Backups, immutability and restoration
Designing backups that survive a compromised administrator
Backup has become the last line of defence again, now that ransomware explicitly targets recovery arrangements. This course covers the 3-2-1-1-0 rule, isolation from the administration domain, and honest measurement of restoration time.

Choosing a restoration point, measuring duration, and catching up lost data.
Assessment method
Self-check questions throughout the lessons, with no recorded score. Where an associated track leads to a certification, that certification has a separate exam.
Document issued
This course does not, on its own, lead to a certificate. A track certification, where one exists, is issued after its exam is passed.
