Backup schedule optimization is provided. Data describing a first backup schedule for a first backup server is identified. Performance metric data and workload data for a first backup server and a second backup server is collected. If a count of backup windows represented by workload data for the first backup server exceeds a data collection threshold, an updated backup schedule that offloads a pending job from the first backup server to the second backup server can be generated. The updated backup schedule is generated if a maximum average I/O threshold for the first backup server was exceeded while a minimum average I/O threshold for the second backup server was deceeded. The maximum and minimum average I/O thresholds are calculated based on respective target average I/O rates for the first and second backup servers, the target average I/O rates derived from respective perform metric data.

Optimizing data backup schedules

Embodiments of the present invention provide methods, program products, and systems for determining an amount of usable storage in a backup environment. Embodiments of the present invention can be used to receive system information pertaining to a storage backup environment. Embodiments of the present invention can calculate a compression ratio of the storage on a backup server and a backup ratio between an amount of data on a client computer system and an amount of data on the backup server and calculate an average amount of storage consumed on the backup server. Embodiments of the present invention can determine an existing backup capacity for the storage backup environment by identifying an amount representing the actual capacity of data capable of being stored on the backup server and reducing the amount representing the actual capacity according to the calculated average amount of storage consumed on the backup server.

Capacity management

Backup schedule optimization is provided. Backup environment data is identified. Data describing a first backup schedule is identified. Performance metric data that includes data for a data storage array of computer data storage device(s) of a backup server is collected. Data describing backup log(s) that associated with jobs backed up to the data storage array and respectively executed during backup window(s) is received. A target average I/O rate is determined based on the performance metric data of the data storage array. A second backup schedule is generated based on the target average I/O rate, average I/O rate(s) of the data storage array, the backup environment data, and the data describing one or more backup logs. A start time of a job is scheduled in the second backup schedule for a different time in a backup window compared to a start time of the job in the first backup schedule.

A method, computer system and computer program product for managing tapes storing a backup for a node. The method identifies the node for which a current set of tapes is present. The method determines whether the current set of tapes exceeds a threshold for undesired fragmentation for the node and moves data in the current set of tapes to a new set of tapes when a physical tape count exceeds the threshold for undesired fragmentation, wherein the data is more contiguous in the new set of tapes than the current set of tapes.

Backup consolidation

In a distributed computing environment, a method, system and program product for monitoring, from a client computer system the performance of an application program residing on a server computer system. A probe program residing at the client computer generates requests for the services of the application program and records transaction records based upon service responses therefrom. The requests and transaction record generation is controlled by a set of probe configuration information at the client computer. Transaction records are provided to a central repository whereat statistical information is pre-processed and inserted into statistics tables. A display system enables a computer user to interactively request and view a plurality of displays of data sets of the monitoring data. Each data set includes data elements which may be interactively indicated by the viewer to cause the retrieval and display of related data sets having data elements associated with those in the original display.
