Set out below are listed the issues that are known to be problems in the Data Archive.


Known Issue: Multiple versions may be created when overwriting unchanged files on the archive using the Web Interface

If you use the Web application to upload a file in the same location, and the file has not been changed (since it was added to the Data Archive), a new version will be incorrectly created. This new version does not change the content of the file or create a new copy, the new version is identical to the existing version. No action is required on your part. When you download the affected file, downloading either version will produce the same result. This does not affect SFTP, Command line script, or Java applet interfaces.


Known Issue: use ZIP format with file paths longer than 256 characters.

If you use the Download as Archive function and TAR format with file paths longer than 256 characters you may experience a problem where the download finishes early and is not complete. If you encounter this issue, please use the ZIP format option with the Download as Archive function.

Note: EndNote users are particularly vulnerable to this issue (long file names). See here for more information.


Known Issue: use the Web application for less than 50 GB and 1000 files.

The Data Archive Web application is suitable for researchers who wish to search the Data Archive and to either upload or download less than 50 gigabytes (GB) of data and/or less then 1000 files (during a single session). See the Web application guide for more information.

Researchers who frequently upload or download data, and/or generate datasets, may wish to schedule a regular upload or download of data rather than manually uploading and downloading data via the Web application.

  • Researchers who upload or download more than 50 GB of data and/or more than 1000 files, at a time, please see the SFTP client guide.
  • Researchers who wish to schedule a regular upload or download of data, please see the Command line script guide.
