Various method, system, and computer program product embodiments for performing a backup of a source storage volume to a target storage volume are provided. In one exemplary embodiment, a flashcopy of the source storage volume to the target storage volume is initiated. The content of the source storage volume is stored on the target storage volume in a space efficient manner. The space requirement of the stored content on the target storage volume is monitored. The flashcopy is terminated when the space requirement reaches a predetermined level. The stored content on the target storage volume is copied to a backup storage medium. A new flashcopy of the source storage volume is initiated.

Incremental backup of source to target storage volume

A flashcopy of a source storage volume to a target storage volume is initiated. The content of the source storage volume is stored on the target storage volume in a space efficient manner. The space requirement of the stored content on the target storage volume is monitored. The flashcopy is terminated when the space requirement reaches a predetermined level. The stored content on the target storage volume is copied to a backup storage medium. A new flashcopy of the source storage volume is initiated.

A method, system, and computer program product are provided for maintaining a storage device backup consistency group. The method comprises receiving a first I/O command for a first storage device, receiving a second I/O command for a second storage device, identifying a transaction comprising both the first I/O command and the second I/O command, accessing a storage device backup consistency group for the first storage device, determining whether a backup for the second storage device is a member of the storage device backup consistency group, and performing a predefined corrective action if a backup for the second storage device is not a member of the storage device backup consistency group. The predefined corrective action may comprise detecting or creating a backup for the second storage device and then adding the detected or created backup to the storage device backup consistency group, invalidating the second I/O command, and/or issuing a warning.

Maintaining storage device backup consistency

Provided are a system, method and article of manufacture for validating an expected data output of an application under test. A first table comprising named columns populated with the expected data output and a second table comprising named columns associated with the expected data output of the named columns of the first table are retrieved. The named columns of the first table are compared with the named columns of the second table. An alert is generated in response to detecting a difference between a characteristic of a named column of the first table and a characteristic of a named column of the second table.

Command line testing

A method for adding comments to deleted code includes maintaining a first version of a file in a code repository, providing the first version of a file available to a first user, receiving a second version of the file, the second version being an updated version of the first version of a file, the second version of the file including at least one segment of deleted code and at least one comment regarding the at least one segment of deleted code, simultaneously maintaining the second version of the file and the first version of the file in the code repository, providing the second version of the file to a second user, providing a comparison tool for comparing the first version of the file to the second version of the file, and receiving a modification approval indication including an approval of deletion of the at least one deleted segment.
