US Signal Disaster Recovery Gets a Boost from Zerto

US Signal DRaaS with Zerto


There was a lot of excitement last year at VMWorld in Las Vegas when Zerto announced the latest version of its disaster recovery software, Zerto Virtual Replication (ZVR) 5.0. One of the reasons — it offers the first hypervisor-based “one-to-many” replication for protecting multiple workloads across different data center sites. With US Signal recently upgrading to the new software to power its Disaster Recovery as a Service (DRaaS) service, that capability can now benefit US Signal customers and prospects alike.

One-to-Many Replication

One-to-many replication is a big deal because it protects virtual machines (VMs) in multiple virtual protection groups (VPGs), each with its own service level agreement (SLA) and the option to replicate the VPG to a different target platform. Before the introduction of this feature, a VM could only exist in one VPG at once.

Without this limitation, VMs can be replicated to each target simultaneously in multiple VPGs. Each can have recovery point objectives (RPOs) in seconds but without the performance impact of snapshots. This means that multi-site can also be used for protecting an entire site to a DR site, while also protecting individual application stacks locally.

VPGs can also have different journal data retention policies configured for point-in-time recovery. The journal contains the compressed block-level changes for the history configured to enable recovery to thousands of points in time, between one hour and 30 days. There are additional settings for maximum size, warning thresholds, and the ability to store the thin journal vDisk on a separate datastore to the replica VM for maximum flexibility.

As a result, you can have local replicas on separate local storage with 30-day journals for local file and VM restores. At the same time, you can have a remote replica and three-day journal for disaster recovery. All are continuously updated with the block-level changes to just seconds out of date from the production data. Simply re-purpose the existing disk storage used for short-term backups as VMFS (SAN-based block storage) and NFS (NAS-based file storage) datastores; no more nightly snapshot-based backups.  

One-to-Many Replication and US Signal

What does this all mean for US Signal customers and prospects?

If you’re an existing US Signal customer — but don’t have US Signal’s DRaaS — and have Zerto on-premise, you can now replicate to the US Signal cloud without incurring the additional CapEx fees typically associated with standing up a tertiary Zerto site. Paired with private connectivity, your replication traffic never must touch the public Internet.

If you’re not a US Signal customer but you have Zerto, you can add a tertiary site to your protection plan. Consider these possible use cases:

  • If you are protecting local-to-local today, there is the advantage of having an offsite replica in the trusted US Signal cloud.
  • If you are going from local to another remote office and want a third site, there is the benefit of not having to maintain the replica resources at that third site. It’s basically the same story as our cloud. Spin up what you need when you need it, and stop worrying about power, cooling, and keeping hardware current.

And, for customers and prospects that don’t currently have Zerto or US Signal’s DRaaS service, embracing both enables numerous use cases, including:

  • Recovering files and VMs directly to production or a recovery site
  • Protecting VMs to new datacenters during migrations
  • Using the cloud for longer retention and DR
  • Protecting individual VMs locally to recover one VM from a remote multi-VM VPG
  • Protecting multiple application in one consistency group to a remote site for app boot ordering
