There are some Drush commands available for Views, initially added in Drush command to revert views:

• views-dev (vd) - Setup the views settings to a more developer oriented value
• views-revert (vr) - Revert overridden views to their default state. Make backups first!

Examples:
drush views-revert
[prompts the user with a list of overridden views to choose from, or to revert all]

drush views-revert archive myview2
[reverts the two specified views]
