One or more of the operations at the cloud storage site may be performed by an Object Lambda function that has been configured by a dedupe application. ## Claims ### Claim 1 A method, comprising: receiving, at a cloud storage site from a dedupe application, a write request that identifies an object to be written to the cloud storage site; storing the object at the cloud storage site; receiving, at the cloud storage site from the dedupe application, a read request that identifies the object; in response to receiving the read request, performing, at the cloud storage site, an evaluation of the object to determine if the object is corrupted; and sending, from the cloud storage site to the dedupe application, a message identifying an outcome of the evaluation. ### Claim 2 (depends on 1) The method as recited in claim 1, wherein the performing of the evaluation is carried out by an Object Lambda function hosted at the cloud storage site. ### Claim 3 (depends on 2) The method as recited in claim 2, wherein operation of the lambda function is automatically triggered by receipt, at the cloud storage site, of the read request. ### Claim 4 (depends on 1) The method as recited in claim 1, wherein the message indicates either that the object is corrupted, or that the object is not corrupted. ### Claim 5 (depends on 1) The method as recited in claim 1, wherein when the evaluation indicates that the object is not corrupted, a write operation for the object is marked as complete. ### Claim 6 (depends on 1) The method as recited in claim 1, wherein an Object Lambda function that carries out the evaluation is configured by the dedupe application so that the Object Lambda function includes logic to iterate, parse, and validate the data in the object. ### Claim 7 (depends on 1) The method as recited in claim 1, wherein a configuration of the lambda function is determined based on a requirement of the dedupe application. ### Claim 8 (depends on 1) The method as recited in claim 1, wherein the object is deduplicated prior to being stored at the cloud storage site. ### Claim 9 (depends on 1) The method as recited in claim 1, wherein no data is downloaded from the cloud storage site by the dedupe application. ### Claim 10 A non-transitory storage medium having stored therein instructions that are executable by one or more hardware processors to perform operations comprising: receiving, at a cloud storage site from a dedupe application, a write request that identifies an object to be written to the cloud storage site; storing the object at the cloud storage site; receiving, at the cloud storage site from the dedupe application, a read request that identifies the object; in response to receiving the read request, performing, at the cloud storage site, an evaluation of the object to determine if the object is corrupted; and sending, from the cloud storage site to the dedupe application, a message identifying an outcome of the evaluation. ### Claim 11 (depends on 10) The non-transitory storage medium as recited in claim 10, wherein the performing of the evaluation is carried out by an Object Lambda function hosted at the cloud storage site. ### Claim 12 (depends on 11) The non-transitory storage medium as recited in claim 11, wherein operation of the lambda function is automatically triggered by receipt, at the cloud storage site, of the read request. ### Claim 13 (depends on 10) The non-transitory storage medium as recited in claim 10, wherein the message indicates either that the object is corrupted, or that the object is not corrupted. ### Claim 14 (depends on 10) The non-transitory storage medium as recited in claim 10, wherein when the evaluation indicates that the object is not corrupted, a write operation for the object is marked as complete. ### Claim 15 (depends on 10) The non-transitory storage medium as recited in claim 10, wherein an Object Lambda function that carries out the evaluation is configured by the dedupe application so that the Object Lambda function includes logic to iterate, parse, and validate the data in the object. ### Claim 16 (depends on 10) The non-transitory storage medium as recited in claim 10, wherein a configuration of the lambda function is determined based on a requirement of the dedupe application. ### Claim 17 (depends on 10) The non-transitory storage medium as recited in claim 10, wherein the object is deduplicated prior to being stored at the cloud storage site. ### Claim 18 (depends on 10) The non-transitory storage medium as recited in claim 10, wherein no data is downloaded from the cloud storage site by the dedupe application.
