One example method includes generating in a shared protection namespace a first point-in-time copy of a first working frozen copy of an active namespace that includes first files associated with the active namespace that are stacked in a first horizontal file. A retention lock is applied to the first horizontal file. A second point-in-time copy of a second working frozen copy of the active namespace that includes second files associated with the active namespace that are stacked in a second horizontal is generated. A retention lock is applied to the second horizontal file. The second horizontal file is generated by copying files from the first horizontal file into the second horizontal file and copying files from the second working frozen copy of the active namespace into the second horizontal file.

Efficient retention locking of a copy of a large namespace on a deduplication filesystem

One example method includes generating first and second snapshots of a shared protection namespace of a backup storage device. The first snapshot includes a first working frozen copy of an active namespace and the second snapshot includes a second work working frozen copy of the active namespace. First and second point-in-time copies of the first and second working frozen copies are generated in the shared protection namespace. The first point-in-time copy includes first files extracted from the first working frozen copy and that are stacked in at least one first horizontal file. The second point-in-time copy includes the second files included in the second working frozen copy that are stacked in at least one second horizontal file. A retention lock is applied to the at least one first and second horizontal files.

One example method includes generating first and second snapshots of a shared protection namespace of a backup storage device. The first snapshot includes a first working frozen copy of an active namespace and the second snapshot includes a second work working frozen copy of the active namespace. The first snapshot is converted into a first data-less snapshot. A snapshot difference operation is preformed between the first data-less snapshot and the second snapshot. First and second point-in-time copies of the first and second working frozen copies are generated in the shared protection namespace. The first point-in-time copy includes the first files extracted from the first working frozen copy and stacked in at least one first horizontal file. The second point-in-time copy includes the second files stacked in at least one second horizontal file. A retention lock is applied to the at least one first and second horizontal files.

Embodiments for a system and method for secure authentication of backup clients in a way that eliminates the need to create users for backup client authentication anywhere in the backup ecosystem, and which eliminates the need for credentials, such as passwords that need protection, updating and synchronization. Such embodiments use a short-term token, such as a JSON web token, for both client and server authentication within the system, and verifies that the tokens grant access using the public key corresponding to the private key assigned to the directory objects by the creator of the directory objects.

System and method for secure authentication of backup clients using short-term tokens

Described is a system and method that provides a data protection risk assessment for the overall functioning of a backup and recovery system. Accordingly, the system may provide a single overall risk assessment score that provide an operator with an 'at-a-glance' overview of the entire system. Moreover, the system may account for changes that occur over time based on leveraging statistical methods to automatically generate assessment scores for various components (e.g. application, server, network, load, etc.). In order to determine a risk assessment score, the system may utilize a predictive model based on historical data. Accordingly, residual values for newly observed data may be determined using the predictive model and the system may identify potentially anomalous or high risk indicators.

Precomputed similarity index of files in data protection systems with neural network

An apparatus for upgrading a software product is provided. The apparatus generates an upgrade package of the software product, the upgrade package including an installation file of the software product, a metadata file and one or more executable files. The apparatus also executes the one or more executable files to perform operations for upgrading the software product. The operations include unpacking the installation file; adding a disk file in the installation file to a virtual machine based on a file name indicated in the metadata file, the disk file including upgraded files of the software product; mounting the disk file to a mount point of the virtual machine, wherein the mount point is indicated in the metadata file; and providing a path to access the upgraded files based on the mount point and a folder path of the upgraded files indicated in the metadata file.

Upgrade of a software product

Systems, methods, and apparatus for authenticating and authorizing clients. A client certificate is used to authenticate and authorize a client (or user). When the client certificate is received, the certificate is authenticated. If the certificate is valid, a username included in the certificate is used to authorize the client. This may be done based on privileges or permissions associated with the user name. Once the client or user is authenticated and authorized, operations requested by the client can be performed as long as permitted by the privileges or permissions.

Web client authentication and authorization

A computer program product, system, and method for generating coded fragments comprises determining a set of available data protection plans; determining one or more parameters associated with a customer, a host, or a data protection system; generating a recommended host protection configuration for the host using the parameters, wherein the recommended host protection configuration includes one or more of the available data protection plans; and assigning the recommended host protection configuration to the host.

Automated host data protection configuration

One embodiment is related to a method for testing representational state transfer (REST) application program interfaces (APIs), comprising: parsing service specification files; prompting, based on the service specification files, a user to select a resource to be tested and to provide relevant request payload field inputs; receiving resource selection and request payload field inputs from the user; converting the request payload field inputs into JavaScript Object Notation (JSON) and/or Extended Markup Language (XML) data; submitting the JSON and/or XML data to a web services host with a hypertext transfer protocol (HTTP) REST request; receiving a response from the web services host in a form of JSON and/or XML data; and presenting the response to the user.
