The ARX can see ________ when a data modification takes place and will cue that file to be migrated back to the primary tier.

ARX intercepts file I/O operations in real time as they traverse the network path, detecting the exact moment a modification occurs on a file residing on a lower-cost tier and immediately scheduling that file for migration back to primary storage - ensuring tiering policies are enforced with zero polling delay and full transparency to clients.

Nightly detection would introduce up to 24 hours of latency between a file modification and its migration back to the primary tier, leaving recently modified files on the wrong storage tier and degrading performance.

Weekly scanning is far too infrequent for production storage environments and would leave modified files on secondary tiers for days, causing sustained performance degradation for active datasets.

Relying on periodic system scans introduces unpredictable latency and unnecessary resource consumption compared to ARX's event-driven real-time monitoring model.

Administrator-scheduled detection eliminates the automation that defines transparent storage tiering and reintroduces manual overhead that ARX is specifically designed to remove.
