Azure Archive Storage provides a secure, low-cost means for retaining cold data, including backups and archival storage. Data stored in Archive Storage is offline and unavailable for read access until it is rehydrated to the hot or cool tier. You can choose to rehydrate data with standard or high priority, depending on the urgency of the retrieval request. Previously, it was not possible to change the retrieval priority after initiating a rehydration operation; priority had to be determined in advance, and there was no flexibility to update the priority if the retrieval urgency subsequently changed.
Archive Storage now supports updating the retrieval priority from standard to high while a rehydration operation is pending. You can simplify rehydration management and improve cost efficiency by initiating the rehydration operation with standard priority for a set of blobs, then updating the priority to high for any blobs that require faster retrieval.
