Archiving data in cloud/object storage using local metadata staging

A non-transitory computer readable storage medium having stored thereon program code executable by a computer system residing at an on-premises site comprising on-premises storage, the program code embodying a method for archiving data in cloud/object storage using local metadata staging, the method comprising:

• receiving a snapshot of a dataset to be archived, the snapshot including data of the dataset;
• packaging the data included in the snapshot into one or more fixed-size data chunks and uploading the one or more fixed-size data chunks to the cloud/object storage;
• concurrently with the packaging and the uploading, staging metadata for the snapshot in the on-premises storage;
• and
• upon uploading all of the data of the snapshot one or more fixed-size data chunks, uploading the metadata staged in the on-premises storage to the cloud/object storage.

A computer system residing at an on-premises site including on-premises storage, the computer system comprising:

• a processor;
• and
• a non-transitory computer readable medium having stored thereon program code that, when executed, causes the processor to:
• receive a snapshot of a dataset to be archived, the snapshot including data of the dataset;
• package the data included in the snapshot into one or more fixed-size data chunks and uploading the one or more fixed-size data chunks to cloud/object storage;
• concurrently with the packaging and the uploading, stage metadata for the snapshot in the on-premises storage;
• and
• upon uploading all of the one or more fixed-size data chunks, upload the metadata staged in the on-premises storage to the cloud/object storage.
