Techniques described herein relate to a method for performing data protection services for limited access cloud data. The method includes obtaining, by a data manager, an initial cloud service provider (CSP) proxy generation request from a user; in response to obtaining the initial (CSP) proxy generation request: creating an authentication account in a CSP directory based on the initial CSP proxy generation request; instantiating a CSP proxy in an on-premises CSP using authentication information associated with the authentication account; storing the authentication information; and associating the user with the authentication information and the CSP proxy, wherein after the associating the CSP proxy can access limited access cloud data and cloud resources of the on-premises CSP.

Method and system for performing authentication and object discovery for on-premises cloud service providers

Embodiments of the invention relate to methods and systems for backing up user defined logical assets. In accordance with one or more embodiments, a user may define a logical asset type prior to a backup being performed. The user may define the logical asset type based on any rules, filters, or attributes of files and/or folders stored in a file system. Once the user has defined the asset type, the system may utilize file-system meta-data to quickly ascertain which files and folders meet the definition of the logical asset type, allowing for the backup of the user defined asset to be performed with minimal additional workload by the production hosts, clients, backup agents, and other associated components of the system.

Attribute based asset discovery for intelligent protection

A method for managing data protection includes initiating, by a backup server, identifying an active directory (AD) application on the VM, wherein the AD application comprises a set of AD objects and a directory service for managing the set of AD objects, in response to identifying the AD application, installing a new AD listener in the production environment, performing listening on the AD application in the production environment to detect changes to the set of AD objects, monitoring, by the backup server, generating a VM backup of the VM and an AD application backup of the AD application, and storing the VM backup and the AD application backup in a backup storage system, based on the VM backup generation, and based on the listening, performing a backup schedule analysis on the backup schedule, and based on the backup schedule analysis, performing a backup schedule modification on the backup schedule.

Active directory object observability for backup policy management in a production environment

Detecting the most recent state of an active directory object and recovering using backups or production tombstones

A method for managing file based backups (FBBs) includes obtaining, by a FBB metadata file operating in a production host and from an application, a shared access request for a plurality of virtual machines (VMs) to access a FBB, accessing a FBB metadata file associated with the FBB to determine file data accessible to the plurality of VMs, performing an attribute analysis on the FBB metadata file, wherein the storage location attributes are each associated with a storage location of a portion of the file data in a backup storage system, generating a shared virtual disk in the production host based on the attribute analysis, wherein the shared virtual disk maps the file data to the storage locations, generating the plurality of VMs, wherein the VMs read from and write to the shared virtual disk, and enabling access to the virtual machines by the application.

Managing use of a shared virtual disk for accessing data in file based backups by multiple virtual machines

Embodiments of the invention relate to generating backups of assets. More specifically, in one or more embodiments of the invention, the meta-data generated during the backups is leveraged for detecting cyber-attacks by leveraging backup meta-data, to reduce the amount of data that needs to be scanned by a cyber-security module to detect a cyber-attack, such as a ransomware attack. This allows any attacks to be detected earlier and reduce processing by leveraging the periodic backups that are performed as part of data protection, to detect when an attack has or is occurring. By making these determinations, a quick identification of possible ransomware attacks may be made and other methods of mitigating the attack may be deployed when the method of mitigating the attack might still be useful to mitigate potential damage to a user's data.

Using backup meta-data and analytics for detecting cyber-attacks

A method for managing virtual machines includes obtaining a backup request for a full backup of a VM, in response to the backup request: performing a logical slicing of VM data associated with the VM to obtain a set of logical slices, storing the set of backup slices in a backup storage system, after storing the set of backup slices, obtaining backup metadata associated with the VM from the backup storage system, performing, using the backup metadata, a slice file system analysis on each backup slice of the set of backup slices associated with the VM to obtain file system information for a portion of VM data stored in each backup slice of the set of backup slices, and generating, from each backup slice associated with the full backup, a file indexing system for each backup slice in the set of backup slices using the file system information.

File system indexing of backup slices for large virtual machines

One or more embodiments of the invention improves upon the traditional method of performing a backup, by having a data protection manager or similar component of the system, determine, when a backup is requested, which backup agent should initially perform the backup. That backup agent may then determine among the other applicable backup agents, which backup types are needed and the order each backup agent performs the backup, when more than one backup agent is appropriate. This will allow for a more efficient backup, while avoiding collisions between two or more backup agents trying to simultaneously back up the same data.

Applications and file system cluster protection

A method for managing the storage of file based backups (FBBs) includes obtaining, by a backup agent operating on a production host environment, a FBB generation request for plurality of assets at a point-in-time, wherein the backup agent is associated with a plurality of backup policies, in response to the FBB generation request: generating a FBB of the plurality of assets, performing an attribute analysis on the FBB metadata file to determine a directory service associated with each of the plurality of assets, obtaining a first sub-asset and a second sub-asset based on the attribute analysis, assigning a backup policy of the plurality of backup policies to each of the two sub-assets, and performing a storage of the FBB based on the backup policies assigned to each of the sub-assets.

Conceptualizing sub-assets of file based backups based on directory service of the assets

Techniques described herein relate to a method for performing generating backups of host data. The method may include obtaining a backup request associated with an asset of the host; obtaining file system metadata associated with the asset from a file system metadata repository; identifying data in a disk of the host associated with the asset based the file system metadata; obtaining file size and cluster size associated with each file of a file system using the file system metadata; making a determination that the actual size and cluster size do not match for at least one file of files of a file system; identifying a difference between the actual size and the cluster size of the at least one file of files; identifying the difference as slacks; generating slack metadata associated with the slacks; and providing slack data and the slack metadata to post processing engines.

Identifying slacks during backup generation for anomaly detection

Techniques described herein relate to a method for enhancing backup and recovery of a VM, including receiving, in connection with a backup operation, a backup-ready metadata database and a backup image of the VM at a backup storage. The method also includes logically splitting, using the backup-ready metadata database, the backup image into multiple logical portions. The method further includes performing a cyber recovery operation on one of the logical portions. In addition, the method includes performing an action from an action set in response to the cyber recovery operation.

Splitting image backups into sub-images

Techniques described herein relate to a method for performing backups of virtual machines on a host. The method includes obtaining an incremental image backup generation request associated with a virtual machine (VM) of the host; writing changed data blocks included in a storage volume associated with the VM to a backup storage; initiating the generation of a virtual synthetic full image backup on the backup storage using the changed data blocks and a previous backup of the VM; obtaining file system metadata associated with the VM; generating post processing metadata by mapping a list of the changed data blocks to file system metadata entries and the corresponding data runs associated with the changed data blocks; writing the post processing metadata with the virtual synthetic full image backup; and initiating post processing on the virtual synthetic full backup using the post processing metadata by post processing engines.

Generating data block mapping in incremental image backups for post processing

A method for information recovery includes receiving a first metadata corresponding to a first batch of files, determining a set of rules for backup locations based on the first metadata, initiating a backup operation of a second batch of files, where the backup operation includes the set of rules, receiving a second metadata corresponding to a first file of the second batch of files, applying the set of rules to the second metadata to identify a first one of the backup locations, and sending the first file to the first one of the backup locations.
