A method, an electronic device, and a computer program product for storage management are provided. The method includes: acquiring a lock attribute record in a lock attribute record chain from a data protection network for backing up data, data protection servers of the data protection network reaching a consensus on the lock attribute record chain, the lock attribute record including a first attribute value of an attribute of a lock operation, the lock operation being used for preventing a backup of the data stored in a storage server from being tampered with; acquiring, based on the lock attribute record, a second attribute value of the attribute of the lock operation from the storage server; and generating, based on determining that the first attribute value does not match the second attribute value, an alarm indicating that the backup is tampered with. This solution can better prevent data from being tampered with.

Method, electronic device, and computer program product for storage management using blockchain

Embodiments of this disclosure relate to a method, a device and a computer program product for data protection. The method comprises determining objects selected by a user in a set of objects, and automatically generating one or more corresponding filtering conditions according to the objects selected by the user. The method further comprises automatically setting a predetermined protection policy for objects meeting the filtering conditions in the set of objects. In the embodiments of this disclosure, corresponding filtering conditions are automatically generated according to some protected objects selected by a user to form a dynamic filter, without manually setting the filtering conditions by the user, thereby improving the user experience of a data protection system.

Method, device, and computer program product for data protection

The present disclosure relates to a method, apparatus and computer program product for managing an application system. According to example implementations of the present disclosure, there is provided a method for managing an application system. In the method, backup data of the application system are generated in response to receiving a backup request for the application system; abstract information of the backup data is obtained on the basis of a predefined abstract rule; the abstract information is transmitted to a blockchain system associated with the application system so as to store the abstract information to the blockchain system; and the application system is managed on the basis of the blockchain system and the backup data. Further, there is provided an apparatus and computer program product for managing an application system.

Method, apparatus, and computer program product for managing application system

Implementations of the subject matter described herein provide methods and systems of controlling data backup, and a computer readable storage medium. The method comprises: obtaining test data for performing data backup with a plurality of backup solutions, the plurality of backup solutions being associated with each set of values amongst a plurality of sets of values of a plurality of factors affecting the data backup; generating a training sample set based on comparison of the test data; converting the training sample set into a decision model for controlling data backup; and optimizing the decision model based on the configuration parameters obtained by performing data backup with the decision model.

Methods and systems for controlling data backup

A method and system for sharing pre-calculated fingerprints and data chunks amongst storage systems on a cloud local area network. Specifically, the disclosed method and system extend the functionality of data deduplication storage systems to include querying other data deduplication storage systems on the cloud local area network for fingerprints, corresponding to data chunks, when these fingerprints and data chunks are not stored locally. The transfer of data chunks between one data deduplication storage system to another through the cloud local area network may be a faster and cheaper alternative to the transfer of data chunks between a data deduplication storage system and a client through a wide area network.

Method and system for sharing pre-calculated fingerprints and data chunks amongst storage systems on a cloud local area network

Embodiments of the present disclosure provide a method, a device and a computer program for data backup. A method of backing up data comprises: in response to receiving, from an application system, a request for backing up first data, storing the first data into a first backup node; generating first metadata corresponding to the first data, the first metadata comprising first digest information of the first data; storing the first metadata into a block chain system to which the first backup node belongs; and verifying integrity of the first data stored in the first backup node with the first metadata stored in the block chain system. By utilizing a block chain system, the embodiments of the present disclosure ensure that data backed up are protected from being tampered with.
