Abstract: The present disclosure relates to data anonymization methods, apparatuses, and storage systems. In one example method, a storage system obtains a data access request, obtains target data based on the data access request, and performs anonymization processing on the target data to obtain anonymized target data. Then, the storage system sends the anonymized target data.

Abstract: A data processing method includes receiving an infection detection request sent by the detection device; obtaining, based on the infection detection request, a data feature obtained by performing feature extraction on target data; and outputting, to the detection device, the data feature for detecting whether the target data is infected by a virus.

Abstract: Embodiments of this application disclose a method for detecting a backup file and a related device. The method includes: obtaining an encryption heatmap of each of a plurality of backup files; determining an encryption score of the backup file based on distribution of a target color in the encryption heatmap; constructing a sequence from the encryption score of each backup file, and performing sampling on the sequence by using a sliding window, to obtain a plurality of subsequences; and performing time sequence anomaly detection on the plurality of subsequences, and determining that a backup file corresponding to an encryption score in an abnormal subsequence is ransomware-encrypted. In this way, it can be detected, without parsing the backup file, whether the backup file is ransomware-encrypted.

Abstract: A computer device creates a first snapshot of a storage system at a first moment at which an abnormal operation behavior for the storage system is detected; creates a second snapshot of the storage system at a second moment at which it is determined that the storage system meets an attack detection condition; and then determines, based on a result of comparison between the first snapshot and the second snapshot and data content of one or more groups of operation abnormality data generated by the storage system between the first moment and the second moment, whether the storage system is attacked by ransomware.

Abstract: A storage device stores a data copy in a form of a data backup chain. The data backup chain records data copies in the storage device in a time sequence of backing up the data copies to the storage device. Any data access instance has a data access function, and the data access instance can process a data access request. The data access instance may perform a data backup, and back up data in storage space of the data access instance to the storage device as a data copy in the data backup chain. With support of the storage device, the data access instance further has a data disaster recovery function and a data tiering function.

Abstract: This application provides a data backup system and an apparatus. The system includes a data processing apparatus and a storage device. The data processing apparatus is configured to receive a write request sent by a first host, where the write request carries first data that needs to be backed up to the storage device. The data processing apparatus is configured to perform deduplication and compression operations on the first data, to obtain second data. The data processing apparatus is further configured to write the second data into the storage device.

Abstract: A data processing method includes a computing device that obtains first data, and determines a deduplication rate of the first data and a working status of the computing device. When the working status of the computing device is a busy state, and when the deduplication rate of the first data is greater than or equal to a first preset value, deduplication on the first data is performed. When the deduplication rate of the first data is lower than the first preset value, deduplication is not performed on the first data, and the first data may be directly stored.

In one example method, a storage system obtains a data access request, obtains target data based on the data access request, and performs anonymization processing on the target data to obtain anonymized target data.
