It isn't practical on really big jobs because they take so long to save, or Teamworked jobs because of data bureaucracy, but my practice is to make a hard backup every hour or after a major project alteration..
This has several benefits:
- the power hasn't been the greatest this year - some protection against a total loss.
-- ability to quickly revert to a prior version
-- error protection - like inadvertent SAVE/NOT SAVE situations.
