Deleting blobs is safer than removing the container, which might break Backup Vault references if it relies on an internal ID.

Use AzCopy to efficiently delete all blobs while keeping the Backup Vault association intact. Deleting the container itself may break Backup Vault references, so it's safer to remove only the blobs unless you are sure backups won’t be affected.

I have some blobs in the container.

I had used the azcopy command below to delete the blobs from the container.

azcopy rm "https://<StorageName>.blob.core.windows.net/<ContinerName>?<SASToken>" --recursive=true

Blobs were deleted successfully.
