Backing up before the drive fails
Monitoring tells you when risk rises; backups decide whether that risk ruins your month.
The 3-2-1 baseline
Keep three copies of important data, on two media types, with one off-site or offline to survive ransomware and lightning strikes. Monitoring slots into the “when to refresh backups weekly instead of monthly” decision—not replace offline rotation.
Verify restores
A dedupe archive nobody has ever restored is faith-based computing. Quarterly spot-checks prove filesystem integrity—especially after SMART warnings appear.
Clone vs image
When sectors remap aggressively, clone boot drives block-for-block to fresh hardware before running destructive diagnostics on the failing unit.
