Abstract: A method, an electronic device, and a computer program product for storage management are provided. The method includes: acquiring a lock attribute record in a lock attribute record chain from a data protection network for backing up data, data protection servers of the data protection network reaching a consensus on the lock attribute record chain, the lock attribute record including a first attribute value of an attribute of a lock operation, the lock operation being used for preventing a backup of the data stored in a storage server from being tampered with; acquiring, based on the lock attribute record, a second attribute value of the attribute of the lock operation from the storage server; and generating, based on determining that the first attribute value does not match the second attribute value, an alarm indicating that the backup is tampered with. This solution can better prevent data from being tampered with.

Abstract: A multi-function exercise device includes a supporting frame, a pair of linkage members, a first wheel unit, and a second wheel unit. Each of two first coupler bars couples a front link of the respective linkage member to the first wheel unit to permit rotation of the first wheel unit in response to upward movement of the front link of one of the linkage members. Each of two second coupler bars couples a rear link of the respective linkage member to the second wheel unit to permit rotation of the second wheel unit in response to swinging movement of the rear link. Two load-resistance members are provided for retarding rotations of the first and second wheel units, respectively.

Abstract: A treadmill includes a front leg frame and a connecting arm. The front leg frame has a front end pivoted to a support base. The connecting arm has a lower end pivoted to the leg frame. An upper end of the connecting arm is connected to a threaded sleeve connected telescopically to a motor-driven screw rod disposed at a top side of a tread base. A hydraulic telescopic unit is pivoted to the leg frame and the support base. When the threaded sleeve is driven by the screw rod, the tread base is inclined. When the tread base is folded upward, it is held in position by the hydraulic telescopic unit which is prevented from moving telescopically by engagement with a latch member. The latch member disengages the telescopic unit through a release member provided on the tread base.
