Abstract

Described herein are techniques for better understanding problems arising in an illustrative information management system, such as a data storage management system, and for issuing appropriate alerts and reporting to data management professionals. The illustrative embodiments include a number of features that detect and raise awareness of anomalies in system operations, such as in deduplication pruning operations. Such anomalies can include delays in the processing of archive files to be deleted and/or delays in the generation of the list of archive files to delete. Anomalies are characterized by frequency anomalies and/or by occurrence counts. Utilization is also of interest for certain key system resources, such as deduplication databases, CPU and memory at the storage manager, etc., without limitation. Predicting low utilization periods for these and other key resources is useful for scheduling maintenance activities without interfering with ordinary deduplication pruning operations and/or other data protection jobs.

Claims20

Dependent claims

A networked information management system comprising:

a client computing device having one or more first hardware processors, wherein the client computing device is associated with a first job;
and
one or more computing devices in communication with the client computing device, wherein the one or more computing devices are configured with computer-executable instructions that, when executed, cause the one or more computing devices to:
retrieve jobs data corresponding to the first job and the first client computing device;
perform a time-series decomposition of the jobs data;
analyze a component of the decomposed time-series to determine at least one of an acceptable range for time to perform the first job, an acceptable range for a size of secondary copy data associated with the first job, or an acceptable range for a number of job attempts until the first job is complete;
determine a possible cause for the first job running longer than the acceptable range for time to perform the first job in response to the first job at a first time running longer than the acceptable range for time to perform the first job;
determine whether any events corresponding to the first job are anomalous;
and
generate an alert regarding an issue with the networked information management system in response to at least one of the first job running longer or a first event corresponding to the first job being anomalous.

7 more elements

A computer-implemented method comprising:

retrieving jobs data corresponding to a first job and a first client computing device;
performing a time-series decomposition of the jobs data;
analyzing a component of the decomposed time-series to determine at least one of an acceptable range for time to perform the first job, an acceptable range for a size of secondary copy data associated with the first job, or an acceptable range for a number of job attempts until the first job is complete;
determining a possible cause for the first job running longer than the acceptable range for time to perform the first job in response to the first job at a first time running longer than the acceptable range for time to perform the first job;
determining whether any events corresponding to the first job are anomalous;
and
generating an alert regarding an issue with a networked information management system in response to at least one of the first job running longer or a first event corresponding to the first job being anomalous.

4 more elements

A non-transitory computer-readable medium storing instructions, which when executed by one or more computing devices, cause the one or more computing devices to perform a method comprising:

retrieving jobs data corresponding to a first job and a first client computing device;
performing a time-series decomposition of the jobs data;
analyzing a component of the decomposed time-series to determine at least one of an acceptable range for time to perform the first job, an acceptable range for a size of secondary copy data associated with the first job, or an acceptable range for a number of job attempts until the first job is complete;
determining a possible cause for the first job running longer than the acceptable range for time to perform the first job in response to the first job at a first time running longer than the acceptable range for time to perform the first job;
determining whether any events corresponding to the first job are anomalous;
and
generating an alert regarding an issue with a networked information management system in response to at least one of the first job running longer or a first event corresponding to the first job being anomalous.
