A system enables selection of application hosts which meet update requirements, then downloads an update for instances of an application agent corresponding to selected application hosts. The system puts selected application hosts in maintenance mode, which prevents selected application hosts from beginning execution of any operations, until updating selected application hosts is completed. The system creates backup copy of configuration files used to configure instances of application agent. The system initiates update sessions which install update in instances of application agent corresponding to selected application hosts. If update sessions failed to install update in any of instances of application agent in cluster of application hosts, then system restores configuration files which were used to configure instances of application agents. The system rolls back update for updated instances of application agents in cluster of application hosts to previous conditions and configurations of instances of application agents.

Restoring configuration files to rollback agent updates when cluster updates fail

Updating application hosts in a cluster are described. A system enables a selection of an application host which meet update requirements, and then determines whether the selected application host is in a cluster of application hosts. If the selected application host is in a cluster, then the system determines whether each application host in the cluster is selected for updating. If each application host in the cluster is not selected for updating, then the system enables the selection of all application hosts in the cluster for updating. If each application host in the cluster is selected for updating, then the system initiates update sessions which install updates in components of the cluster. If at least some of the application hosts in the cluster are not updated, then the system rolls back all updated application hosts in the cluster to previous conditions of the updated application hosts.

Updating application hosts in a cluster

System selects application hosts which meet update requirements, then downloads update for instances of application agent corresponding to selected application hosts. System puts selected application hosts in maintenance mode, which prevents selected application hosts from beginning execution of any operations, until updating selected application hosts is completed. System creates backup copy of state of instances of application agent. System generates installation instructions that, when executed by update sessions to install update, enable roll back from updated instances of application agent to state of instances of application agent recorded in backup copy. System initiates update sessions which install update in instances of application agent corresponding to selected application hosts. If update sessions failed to install update in any instances of application agent in cluster of application hosts, system rolls back update for updated instances of application agents in cluster to previous conditions and configurations of instances of application agents.

Generating installation software that rolls back agent updates when cluster updates fail

System enables selection of application hosts which meet update requirements, then downloads update for instances of application agent corresponding to selected application hosts. System puts selected application hosts in maintenance mode, which prevents selected application hosts from beginning execution of any operations, until updating selected application hosts is completed. System creates copy of instructions, which when executed, installs update in instance of application agent in one of application hosts, and reports on update process to server which communicates with application hosts. System launches worker process from copy of instructions. System initiates update sessions which install update in instances of application agent corresponding to selected application hosts. If update sessions failed to install update in any of instances of application agent in cluster of application hosts, system rolls back update for updated instances of application agents in cluster of application hosts to previous conditions of instances of application agents.

Launching copies of installation software that rolls back agent updates when cluster updates fail

One example method includes receiving a first message specifying that one or more changes have been made to infrastructure assets of a storage array. In response to receiving the first message, a change table stored in a database is updated to specify the one or more changes made to the infrastructure assets, the change table including a unique index offset value for each of the one or more changes. Based on the unique index offset value, it is determined if the one or more changes are to be communicated to a backup engine or client. When it is determined that the one or more change are to be communicated to the backup engine or client, a second message is sent to the backup engine or client that notifies the backup engine or client of the one or more changes made to the infrastructure assets of the storage array.

Generic 'differential discovery service' for use in any storage array to provide differential discovery of the infrastructure assets to any client

Agent lifecycle management for backup and restore applications is described. A system enables selection of application hosts, each of which meets installation requirements for installing instances of application agents from a backup and restore application, then downloads, in parallel, the instances of the application agent to the corresponding selected application hosts. The system installs, in parallel, the instances of the application agent in the corresponding selected application hosts, then registers, in parallel, the instances of the application agent with the backup and restore application. The system subsequently initiates sessions which download and install, in parallel, an update in instances of the application agent in in corresponding application hosts. The system unregisters at least one of the instances of the application agent, in at least one application host, from the backup and restore application. The system decommissions the at least one application host from protection by the backup and restore application.

Agent lifecycle management for backup and restore applications

Automatically updating agents from backup and restore applications is described. A system enables selection of application hosts which meet update requirements, then downloads an update for instances of an application agent corresponding to selected application hosts. The system puts selected application hosts in maintenance mode, which prevents selected application hosts from beginning execution of any operations, until updating selected application hosts is completed. The system initiates update sessions which install update in instances of application agent corresponding to selected application hosts. If update sessions did not fail to install update in any of instances of application agent in cluster of application hosts, then the system stores the updated instances of the application agents in a non-volatile storage.

Automatically updating agents from backup and restore applications

The present invention provides a system, computer readable code and method for dynamically performing debugging. 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.
