A city records bureau needs nightly incremental sync from an on-premises NAS into Amazon S3 with scheduling, encryption, and transfer metrics instead of a hand-built rsync on a jump box. Which service should they choose?
Select an answer to reveal the explanation.
Short Explanation
Homegrown rsync on a jump box is the duct-tape version of a moving company. DataSync is the managed nightly sync that schedules, encrypts, and reports without you babysitting scripts.
Full Explanation
AWS DataSync is the managed service for recurring file-system and NAS synchronization to S3 (and other AWS storage) with built-in scheduling, encryption, and observability. DIY rsync, message brokers, Glue crawlers, and CloudFront invalidations are not the appropriate primary copy engines for this NAS-to-S3 nightly pattern.
