Azure blob archive rehydration

Question

Does there is any estimation when rehydration is in process from 75 GB to 100 GB in standard priority

Will there be any performance impact using copy blob or set blob tier

@Deepu Welcome to Microsoft Q&A Forum, Thank you for posting your query here!

• The general guidance is to rehydrate the first batch of 10 GB within 15 hours with standard priority retrieval and 1 hour with high priority retrieval. See Rehydrate an archived blob to an online tier - Azure Storage | Microsoft Docs. For the rest of data, the retrieval speed is 60 MBps to 100 MBps. Daily retrieval speed would be 5 TiB to 8 TiB. However, there are many factors that may affect rehydration performance, including file size distribution, how files are archived over past time windows, etc. It would be great to get more details about these factors for reasonable estimation.
• Set Blob Tier changes the tier for rehydration in place while copy blob involves both copy and rehydration. However, it doesn’t make big difference in the order of rehydration time.
