System and method to build dependency chain for snapshot-based backups

A non-transitory computer readable medium comprising computer readable program code, which when executed by a computer processor enables the computer processor to perform a method for performing backup operations, the method comprising:

• determining, by a secondary backup storage system, that a first backup operation has completed and produced a first protection copy of a plurality of assets stored in a client storage array, wherein a primary backup storage system is used to obtain a snapshot-based backup from the client storage array and provide the snapshot-based backup to the secondary backup storage system, wherein the first protection copy is generated using the snapshot-based backup;
• identifying a second backup operation that was started before the first backup operation was started;
• determining that the second backup operation successfully produced a second protection copy;
• and
• generating linking metadata that links the first protection copy to the second protection copy in response to determining that the second backup operation successfully produced the second protection copy, wherein linking metadata is used to restore at least a portion of the assets during a restore operation.

• identifying a second backup operation that was started before the first backup operation was started, wherein the second backup operation is a full backup operation;
• determining that the second backup operation is ongoing;
• waiting, in response to determining that the second backup operation is ongoing, until the second backup operation is complete;
• determining that the second backup operation successfully produced a second protection copy;
• and
• generating linking metadata that links the first protection copy to the second protection copy in response to determining that the second backup operation successfully produced the second protection copy, wherein linking metadata is used to restore at least a portion of the assets during a restore operation.
