US 12,613,784 B2 · Lossless failover for data recovery

Abstract

Some users of a data management system (DMS) may use multiple computing environments to replicate and store virtual machines (VM)s, such as for backup and recovery purposes. For example, different replication environments may include one or more private data centers, one or more cloud environments or any combination thereof. A user may schedule a failover procedure for an application. A DMS may perform a failover procedure that reduces downtime and eliminates data loss. The DMS may capture and replicate a snapshot of a VM running on a source computing environment to a target computing environment, power down the VM on the source computing environment, capture and replicate a second snapshot of the VM to the target computing environment, and power on the VM at the target computing environment. As the additional snapshot includes a relatively small amount of data replication at the target computing environment may proceed quickly, reducing downtime.

Dependent claims

A method, comprising:

determining, by a data management system, a set of latencies associated with a failover procedure of a virtual machine from a first computing environment, the set of latencies comprising latencies associated with different starting times for the failover procedure, latencies associated with different computing environments of a plurality of computing environments, or any combination thereof;
replicating, by the data management system, one or more snapshots of the virtual machine to a second computing environment of the plurality of computing environments, wherein a starting time of the replicating, the replicating being to the second computing environment, or a combination thereof is based at least in part on the set of latencies;
and
powering on the virtual machine at the second computing environment based at least in part on the one or more snapshots.

1 more element

An apparatus, comprising:

at least one processor;
memory coupled with the at least one processor;
and
instructions stored in the memory and executable by the at least one processor to cause the apparatus to:
determine, by a data management system, a set of latencies associated with a failover procedure of a virtual machine from a first computing environment, the set of latencies comprising latencies associated with different starting times for the failover procedure, latencies associated with different computing environments of a plurality of computing environments, or any combination thereof;
replicate, by the data management system, one or more snapshots of the virtual machine to a second computing environment of the plurality of computing environments, wherein a starting time of the replicating, the replicating being to the second computing environment, or a combination thereof is based at least in part on the set of latencies;
and
power on the virtual machine at the second computing environment based at least in part on the one or more snapshots.
