US 2025/0053481 A1 · HYBRID DATA TRANSFER MODEL FOR VIRTUAL MACHINE BACKUP AND RECOVERY

Abstract

A storage cluster may dynamically select a data transport mode for supporting a backup or export job. The storage cluster may receive a trigger indication to create, a backup of data of a source virtual machine. The storage cluster may select a data transport mode to use for reading the data from the source virtual machine to create the backup at the storage cluster. The selection may be from a set of data transport modes that includes a proxy virtual machine mode and a direct-to-host mode. The storage cluster may transmit, to a host for the source virtual machine, a request to activate the selected data transport mode, and receive the data from the source virtual machine via the selected data transport mode. The storage cluster may use the data to create the backup.

Dependent claims

A method, comprising:

identifying a trigger for creation of a backup of data of a source virtual machine, wherein creation of the backup comprises use of a proxy virtual machine mode to read the data from the source virtual machine;
calculating, to support the use of the proxy virtual machine mode for creation of the backup, a quantity of proxy virtual machines to use to read the data from the source virtual machine in accordance with the proxy virtual machine mode, wherein the quantity of proxy virtual machines is based at least in part on a total size of one or more virtual disks of the source virtual machine and a maximum quantity of child jobs per proxy virtual machine;
transmitting, to the source virtual machine, a request to activate the quantity of proxy virtual machines;
and
receiving, based at least in part on transmitting the request, the data from the source virtual machine via the quantity of proxy virtual machines.

2 more elements

An apparatus, comprising:

one or more memories storing processor-executable code;
and
one or more processors coupled with the one or more memories and individually or collectively operable to execute the code to cause the apparatus to:
identify a trigger for creation of a backup of data of a source virtual machine, wherein creation of the backup comprises use of a proxy virtual machine mode to read the data from the source virtual machine;
calculate, to support the use of the proxy virtual machine mode for creation of the backup, a quantity of proxy virtual machines to use to read the data from the source virtual machine in accordance with the proxy virtual machine mode, wherein the quantity of proxy virtual machines is based at least in part on a total size of one or more virtual disks of the source virtual machine and a maximum quantity of child jobs per proxy virtual machine;
transmit, to the source virtual machine, a request to activate the quantity of proxy virtual machines;
and
receive, based at least in part on transmitting the request, the data from the source virtual machine via the quantity of proxy virtual machines.

5 more elements

A non-transitory computer-readable medium storing code, the code comprising instructions executable by one or more processors to:

identify a trigger for creation of a backup of data of a source virtual machine, wherein creation of the backup comprises use of a proxy virtual machine mode to read the data from the source virtual machine;
calculate, to support the use of the proxy virtual machine mode for creation of the backup, a quantity of proxy virtual machines to use to read the data from the source virtual machine in accordance with the proxy virtual machine mode, wherein the quantity of proxy virtual machines is based at least in part on a total size of one or more virtual disks of the source virtual machine and a maximum quantity of child jobs per proxy virtual machine;
transmit, to the source virtual machine, a request to activate the quantity of proxy virtual machines;
and
receive, based at least in part on transmitting the request, the data from the source virtual machine via the quantity of proxy virtual machines.
