Abstract
Techniques for data synchronization involve obtaining a first bitmap about a first storage device, the first storage device including a group of storage areas, a bit in the first bitmap indicating whether data in a corresponding storage area of a first size in the group of storage areas is to be synchronized to a second storage device. The technique further involves, in response to a configuration of the first storage device being changed, determining a second size of a storage area in the group of storage areas. The technique further involves converting the first bitmap into a second bitmap based on the first size and the second size. In addition, the technique further involves synchronizing data from the first storage device to the second storage device based on the second size and the second bitmap.
