Abstract: Writers on a host and associated with a copy service are identified. The identification includes names of the writers and writer types as being system or application writers. For each writer identified as a system writer, a size of the system writer is calculated and a check is made as to whether a volume associated with the system writer includes system data. When the volume include system data, the volume is marked as a critical volume and a size of the critical volume is obtained. A tally is maintained summing the sizes of the system writer and critical volume.

Abstract: Techniques described herein relate to a method for performing data protection services for limited access cloud data. The method includes identifying, by a cloud service provider (CSP) proxy, a protection policy event associated with an incremental approximation backup of an object; in response to identifying the protection policy event: obtaining previous object metadata associated with the object; obtaining object data from on-premises cloud resources associated with the object; generating slices of the object data; generating current checksums and current object metadata associated with each slice; selecting a first slice of the slices; making a first determination that a first current checksum of the current checksums and a first previous checksum associated with the first slice do not match; in response to the first determination: storing the first slice in a backup storage; and updating a first portion of the current object metadata associated with the first slice.

Abstract: 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.

Abstract: Communications are exchanged with a copy service of a host to identify writers associated with the copy service. The identification includes a type of a writer as being a system or application writer. Writers identified as system writers are added to a list of writers that should participate in a backup operation. For writers identified as application writers, components of an application writer are iterated through to determine whether a component of the application writer has a name or logical path that includes a name of a system service. When any component has the name or logical path that includes the name of the system service, the application writer is promoted to be of type system writer by adding the application writer to the list of writers that should participate in the backup operation. Components of each writer listed in the list of writers are backed up.

Abstract: A target host is booted into a preinstallation environment. A request to register as a recovery agent is issued from a REST API of the target host to a backup management server. A TLS certificate to establish a secure channel is received from the backup management server. A request identifying a backup copy to be stored on the target host is issued from the REST API of the target host and over the secure channel to the backup management server. Credentials required to access a backup storage at which the backup copy is stored is received. Using the credentials, the backup copy is retrieved from the backup storage.

Abstract: Writers participating in a backup are identified. A mapping is generated between the writers and associated files. The mapping includes file properties. The mapping is initialized by tagging the writers with a full backup tag. A base backup copy of the writers is created by conducting a full backup of each writer tagged with the full backup tag. At a current backup operation after creating the base backup, a list of current files that will participate in the current backup operation is generated. The list of current files is compared against the files in the mapping to determine whether a particular writer associated with a current file should be tagged with the full backup tag or an incremental backup tag. The particular writer is tagged with the incremental backup tag when file properties associated with the current file have changed.

Abstract: A data structure is generated to store information about a set of writers associated with a copy service. The information is gathered from the copy service and populated into the data structure. The information includes names of the writers, writer types as being system or application writers, and system writer subtypes as being one of bare metal recovery (BMR) writers or system state recovery (SSR) writers. The data structure is reviewed to determine whether a particular writer should participate in the backup. Based on the review, a list is generated including a subset of the participating writers. Instructions are issued, via the copy service, for the writers in the list to prepare for creation of a snapshot. Upon creation of the snapshot, data is backed up from the snapshot to secondary storage.

Abstract: Techniques described herein relate to a method for performing data protection services for limited access cloud data. The method includes identifying, by a cloud service provider (CSP) proxy, a backup generation event associated with a virtual machine (VM); in response to identifying the backup generation event: obtaining VM information associated with the VM; instantiating a VM agent within the VM; obtaining a metadata file from the VM agent; obtaining VM data from limited access cloud data; storing the VM data and a copy of the metadata file in a backup storage to generate a backup of the VM; generating indexing metadata associated with the backup using the metadata file; and providing the indexing metadata to a data manager.
