      Description

      There are test failures that are difficult to investigate without having access to the generated data files (e.g. backup_restore.js, wt_unclean_shutdown.js). We should consider either (a) adding support for tasks defined in etc/evergreen.yml to upload data files to S3, or (b) defining a new task in etc/evergreen.yml that runs these specific tests.

      If we decide to add support for archiving data files in Evergreen without changing the resmoke.py suite definitions (option "a"), then we'll need a mechanism to upload data files immediately after any test failure. This may require the changes from EVG-694 to execute the s3.put command in a resmoke.py after_test hook. (It is unlikely we could get away with moving the data files to a separate directory and uploading all of them at end of the suite without potentially filling up the disks on our EC2 machines.) If we decide to define a new task for archiving data files in Evergreen (option "b"), then we could simply run it with using continue_on_failure=false.

      Note: The archiving of the FTDC data is currently flawed, as only the FTDC data from the mongod processes in the last test (not necessarily even a failure) is uploaded to S3.
