10. The computer-implemented method of claim 1 further comprising:

responsive to a user-supplied request to restore at least part of the primary dataset from backup storage in the cloud storage environment, initiating a restore operation comprising:

restoring backed-up payload data of the at least part of the primary dataset from the second cloud storage tier to the first cloud storage tier, and

restoring the backed-up payload data of the at least part of the primary dataset from the first cloud storage tier to data storage device associated with the user-supplied request to restore.

11. A computer-implemented method for backing up and restoring backed-up data using different cloud storage tiers, the computer-implemented method comprising:

by one or more computing devices comprising one or more hardware processors and computer memory:

defining a storage policy for backing up a primary dataset based on user-supplied selections,

wherein the storage policy comprises a data structure or file for storing one or more preferences or criteria for performing operations on primary or secondary copies of data associated with the storage policy,

wherein a first user-supplied selection indicates a first cloud storage tier of a cloud storage environment comprising a plurality of cloud storage tiers,

wherein a second user-supplied selection indicates a second cloud storage tier of the cloud storage environment,

wherein the storage policy indicates that, in a backup operation of the primary dataset, payload data of the primary dataset is to be backed up into the second cloud storage tier in the cloud storage environment, and

further indicates that metadata collected in the backup operation of the primary dataset and a backup index associated with the backup operation are to be stored into the first cloud storage tier in the cloud storage environment;

wherein the first cloud storage tier is distinct from the second cloud storage tier in at least one of: allowing data to be accessed more frequently than the second cloud storage tier, providing faster data retrieval than the second cloud storage tier, costing more per unit of data storage than the second cloud storage tier, costing more for reading from and writing data to the first cloud storage tier than the second cloud storage tier, and lacking minimum stay charges for data at the first cloud storage tier;

storing the storage policy in a database;

initiating a first backup operation of the primary dataset according to the storage policy,

wherein based on the storage policy, backed-up payload data of the primary dataset is transmitted to the second cloud storage tier, backed-up metadata collected in the first backup operation is transmitted to the first cloud storage tier, and the backup index associated with the backup operation is transmitted to the first cloud storage tier; and

presenting in a user interface, browsing information about the backed-up payload data,

the backup index, and

the metadata in the first cloud storage tier without accessing the backed-up payload data in the second cloud storage tier.

12. The computer-implemented method of claim 11 further comprising:

presenting to a user through a user interface:
