Data backup management during workload migration

A computer system for managing data backup, the computer system comprising:

• a bus system;
• a storage device connected to the bus system, wherein the storage device stores program instructions;
• and
• a processor connected to the bus system, wherein the processor executes the program instructions to:
• identify a set of workloads for migration from a source environment to a target environment in response to receiving a request to migrate the set of workloads;
• initiate the migration of the set of workloads from the source environment to the target environment along with migration of the backup data corresponding to the set of workloads;
• determine a backup configuration transformation from a backup configuration corresponding to the source environment to a set of backup configurations corresponding to the target environment based on semantic matching between characteristics of the backup configuration corresponding to the source environment and characteristics of the set of backup configurations corresponding to the target environment, a state of the source environment, backup configuration transformation actions, and a goal state of the target environment, wherein the characteristics include data dependencies between virtual machines executing the set of workloads and wherein the set of workloads is migrated in waves based on the data dependencies;
• analyze the characteristics of the backup configuration corresponding to the source environment for each workload in the set of workloads for the migration to the target environment;
• analyze the characteristics of the set of backup configurations corresponding to the target environment, wherein the backup data migration represents a migration of all backed up data corresponding to the set of workloads being migrated in the set of workloads migration;
• perform the semantic matching between the characteristics of the backup configuration corresponding to the source environment and the characteristics of the set of backup configurations corresponding to the target environment for each backup capability;
• and
• form the backup data corresponding to the set of workloads by performing a data backup for all virtual images in a particular wave before migrating the set of workloads from the source environment to the target environment.

A computer program product for managing data backup, the computer program product comprising a computer readable storage medium having program instructions embodied therewith, the program instructions executable by a computer to cause the computer to perform a method comprising:

• identifying, by the computer, a set of workloads for migration from a source environment to a target environment in response to receiving a request to migrate the set of workloads;
• initiating, by the computer, the migration of the set of workloads from the source environment to the target environment along with migration of backup data corresponding to the set of workloads;
• determining, by the computer, a backup configuration transformation from a backup configuration corresponding to the source environment to a set of backup configurations corresponding to the target environment based on semantic matching between characteristics of the backup configuration corresponding to the source environment and characteristics of the set of backup configurations corresponding to the target environment, a state of the source environment, backup configuration transformation actions, and a goal state of the target environment, wherein the characteristics include data dependencies between virtual machines executing the set of workloads and wherein the set of workloads is migrated in waves based on the data dependencies;
• analyzing, by the computer, the characteristics of the backup configuration corresponding to the source environment for each workload in the set of workloads for the migration to the target environment;
• analyzing, by the computer, the characteristics of the set of backup configurations corresponding to the target environment, wherein the backup data migration represents a migration of all backed up data corresponding to the set of workloads being migrated in the set of workloads migration;
• performing, by the computer, the semantic matching between the characteristics of the backup configuration corresponding to the source environment and the characteristics of the set of backup configurations corresponding to the target environment for each backup capability;
• and
• forming the backup data corresponding to the set of workloads by performing a data backup for all virtual images in a particular wave before migrating the set of workloads from the source environment to the target environment.
