A current retention mode is identified as being one of conservative or aggressive. When the retention mode is identified as aggressive, a check is made as to whether used space on backup storage is below a lower threshold. If the used space is below the lower threshold, a switch is made into the conservative mode. If the used space is above the lower threshold, the aggressive mode is maintained. While in the aggressive mode, a backup chain of a database is selected for pruning, the selected backup chain having a shortest retention term of all backup chains not yet pruned and not being a latest backup chain. Log backups of the database in the selected backup chain are identified. Each log backup that has expired is deleted regardless of dependency of other backups on an expired log backup.

Self-adaptive copy retention management

Embodiments of the present disclosure provide a data backup method, an electronic device and a computer program product. The method provided includes creating a workflow related to a data source, the workflow being configured to generate a copy of the data source or to replicate the copy of the data source to a remote device. The method further includes identifying a dependency of the workflow, the dependency indicating whether the workflow depends on at least one additional workflow related to the data source. The method further includes scheduling the workflow based at least on the identified dependency. According to the embodiments of the present disclosure, by use of a dependency-based scheduling mechanism, the performance of a storage system can be improved, and consumption of resources such as a storage and an internal memory can be reduced.

Data backup method, electronic device and computer program product

Embodiments of the present disclosure relate to a method, a device and a computer program product for configuring service instances. The method comprises, at a computing device being used to implement a first service instance in a cloud environment, receiving, from a service manager of the cloud environment, a hypervisor related to a configuration of the first service instance. The method further comprises determining, based on the hypervisor, first configuration information for configuring the first service instance. The method further comprises configuring the first service instance with the first configuration information. With this method, service auto-deployment, auto-configuration and auto-association are realized, thereby improving user efficiency of configuring services and user experience.
