One example method includes receiving, by a first computing entity from a second computing entity, a request for data, providing, by the first computing entity, a compliance API (Application Program Interface) to the second computing entity, receiving, by the first computing entity from the second computing entity, location information and/or data compliance information, by way of the compliance API, consulting, by the first computing entity, a mapping, and determining, based on information in the mapping and the location information and/or data compliance information, whether or not the data is permitted to be transmitted by the first computing entity to the second computing entity, and either transmitting the data to the second computing entity, or not transmitting the data to the second computing entity, based on data tags, the information in the mapping and the location information and/or data compliance information.

Restricted data transfer

According to various embodiments, a method, medium, and system for exporting log messages related to a particular job running in a micro services system is described in this disclosure. The method uses a mapping table to narrow down the search scope for finding relevant log files. The mapping table maps a job attribute combination to one or more micro services, and thus will direct the search for relevant log messages only to those log files related to the one or more micro services. The search scope can be further narrowed down using a start time and end time of the job. Once the relevant log files are found, log messages containing an identifier of the job can be extracted from the relevant log files for display or for a user to download. The mapping table can be automatically generated by parsing through historical files in a system non-busy time.

A current retention mode is identified as being one of conservative or aggressive. When the retention mode is identified as aggressive, a check is made as to whether used space on backup storage is below a lower threshold. If the used space is below the lower threshold, a switch is made into the conservative mode. If the used space is above the lower threshold, the aggressive mode is maintained. While in the aggressive mode, a backup chain of a database is selected for pruning, the selected backup chain having a shortest retention term of all backup chains not yet pruned and not being a latest backup chain. Log backups of the database in the selected backup chain are identified. Each log backup that has expired is deleted regardless of dependency of other backups on an expired log backup.

Self-adaptive copy retention management

A method, apparatus, and system for performing a Location SLO check based on a location scatter table is disclosed. A location scatter table is maintained, the location scatter table indicative of updated geographical location distribution of all backups of all assets. A Location Service Level Objective (SLO) associated with a first asset is determined, the Location SLO associated with the first asset specifying one or more allowed locations where backups of the first asset are permitted to be located. All locations where at least one backup of the first asset is located are determined. A Location SLO check for the first asset is performed, wherein the Location SLO check passes when all the locations where at least one backup of the first asset is located fall within the allowed locations specified by the Location SLO.

Efficient way to perform location SLO validation

A method and system for efficient virtual machine operation while recovering data. Specifically, the disclosed method and system enable the activation of virtual machines while virtual machine data, pertinent to the virtual machines, may concurrently be undergoing restoration. By activation, virtual machines may be permitted to issue input-output operations targeting their respective virtual machine data. Further, whether or not the sought virtual machine data has been recovered, fulfillment of the input-output operations may entail accessing virtual machine data either stored locally or retained remotely on a backup storage service.

Responsibility for protecting a distributed file system is split across different client hosts. Each client host is assigned a subset of the distributed file system to backup. An index host is identified to create a common namespace under which different client file indexes generated by the different client hosts during backups of respective subsets of the file system will be maintained. During backups, different client file indexes are received from the different client hosts. The client file indexes include metadata about files in the file system included in the backups. Each of the different client file indexes are associated to the same common namespace to provide a unified view of all files across all subsets of the file system that have been backed up by the different client hosts.

Protecting large distributed file systems

Described is a system for utilizing fully dynamic proxies for data flow during data protection. The system determines threshold parameters for each respective virtual proxy in a plurality of virtual proxies. The system receives virtual machine protection data of each respective virtual proxy. The system detects a current data protection workload experienced by each virtual proxy operating according to its respective threshold parameters and virtual machine protection data. The system identifies at least one under-utilized virtual proxy and at least one over-utilized virtual proxy based on the current data protection workload detected on each virtual proxy. The system causes the at least one under-utilized virtual proxy to receive upcoming backup data flow before the at least one over-utilized virtual proxy.

Fully dynamic virtual proxies for data protection

A efficient method for long-term retention backup policy within recovery point objectives (RPO). Specifically, the disclosed method proposes a dynamic promotion scheme through which short-term retention backup copies, in compliance with specified long-term retention RPOs, may be promoted to render long-term retention backup copies. Further, the disclosed method not only looks to past and/or presently dated short-term retention backup copies, but also looks to prospective (or future) dated short-term retention backup copies, which are expected or predicted to be produced, for promotion. Moreover, in circumstances where there are no appropriate past, present, or future dated short-term retention backup copies to promote, the disclosed method triggers new backup operations to acquire the long-term retention backup copies necessary to maintain the specified long-retention RPOs.

Efficient method for optimizing long-term retention backup policy within recovery point objectives (RPO)

One example method includes moving a volume from a source server to a target server. In one example, the volume is moved and the need to copy the source data is eliminated. The volume to be moved is selected and metadata associated with the save sets stored on the volume is exported to a volume bootstrap, which is also stored on the selected volume. The volume is mounted or attached to the target server and the metadata is imported from the volume bootstrap. The volume is made read/write and is moved from the source server to the target server.

Protected saveset volume movement via metadata bootstrap

An application is provided as a compound virtual appliance having components to be hosted by virtual machines. Each component includes a set of virtual machine disks. Partial versions of the components are created by removing from each component each virtual machine disk determined to be a duplicate of a virtual machine disk of another component. A compact version of the compound virtual appliance is created by packing together the partial versions of the components and a single copy of each virtual machine disk having been determined to be a duplicate. The compact compound virtual appliance is deployed to a customer site. At the customer site, a complete version of the compound virtual appliance is reconstructed by adding back the single copy of each virtual machine disk having been determined to be a duplicate into each component having had the duplicate virtual machine disk removed.

Systems and methods to decrease the size of a compound virtual appliance file

Embodiments are described for performing online migration of backup appliances in automated and monitored process from a backup application. The data migration process uses certain Mtree replication methods. It is configured to provide capabilities a backup application server would control, such as Mtree replication configuration from the backup application, a policy driven approach for data center migration, and accommodation of specific customer data recovery needs, and providing a choice to end users for leveraging both Managed File Replication and Mtree replication based on the customer data movement requirements. Such a solution is configured to be generic and applicable to any data protection applications with a policy driven implementation that leverages certain integration points of the system.

Systems and methods for performing a data transfer in a data protection system are disclosed. A user interface is provided that includes a workflow. The workflow is effective to configure a data transfer by identifying the source of the data, the destination of the data, and the data itself. A data control process associated with the data protection system is performed to authenticate the requesting user and determine whether the user is authorized to access the data. The data is transferred in accordance with the data control process of the data protection system.

Data transfer in a data protection system

A remote agent for providing backup services to applications includes a persistent storage and a backup manager. The persistent storage stores backup policies for the applications. The backup manager identifies an application of the applications for providing the backup services; generates an application backup template based on a backup policy of the backup policies for the application; sends the generated application backup template to a production host that hosts the application; and makes a determination that the backup policy has been triggered. In response to the determination, the backup manager initiates a native data extraction from the application using the application backup template to obtain a native data dump; stores the native data dump in backup storage; and indexes the stored native data dump as a backup.

System and method for orchestrated application protection

First and second types of weighted values are assigned to graph edges of a directed acyclic graph representing versions of a software product. The first type of weighted values indicate a degree of stability associated with upgrading the product. The second type of weighted values indicate an estimated time for the upgrading. A first upgrade path through the graph is generated using the first type of weighted values and corresponds to a first upgrade plan that minimizes risks associated with the upgrade. A second upgrade path through the graph is generated using the second type of weighted values and corresponds to a second upgrade plan that minimizes the estimated upgrade time. An upgrade package is created for one of the first or second upgrade plans. The upgrade package includes the desired version, intermediate versions, and a sequence indicating an order in which the intermediate versions should be installed.

Providing different upgrade paths for upgrading a server

Software product versions installed on clients are detected. At least a subset of clients have different versions. Directed acyclic graphs are built specific to a client based on a particular version of the software product installed. Weighted values are assigned to edges in each graph. The weighted values indicate a degree of stability associated with upgrading the software product or an estimated time associated with the upgrading. Upgrade paths present in each graph are traversed to calculate sums of the weighted values. Based on the sums, recommended upgrade paths for the clients are identified, each recommended upgrade path is specific to a respective client. Upgrade packages, corresponding to the recommended upgrade paths, are created for the clients. Each upgrade package is specific to the respective client, includes the desired version of the software product, intermediate versions, and a sequence indicating an order in which the intermediate versions should be installed.
