The system, code, and method store debugging logs throughout an operation. At predetermined points the logs are stored to a cache. Older and/or unnecessary logs are periodically deleted from the cache to ensure that the cache does not grow to be larger than a predetermined size. This avoids the need to re-run a scenario after an error occurs in order to produce troubleshooting/debugging information. ## Claims ### Claim 1 A method for dynamically producing a debug log, comprising: detect initiation of an operation, wherein the operation is a backup operation; produce a debug log for a predetermined portion of the operation, wherein operation is divided into a plurality of portions, wherein the each of the plurality of portions is identified using one of a plurality of checkpoints in code for the operation, and wherein the predetermined portion is one of the plurality of portions; store the debug log for the predetermined portion in a dynamic logger cache, wherein: if the operation fails during the predetermined portion, write the debug log stored in the dynamic logger cache to a debug log file in persistent storage; or if the operation does not fail during the predetermined portion, delete the debug log in the dynamic logger cache according to a predefined procedure, wherein the predetermined portion is identified using a first checkpoint of the plurality of checkpoints, wherein the predefined procedure specifies deleting the debug log when a second checkpoint of the plurality of checkpoints is reached, and wherein the second checkpoint is reached after the first checkpoint; and repeat the producing and storing of the debug log for each portion of the operation until either the operation ends or a portion of the operation fails. ### Claim 2 (depends on 1) The method of claim 1, wherein the debug log is produced by a data protection manager. ### Claim 3 (depends on 1) The method of claim 1, wherein the debug log is enabled by default. ### Claim 4 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, the method comprising: detecting initiation of an operation, wherein the operation is a backup operation; producing a debug log for a predetermined portion of the operation, wherein operation is divided into a plurality of portions, wherein the each of the plurality of portions is identified using one of a plurality of checkpoints in code for the operation, and wherein the predetermined portion is one of the plurality of portions; storing the debug log for the predetermined portion in a dynamic logger cache, wherein: if the operation fails during the predetermined portion, write the debug log stored in the dynamic logger cache to a debug log file in persistent storage; or if the operation does not fail during the predetermined portion, delete the debug log in the dynamic logger cache according to a predefined procedure, wherein the predetermined portion is identified using a first checkpoint of the plurality of checkpoints, wherein the predefined procedure specifies deleting the debug log when a second checkpoint of the plurality of checkpoints is reached, and wherein the second checkpoint is reached after the first checkpoint; and repeating the producing and storing of the debug log for each portion of the operation until either the operation ends or a portion of the operation fails. ### Claim 5 (depends on 4) The non-transitory computer readable medium of claim 4, wherein the debug log is produced by a data protection manager. ### Claim 6 An electronic device comprising: a dynamic logger cache; a persistent storage; a processor; and a memory having computer program instructions stored thereon, the processor executing the computer program instructions in the memory to perform a method comprising of: detecting initiation of an operation, wherein the operation is a backup operation, wherein operation is divided into a plurality of portions, wherein the each of the plurality of portions is identified using one of a plurality of checkpoints in code for the operation, wherein the predetermined portion is one of the plurality of portions; producing a debug log for a predetermined portion of the operation; storing the debug log for the predetermined portion in the dynamic logger cache, wherein: if the operation fails during the predetermined portion, writing the debug log stored in the dynamic logger cache to a debug log file in the persistent storage; or if the operation does not fail during the predetermined portion, delete the debug log in the dynamic logger cache according to a predefined procedure, wherein the predetermined portion is identified using a first checkpoint of the plurality of checkpoints, wherein the predefined procedure specifies deleting the debug log when a second checkpoint of the plurality of checkpoints is reached, and wherein the second checkpoint is reached after the first checkpoint; and repeating the producing and storing of the debug log for each portion of the operation until either the operation ends or the operation fails.
