      I guess the answer is premium because of this:

      – In the event of a restore, data must be recovered by using the fastest available method.

      Premium storage account would have a higher IOPS so the recovery method is faster than using a Standard storage account.

    Ok, I’ve been digging about this and this is what I got:

    First of all, these answers are either kind of wrong or they’re trying to confuse us with a couple terms:

    In Azure SQL databases there’s no “Storage Tier” or “Storage Method” option. We have “Service Tier”, automated backups and optional replications

    *In Service Tier every tier has an automated backup solution integrated (This is what makes Point-In-Time restore possible) but the retention days for the Point-In-Time restore depends on the tier selected.

    Basic – 7 Days
    Standard – 35 Days
    Premium – 35 Days

    *The optional replication is what makes the secondary copies on the same or different datacenters but the only one that synchronize 4 secondary copies is Active Geo-Replication.

    *The Estimated Restore Time for AGR will depend on the tier that we selected:

    Basic – Not Applicable in this case because of the retention days.
    Standard – ERT < 30s
    Premium – ERT < 30s

    So with Active Geo Replication and Standard or Premium Tier we cover these requirements:

    – You must be able to restore the database to any point in time for the last 30 days.

    – In the event of a restore, data must be recovered by using the fastest available method.

    – SQL backups must be stored in up four secondary regions.

    So the only requirement left is Minimize Costs:

    The higher Standard tier option cost – 150.00/Month
    The lowest Premium tier option cost – 465.00/Month

    So Standard tier and Active Geo-Replication

      Thanks Starlin.

      It looks like “Standard” geo-replication has been deprecated and Active is now the only available option for all service tiers.

      Some more details on Active geo-replication.
