Abstract
A method for data storage includes creating first and second copies of a logical volume, such that the first and second copies are represented by respective first and second sets of pointers to physical storage locations in which data used by the copies is stored. Responsively to a corruption of at least part of the data that is used by the first copy, the first copy is restored from the second copy by replacing the first set with the pointers in the second set.
