Serverless solution for continuous data protection

A system comprising:

• a processor;
• and memory configured to store one or more sequences of instructions which, when executed by the processor, cause the processor to carry out the steps of:
• providing a serverless application to a cloud site of a cloud services provider, the cloud services provider offering backend services comprising an object store and a database;
• intercepting a plurality of input/output (IOs) written to a volume of a block storage device at a production site, remote from the cloud site;
• aggregating, at the production site, the plurality of IOs for storage in an object at the object store of the cloud services provider;
• and
• transmitting, from the production site to the cloud site, the aggregated plurality of IOs and metadata associated with each IO, the metadata for each IO comprising a write timestamp indicating when an IO was written, a write offset of the IO, and a write size of the IO,
• wherein upon receipt of the aggregated IOs and metadata at the cloud site, the aggregated IOs are stored in a single object in the object store at the cloud site, and a function of the serverless application is triggered that writes the metadata to the database offered by the cloud services provider.

A computer program product, comprising a non-transitory computer-readable medium having a computer-readable program code embodied therein, the computer-readable program code adapted to be executed by one or more processors to implement a method comprising:

• providing a serverless application to a cloud site of a cloud services provider, the cloud services provider offering backend services comprising an object store and a database;
• intercepting a plurality of input/output (IOs) written to a volume of a block storage device at a production site, remote from the cloud site;
• aggregating, at the production site, the plurality of IOs for storage in an object at the object store of the cloud services provider;
• and
• transmitting, from the production site to the cloud site, the aggregated plurality of IOs and metadata associated with each IO, the metadata for each IO comprising a write timestamp indicating when an IO was written, a write offset of the IO, and a write size of the IO,
• wherein upon receipt of the aggregated IOs and metadata at the cloud site, the aggregated IOs are stored in a single object in the object store at the cloud site, and a function of the serverless application is triggered that writes the metadata to the database offered by the cloud services provider.
