Versioning and recovery of workloads

A method, comprising:

• generating, by a computing device, a volume as a file in memory, wherein the volume is based on an operating system (OS) image;
• attaching the file to a workload;
• booting the workload using the OS image;
• generating a version of the file with a block that underwent change and metadata associated with the change based on an input/output request to the volume;
• storing, by the computing device, the file and the version of the file on a storage device associated with the computing device;
• identifying blocks to be combined in the storage device using a bloom filter and associated metadata;
• and
• recovering a version of the volume associated with the workload using the identified blocks.

A non-transitory machine-readable storage medium having stored thereon machine-readable instructions to cause a computer processor to:

• obtain user input comprising a version of a volume associated with a workload to be reverted and a target device where the version of the volume to be reverted;
• generate an updated file by combining blocks associated with multiple versions in a storage device using a bloom filter based on the user input, wherein the storage device comprising a version store including a content file and multiple versions of the content file associated with the workload, wherein the content file is to preserve a state of a base volume, and wherein a version of the content file is to include a block that underwent a change and metadata associated with the change corresponding to input/output on the base volume;
• and
• recover the version of the volume associated with the workload on the target device using the combined blocks and the metadata.
