One example method includes performing delta operations to protect data. A delta queue is provided that allows a replica volume to be rolled forwards and backwards in time. When rolling the replica volume forward, an undo delta is created such that the replica volume can be moved backwards after being moved forward. When rolling the replica volume backwards, a forward delta is created such that the replica volume can be moved forwards after being moved backwards.

Near continuous data protection without using snapshots

Redistributing disks based on disk wear patterns is disclosed. The wear patterns of disk drives in a storage system are learned or determined. When a restore operation is performed, the volumes to disk drive mappings are changed to balance the overall wear pattern of the storage system. This insures that, after the restore operation, disks that had comparatively lower wear levels are used more heavily while disks that had comparatively higher wear levels are used less heavily.

Redistribution of disks based on disk wear patterns

Methods and systems for managing data collection in a distributed system are disclosed. To manage data collection, the system may include a data aggregator and a data collector. The data aggregator and may utilize an inference model to predict data based on future measurements performed by data collectors throughout a distributed system without having access to the measurements. The data collectors may be mobile, and the data aggregator may direct the data collectors to various locations. To select paths for the data collectors to follow, the aggregator may utilize the level of uncertainty in predictions, the sensitivities in ranges of data to downstream consumers of the data collected by the data collectors, and/or other types of information. The data aggregator may select the paths for varying goals over time.

System and method for reduction of data transmission in dynamic systems

Methods and systems for managing data collection are disclosed. To manage data collection, a system may include a data aggregator and data collectors. The data aggregator may utilize an inference model to predict the future operation of data collectors, and a pattern selection model to sample data from data collectors at a specific frequency and sequence. The pattern may specify that some data collectors are not to be sampled at various points in time. By doing so, the system may be able to transmit less data, consume less network bandwidth, and consume less energy throughout a distributed system while still providing access to aggregated data.

System and method for reduction of data transmission by information control with reinforced learning

An air-gapped computer receives, from a simplex communication input device, an encoded message communicated by a simplex communication output device. The air-gapped computer system can use a private key to decrypt an encrypted message which was encrypted by a corresponding public key. The air-gapped computer system decodes the encoded message. The air-gapped computer system verifies that the decoded message indicates that a required number of approvers have approved of a user executing a command. The air-gapped computer system extracts the approved command from the decoded message. The air-gapped computer system enables execution of the command by executing the command, or by providing the user with an access token which enables the user to physically access the air-gapped computer system and execute the command.

Executing commands on air-gapped computer systems

Providing content-based sensitivity classification to content data in a data processing system, by defining sensitivity designations for data objects stored in the system, and creating datasets by grouping metadata for data objects that are intended to classified with a same sensitivity designation, wherein each dataset spans multiple storage devices of different storage types, and wherein each dataset defines a single data sensitivity unit for the data objects referenced by a respective dataset. A sensitivity classifier component tags each dataset with a sensitivity tag to specify a protection or control operation on the data objects referenced by the respective dataset, and a processing component then processes data objects for each tagged dataset in accordance with the specified protection or control operation.

Data sensitivity classification using content-based datasets

A system can determine that there is a failed configuration in a microservices architecture, wherein the microservices architecture comprises a group of microservices. The system can order the microservices of the group to produce an ordered group of microservices, wherein the ordering first comprises failed microservices of the group of microservices, then dependent microservices of the group of microservices, and wherein respective failed microservices of the failed microservices depend on respective dependent microservices of the dependent microservices. The system can perform iterations of, splitting the ordered group of microservices into two subgroups of microservices, and reverting changes to one of the two subgroups of microservices. The system can determine that a microservice of the group of microservices has the failed configuration based on a result of the performing of the iterations.

Detecting configuration issues during pre-canary deployment

Disk drive reallocation or replacement is disclosed. When performing a data protection operation, a health score is determined for each of the disk drives associated with the data protection operation. Replacement is recommended for each of the disk drives with an unfavorable health score. The recommendation may also identify a drive class based in part on the write or wear pattern. This allows unhealthy drives to be replaced prior to performing the data protection operation.

Re-allocation of disks based on disk health prior to restore

A system for providing data protection services for data hosted by composed information handling systems includes a system includes a system control processor manager. The manager obtains a data protection architecture; identifies, based on the data protection architecture, first computing resources for a first pool that provides a first set of functionalities of the data protection services; identifies, based on the data protection architecture, second computing resources for a second pool that provides a second set of functionalities of the data protection services; assigns, based on hardware components of the first computing resources, a portion of the first set of functionalities to a first portion of the first computing resources; assigns, based on the hardware components of the first computing resources, a second portion of the first set of functionalities to a second portion of the first computing resources; and instantiates, based on the assignments, the data protection architecture.

Compressing files is disclosed. An input file to be compressed is first aligned. Aligning the file includes splitting the file into sequences that can be aligned. The result is a compression matrix, where each row of the matrix corresponds to part of the file. The compression matrix may also serve as a warm start if additional compression is desired. Compression may be performed in stages, where an initial compression matrix is generated in a first stage using larger letter sizes for alignment and then a second compression stage is performed using smaller letter sizes. A consensus sequence id determined from the compression matrix. Using the consensus sequence, pointer pairs are generated. Each pointer pair identifies a subsequence of the consensus matrix. The compressed file includes the pointer pairs and the consensus sequence.

Warm start file compression using sequence alignment

One example method includes receiving backup requests, creating a respective bitmap fragment for each backup request, each bitmap fragment corresponding to a respective tracking start time, for one of the requested backups, identifying a group of bitmap fragments that correspond to at timeframe extending from a time at which a previous backup was requested to a time at which the particular backup was requested, using the bitmap fragments of the group to create a consolidated bitmap that includes all changes to data in a volume resulting from IOs during the timeframe, with the consolidated bitmap, reading the data from the volume and transmit the data to a recipient, identifying new write IOs, received in parallel with transmission of the data, that are directed to data included in the particular backup, and reading, from the volume, the data to which the new write IOs are directed, and temporarily storing that data.

Efficient multiple concurrent backup LWD filter

One example method includes, in connection with receipt of a backup request, using a consolidated bitmap, that is associated either with multiple bitmap fragments or with multiple backup streams, to read data from a volume and transmitting the data to a recipient, identifying new write IOs, received in parallel with transmission of the data, that are directed to data included in the backup request, reading from the volume, only once, the data to which the new write IOs are directed, writing the data read from the volume to multiple temporary logs, where each of the temporary logs is associated either with a respective one of the bitmap fragments, or with a respective one of the multiple backup streams, and transmitting the data from the temporary log to the recipient, wherein the transmitted data comprises the backup.

One example method includes encoding data as a polysaccharide structure, synthesizing the polysaccharide structure to create polysaccharide storage media that comprises the data, and storing the polysaccharide storage media. The example method may also include receiving a read request directed to the polysaccharide storage media, mapping the polysaccharide structure to create a map in response to the read request, traversing the map of the polysaccharide structure to determine an X-base number, and obtaining the data by converting the X-base number to a binary form.

Polysaccharide archival storage

One example method includes receiving, at an IO journal, a new entry that identifies a respective disk location L, and data X written at that disk location L, and determining whether a location specified in an oldest entry of the IO journal is specified in any other entries in the IO journal. When the location specified in the oldest entry is not specified in any other entries in the IO journal, adding the new entry to the IO journal, and augmenting the new entry with undo data. Or, when the location specified in the oldest entry is specified in at least one other entry in the journal, setting data specified in the oldest entry as undo data for the next entry that identifies that location, and adding the new entry to the IO journal, and deleting the oldest entry from the IO journal.

Methods and systems for managing inference models are disclosed. An inference model may be divided into any number of sub-network units and each sub-network unit of the sub-network units may be located in a different geographical location. Data privacy regulations may apply to the geographical locations. Therefore, a first sub-network unit may be subject to a first data privacy regulation and a third sub-network unit may be subject to a second data privacy regulation. If an output of a sub-network unit is not usable by a downstream sub-network unit due to differences in data privacy regulations, the first sub-network unit may be replaced with a second sub-network unit, the second sub-network unit generating an output that does meet the data privacy regulations of the downstream sub-network unit. Doing so may reduce interruptions to inference generation by the inference model.
