listening, on a communication port that is connected to the entity, for a request from the entity for the available bandwidth information; receiving, from the entity, the request for the available bandwidth information; and sending, to the entity, the available bandwidth information in response to the request for the available bandwidth information. ### Claim 2 (depends on 1) The method as recited in claim 1, wherein the method is performed by a diagnostic tool residing on a backup server. ### Claim 3 (depends on 1) The method as recited in claim 1, wherein measurement of the available bandwidth is performed in response to the triggering of a backup. ### Claim 4 (depends on 1) The method as recited in claim 1, wherein measurement of the available bandwidth is performed in response to the storage of a backup. ### Claim 5 (depends on 1) The method as recited in claim 1, wherein the entity comprises a client, and the available bandwidth information is usable by the client to determine a bandwidth requirement for a backup operation. ### Claim 6 (depends on 1) The method as recited in claim 1, wherein the entity comprises either a storage server or a client. ### Claim 7 (depends on 1) The method as recited in claim 1, further comprising using the available bandwidth information as a basis for correcting a problem in a computing system that includes the entity and the server. ### Claim 8 (depends on 1) The method as recited in claim 1, further comprising: receiving, from the entity, a request for data deduplication rate (DDR) information; querying a database for the DDR information; obtaining the DDR information; and returning the requested DDR information to the entity. ### Claim 9 (depends on 8) The method as recited in claim 8, wherein the DDR information is associated with a particular plugin. ### Claim 10 (depends on 8) The method as recited in claim 8, wherein the DDR information comprises historical DDR information concerning a completed backup operation and/or a completed restore operation. ### Claim 11 A non-transitory storage medium having stored therein computer-executable instructions which, when executed by one or more hardware processors, implement and/or cause the implementation of the following operations: measuring an available bandwidth of a communication path between a server and an entity, wherein the measuring generates available bandwidth information; listening, on a communication port that is connected to the entity, for a request from the entity for the available bandwidth information; receiving, from the entity, the request for the available bandwidth information; and sending, to the entity, the available bandwidth information in response to the request for the available bandwidth information. ### Claim 12 (depends on 10) The non-transitory storage medium as recited in claim 10, wherein the operations are performed by a diagnostic tool residing on a backup server. ### Claim 13 (depends on 10) The non-transitory storage medium as recited in claim 10, wherein measurement of the available bandwidth is performed in response to the triggering of a backup. ### Claim 14 (depends on 10) The non-transitory storage medium as recited in claim 10, wherein measurement of the available bandwidth is performed in response to the storage of a backup. ### Claim 15 (depends on 10) The non-transitory storage medium as recited in claim 10, wherein the entity comprises a client, and the available bandwidth information is usable by the client to determine a bandwidth requirement for a backup operation. ### Claim 16 (depends on 10) The non-transitory storage medium as recited in claim 10, wherein the entity comprises either a storage server or a client. ### Claim 17 (depends on 10) The non-transitory storage medium as recited in claim 10, wherein the operations further comprise: receiving, from the entity, a request for data deduplication rate (DDR) information; querying a database for the DDR information; obtaining the DDR information; and returning the requested DDR information to the entity. ### Claim 18 (depends on 17) The non-transitory storage medium as recited in claim 17, wherein the DDR information is associated with a particular plugin. ### Claim 19 (depends on 17) The non-transitory storage medium as recited in claim 17, wherein the DDR information comprises historical DDR information concerning a completed backup operation and/or a completed restore operation. ### Claim 20 (depends on 11) A server, comprising: one or more hardware processors; and the non-transitory storage medium as recited in claim 11.
