.
