Know where data lives
Document the database, filestore, external services and repositories involved. A dashboard being available does not by itself prove that data is recoverable.
Use roles and least privilege
Grant access from business responsibilities, test with ordinary users and review inactive or excessive permissions. Keep an emergency administrator under a controlled procedure.
Export in useful formats
Plan how contacts, products, documents and accounting evidence can be retrieved. Preserve stable identifiers and explain relationships needed to rebuild context.
Test backups by restoring
A scheduled backup is only a claim until a restore succeeds. Record the date, scope, checksum, retention, encryption and observed restoration result.
Keep a change trail
Version code and configuration, document production decisions and separate tested, deployed and operational states. This makes maintenance and future migration safer.
