Recovering the Metadata of Data Backed Up in Cloud Object Storage

A non-transitory computer readable storage medium having stored thereon program code executable by a computer system, the program code embodying a method comprising:

• creating a snapshot of a data set, the snapshot including a plurality of data blocks of the data set that have been modified since creation of a prior snapshot of the data set;
• uploading the snapshot to a cloud object storage platform of a cloud infrastructure, wherein the snapshot is uploaded as a plurality of log segments conforming to an object format of the cloud object storage platform, and wherein each log segment includes:
• one or more data blocks in the plurality of data blocks;
• and
• a first set of metadata comprising, for each of the one or more data blocks, an identifier of the data set, an identifier of the snapshot, and a logical block address (LBA) of the data block;
• and
• communicating the first set of metadata to a server component running in a cloud compute and block storage platform of the cloud infrastructure.

A computer system comprising:

• a processor;
• and
• a non-transitory computer readable medium having stored thereon program code that, when executed, causes the processor to:
• create a snapshot of a data set, the snapshot including a plurality of data blocks of the data set that have been modified since creation of a prior snapshot of the data set;
• upload the snapshot to a cloud object storage platform of a cloud infrastructure, wherein the snapshot is uploaded as a plurality of log segments conforming to an object format of the cloud object storage platform, and wherein each log segment includes:
• one or more data blocks in the plurality of data blocks;
• and
• a first set of metadata comprising, for each of the one or more data blocks, an identifier of the data set, an identifier of the snapshot, and a logical block address (LBA) of the data block;
• and
• communicate the first set of metadata to a server component running in a cloud compute and block storage platform of the cloud infrastructure.
