Embodiments of the present application relate to the technical field of computers, and provide a firmware upgrade method, an electronic device, a storage medium, and a product. The method comprises: in response to a received firmware upgrade task, uploading a target firmware upgrade file and key information of a baseboard management controller in a target cluster to a master node; screening for candidate network file system nodes and non-candidate network file system nodes for connectivity testing; on the basis of the result of the connectivity testing, determining a network file system configuration node from the candidate network file system nodes, and determining a mounted child node of the network file system configuration node from the non-candidate network file system nodes; copying the target firmware upgrade file from the master node to the network file system configuration node, and copying the target firmware upgrade file to the mounted child node by means of the network file system configuration node; and executing the firmware upgrade task. In the present embodiments, the time and effort of operation and maintenance personnel are saved.

This invention discloses a data synchronization method and related components for a distributed file system, relating to the field of data replication. The method includes acquiring a file replication packet sent by the master end, wherein the file replication packet includes the file content and metadata information of files under each inode of the distributed file system. Then, each file content is copied to a corresponding copy file on the slave end. Furthermore, the basic attributes of the copied files are set to the metadata information corresponding to the file content stored within the copied files. Therefore, this application, when synchronizing files from the master end to the slave end, not only copies the file content but also the file attributes, i.e., the metadata information. Thus, there is no need to manually set file attributes for the copied files on the slave end, improving the reliability and efficiency of data replication.

The application provides a method, system, device and storage medium for disabling remote login of a root account, the method comprising: modifying a remote login configuration file of the root account to reject remote login of the root account; modifying UID and GID of an icfs account to modify the authority of the icfs account to a normal account, and modifying a login file of the icfs account to allow remote login of the icfs account; copying an environment file under a root account directory to an icfs account directory, and modifying the environment file to adapt to the icfs account; and setting the icfs account to allow use of a process management command and restart an sshd service. The application realizes disabling ssh remote login of a root account of a storage server node, and simultaneously realizes ssh remote login of an icfs account of a storage system.

The invention relates to a backup method and device, a recovery method and device, computer equipment, a readable storage medium and a computer program product. The backup method is applied to an agent side and comprises the following steps: initiating a backup request for a database to be backed up to a storage side; mounting the backup set to a preset backup directory through the access interface information; under the condition that the backup request is the first backup request for the database to be backed up, copying each data file to be backed up in the backup set and a corresponding archiving log to a preset backup directory to complete backup of the database to be backed up; under the condition that the backup request is not the first backup request for the database to be backed up, copying the changed data file to be backed up in the backup set to a preset backup directory to complete backup of the database to be backed up; and after the backup of the database to be backed up is completed, sending backup completion notification information to the storage end. By adopting the method, the data recovery efficiency of the data sharing cluster can be improved.

Embodiments of the present application provide a file backup method, device, equipment and computer program product; the file backup method comprises: obtaining a file write request; in the case that the file write request is a file modification request, determining probability information of the file write request corresponding to a ransom behavior; in the case that the probability information is greater than or equal to a preset threshold, then before performing a write operation based on the file write request, copying a request file corresponding to the file write request to a preset protected directory, wherein the protected directory is located in the kernel. In the present embodiment, since the protected directory is located in the kernel, the access permission of the protected directory is higher than the access request of the file write request, so that in the case of write request operation, the file in the protected directory cannot be written, thereby avoiding the ransom operation on the request file, while ensuring the safety and reliability of the information content, further improving the practicability of the method.
