Planned Failover is a customer-managed failover that
provides the ability to failover your geo-redundant storage account while
keeping geo-redundancy and data durability. You can seamlessly swap the
primary and secondary storage endpoints of your geo-redundant
account. After the Planned Failover is completed, all new
write operations will be directed to the original secondary region,
which will serve as the new primary region. Planned Failover can be
utilized in a variety of scenarios including disaster recovery drills,
partial outages where storage remains healthy or proactive disaster
preparation. It is now generally available for GPv2 storage accounts and
is compatible with Blob, ADLS Gen2, Table, File, and Queue data.
