In general, embodiments relate to a method for backing up databases, the method includes receiving a backup request, wherein the backup request specifies a role of primary and an asset group identifier for an asset group, identifying, based on the backup request, a database in the asset group, and issuing the backup request for the database.

Scheduling backups on a primary database in a high-availability configuration

Embodiments of the present disclosure relate to a method, an electronic device, and a computer program product for backup. The method includes: determining a plurality of buffer periods associated with a plurality of pending backup operations of a plurality of objects, each buffer period being a preprocessing period for a corresponding pending backup operation. The method further includes: determining a plurality of predicted execution durations of the plurality of pending backup operations based on historical execution durations of respective historical backup operations of the plurality of objects. The method further includes: determining priorities of the plurality of pending backup operations based on the plurality of predicted execution durations and the plurality of buffer periods. The method further includes: executing the plurality of pending backup operations based on the priorities.

Method, electronic device and computer program product for backup

A method, electronic device, and computer-readable medium for storage management is disclosed. The method for storage management includes acquiring a data change rate of a data source, the data change rate indicating an occurrence rate of data to be backed up in the data source. The method also includes acquiring a recovery capability of a backup system to recover backed-up data and determining, based on the data change rate and the recovery capability, a backup strategy for backing up the data to be backed up.

Embodiments of the present disclosure relate to a method, device and computer program product for determining a consistency level of a virtual machine snapshot. The method comprises obtaining a backup log file of the virtual machine snapshot generated in a virtual machine backup process, the backup log file comprising log information related to the generation of the virtual machine snapshot. The method further comprises determining the consistency level of the virtual machine snapshot based on the backup log file, the consistency level indicating a matching degree between a state of a virtual machine represented by the virtual machine snapshot and an actual state of the virtual machine when the virtual machine snapshot is generated.

Method, apparatus, and compute program product for determining consistence level of snapshots of virtual machines

Embodiments of the present disclosure relate to a method for managing backup jobs, an electronic device, and a computer program product. The method includes: determining expected execution durations of a group of to-be-executed backup jobs; dividing the group of to-be-executed backup jobs into a plurality of backup job subsets based on the expected execution durations, wherein a difference between the expected execution durations of every two backup jobs in each backup job subset does not exceed a predetermined threshold duration; and adjusting an execution plan of the group of to-be-executed backup jobs to cause the backup jobs in at least one backup job subset in the plurality of backup job subsets to simultaneously begin to be executed.

A efficient method for long-term retention backup policy within recovery point objectives (RPO). Specifically, the disclosed method proposes a dynamic promotion scheme through which short-term retention backup copies, in compliance with specified long-term retention RPOs, may be promoted to render long-term retention backup copies. Further, the disclosed method not only looks to past and/or presently dated short-term retention backup copies, but also looks to prospective (or future) dated short-term retention backup copies, which are expected or predicted to be produced, for promotion. Moreover, in circumstances where there are no appropriate past, present, or future dated short-term retention backup copies to promote, the disclosed method triggers new backup operations to acquire the long-term retention backup copies necessary to maintain the specified long-retention RPOs.

Efficient method for optimizing long-term retention backup policy within recovery point objectives (RPO)

Embodiments of the present disclosure relate to a method, a device, and a computer program product for determining an execution progress of tasks. The method includes determining, according to a determination that a task is executed, whether historical execution information of the task is available. The method further includes determining the expected execution duration of the task based on the historical execution information of the task according to a determination that the historical execution information of the task is available. The method further includes determining the duration of completed execution for the task based on the time point at which execution of the task begins and the current time point. The method further includes determining the execution progress of the task based on the expected execution duration and the completed execution duration.

A method and system for performing authentication for a backup service provided by a server is provided. The method receives a request for authentication from a client device, the request for authentication including a signature generated using a private key. The method sends a request to obtain a public key corresponding to the private key to the server and receives the public key from the server, the public key being retrieved by the server from a backup of a virtual machine. The method verifies the signature using the public key and generates a token encrypted using the public key, the token enabling the client device to access the server for the backup service. The method sends the token to the client device, the token to be decrypted using the private key by the client device.

Key-based authentication for backup service

Embodiments of the present disclosure provide a method, a device and a computer program product for protecting service security. The method of protecting service security comprises receiving, from a client, a deployment request to deploy a service into a cloud environment, and in response to the deployment request, deploying a service instance corresponding to the service in the cloud environment. The method further comprises setting, based on information specific to the service instance, an initial credential for accessing the service instance, and providing information associated with the initial credential to the client so as to enable the client to derive the initial credential.
