The present disclosure describes systems and methods for aggregation and management of cloud storage among a plurality of providers via file fragmenting to provide increased reliability and security. In one implementation, fragments or blocks may be distributed among a plurality of cloud storage providers, such that no provider retains a complete copy of a file. Accordingly, even if an individual service is compromised, a malicious actor cannot access the data. In another implementation, file fragmenting may be performed in a non-standard method such that file headers and metadata are divided across separate fragments, obfuscating the original file metadata.

Aggregation and management among a plurality of storage providers

The present disclosure describes systems and methods for aggregation and management of cloud storage among a plurality of providers via file fragmenting to provide increased reliability and security. In one implementation, fragments or blocks may be distributed among a plurality of cloud storage providers, such that no provider retains a complete copy of a file. Accordingly, even if an individual service is compromised, a malicious actor cannot access the data. In another implementation, fragments may be duplicated and distributed to multiple providers, such that loss of communications to any one provider does not result in inability to access the data. This implementation may be combined with error correction techniques to allow recovery, even with loss of multiple providers. File synchronization may also be faster in these implementations by dividing reading and writing operations among multiple providers.

Systems and methods for secure file management via an aggregation of cloud storage services

The present disclosure describes systems and methods for aggregation and management of cloud storage among a plurality of providers. In a first aspect, the invention is directed to file distribution and management across multiple cloud services via a storage manager. The storage manager may aggregate third-party cloud storage provider accounts into a single cloud storage space and load balance files among the third party-accounts as necessary. In one implementation, the storage manager may act as an intermediary, and files may be transferred by the client to the storage manager, which may select and forward the files to a third-party storage provider. File retrieval may be performed similarly, with the client requesting a file from the intermediary storage manager, which may retrieve the file from the corresponding third-party storage provider and forward the file to the client device.

Systems and methods for aggregation of cloud storage

The present disclosure describes systems and methods for detection and mitigation of malicious activity regarding user data by a network backup system. In a first aspect, a backup system receiving and deduplicating backup data from a plurality of computing devices may detect, based on changes in uniqueness or shared rates for files, atypical modifications to common files, and may take steps to mitigate any potential attack by maintaining versions of the common files prior to the modifications or locking backup snapshots. In a second aspect, the backup system may monitor file modification behaviors on a single device, relative to practices of an aggregated plurality of devices. Upon detection of potentially malicious modification activity, a previously backed up or synchronized store of data may be locked and/or duplicated, preventing any of the malicious modifications from being transferred to the backup system.

Systems and methods for automatic snapshotting of backups based on malicious modification detection

The present disclosure describes systems and methods for aggregation and management of cloud storage to leverage third-party storage policies. Some cloud storage providers may allow users to store some types of files for free, without counting the files against a storage quota or limit, such as photos. Other providers may allow users to store music files, and may automatically replace lower quality recordings with high quality versions (improving quality for the user while performing deduplication and storage mitigation by the server). These policies may be utilized by a storage manager to direct corresponding types of files to specific storage providers to take advantage of free storage or further processing. The files may be excluded from load balancing algorithms, such that storage quotas are not unbalanced as a result of policies of one provider.

Systems and methods for third-party policy-based file distribution in an aggregation of cloud storage services

The present disclosure describes systems and methods for aggregation and management of cloud storage to leverage processing provided by a cloud provider with aggregation of cloud storage services. Files may be pipelined to the processing provider and then resynchronized to an alternate storage service, with processing or metadata retained. In one implementation, files may be provided for processing, retrieved, and then separately provided for storage. In another implementation, files may be simultaneously provided for processing and storage at different cloud storage providers. After processing, the metadata of the file may be retrieved, and the file deleted from storage of the processing provider. The metadata may be synchronized with the stored file, or may be retained in metadata storage and retrieved by the client device during synchronization or file retrieval operations.
