Abstract: A method includes identifying relationships between containers on a first device, where each container includes at least one relationship that includes a HAS-A relationship or an IS-A relationship. The method also includes creating, on a second device, a first set of twin containers, where each container in the first set of twin containers corresponds to a container that includes only the HAS-A relationships. In addition, the method includes creating, on the second device and in response to creating the first set of twin containers, a second set of twin containers where each container in the second set of twin containers corresponds to a container that includes at least one IS-A relationship. Moreover, the method includes determining and performing a twin container start-up sequence for the first set and the second set of twin containers.

Abstract: Embodiments of the invention relate to methods and systems for efficiently backing up a production host. In one or more embodiments, assets are assigned to one or more slices. Depending on the type of assets assigned to a slice such as directory information versus data, the slices are assigned a flag. This flag may then be used to determine which streams a slice should be assigned to and based on the specific flags of the slices assigned to each stream, the order by which the streams are transferred to backup containers located in a backup storage may be determined. This may result in better or more efficient utilization of available connections between the containers and the production host, resulting in better utilization of system and network resources as well as a better backup and recovery performance.

Abstract: A method for managing a data protection module (DPM) includes: obtaining an alert generated by the DPM within a predetermined period of time; obtaining metadata associated with the DPM; analyzing the metadata to extract relevant data; analyzing the alert to extract second relevant data; making, based on the second relevant data, a determination that a tolerance level associated with the alert has been exceeded; sending, based on the determination, the alert, the relevant data, and the second relevant data to a vendor environment (VE) analyzer; in response to sending the alert, the relevant data, and the second relevant data, receiving a service request (SR) generated by the VE analyzer for the DPM; and providing the SR to the client to notify a user of the client about the SR using a graphical user interface (GUI) of the client.

Abstract: In general, one or more embodiments of the invention relates to systems and methods for performing a backup and later determining a level or percentage of corruption of the resulting backup set. By having a cyber-security module analyze the backup data periodically, corruption of backup data both caused by cyber-attacks or by hardware failures may be detected and characterized. By knowing how corrupted a particular corrupted backup data set is, an informed decision may be made with regards to purging the backup data set and/or using the backup data set or portion thereof in any further restorations. By making these determinations, a quick identification of possible ransomware attacks may be made, and additional degradation of a user's data may be avoided.

Abstract: A method for efficiently sharing assets such as files and folders in the form of slices. Assets are shared or transferred between a host computer system and a target computer system such as a client computer system. In one or more embodiments, assets such as files and folders that are to be shared or transferred are placed in appropriate network slice queues by the hosts in such a manner that each slice has a size that is the same as the others within a predetermined tolerance. This ensures efficient use of network resources when sharing or transferring the files, while minimizing the amount of work the hosts and/or clients must perform.

Abstract: A registry writer is instructed via a copy service on a host to prepare for generation of a snapshot. The registry writer is responsible for saving system hive files to disk before the snapshot is generated. A reporting of the system hive files is received from the registry writer. Communications are exchanged with an API exposed by an operating system of the host to identify user hive files. The system hive files reported by the registry writer and the user hive files identified using the API exposed by the operating system are backed up from the snapshot to secondary storage.

Abstract: 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.

Abstract: Selecting, authenticating, and installing individual components of agent software stacks is described. A system enables a selection of a component of an application agent software stack from a backup and restore application, from displayed components of multiple application agent software stacks. The system downloads the selected component of the application agent software stack from the backup and restore application. The system downloads a digital certificate from a vendor of the backup and restore application or the backup and restore application. The system uses a public key from the downloaded digital certificate to authenticate the selected component of the application agent software stack. The system installs an instance of the authenticated component of the application agent software stack in an application host, which executes the instance of the authenticated component to create a backup copy of data generated by an application executed by the application host.

Abstract: 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.

Abstract: 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.
