How To Do Things
================
----------------

Process Runs
------------
~~~~~~~~~~~~

Remove Runs
~~~~~~~~~~~
^^^^^^^^^^^

From the dashboard click on the button (PASS/FAIL...) for one of the tests. From the test control panel that 
comes up push the clean test button. The command field will be prefilled with a template command for removing 
that test. You can edit the command, for example change the argument to -testpatt to "%" to remove all tests.

.Remove the test diskperf and all it's items
----------------
megatest -remove-runs -target ubuntu/nfs/none -runname ww28.1a -testpatt diskperf/% -v
----------------

.Remove all tests for all runs and all targets
----------------
megatest -remove-runs -target %/%/% -runname % -testpatt % -v
----------------

Archive Runs
~~~~~~~~~~~~
^^^^^^^^^^^^

Megatest supports using the bup backup tool (https://bup.github.io/) to archive your tests for efficient storage
and retrieval. Archived data can be rapidly retrieved if needed. The metadata for the run (PASS/FAIL status, run 
durations, time stamps etc.) are all preserved in the megatest database.

For setup information see the Archiving topic in the reference section of this manual.

To Archive
^^^^^^^^^^
++++++++++

Hint: use the test control panel to create a template command by pushing the "Archive Tests" button.

.Archive a full run
----------------
megatest -target ubuntu/nfs/none -runname ww28.1a -archive save-remove -testpatt %
----------------

To Restore
^^^^^^^^^^
++++++++++

.Retrieve a single test
----------------
megatest -target ubuntu/nfs/none -runname ww28.1a -archive restore -testpatt diskperf/%
----------------

Hint: You can browse the archive using bup commands directly.
