Based on your hardware, the ERDA component analyzes which files you access most frequently within the archive and decompresses those into a high-speed system cache before you even click them, making browsing large archives feel like a local SSD folder.
The standout feature for could be Temporal Differential Recovery .
Instead of just compressing static data, this feature allows the archive to act as a "living" snapshot. If you update the files inside the archive and save it again, it doesn't overwrite the old version; it stores only the binary-level differences (deltas) in a hidden sub-layer.
