Daily EBS snapshots must be created automatically at midnight and deleted after 30 days — no scripts, no manual work. Which service manages this lifecycle?
A.AWS Backup only
Backup works too, but 'EBS-native lifecycle' = DLM — the narrower purpose-built tool.
B.Amazon Data Lifecycle Manager (DLM)
DLM = snapshot/AMI lifecycle policies. Correct.
C.EventBridge + Lambda snapshot script
Custom automation duplicates a managed feature.
D.EBS fast snapshot restore
FSR speeds restore from snapshot — doesn't create them.
Why this answer
DLM automates EBS snapshot/AMI creation and retention via tag-based policies — 'snapshots daily, keep 30 days' is its exact purpose. AWS Backup also works but DLM is the EBS-native answer; FSR accelerates restore, doesn't schedule.
