Abstract
An apparatus comprises a processing device configured to determine that a first data structure comprises an indication that a first logical page is an orphan and to obtain the first logical page based at least in part on the determination. The processing device is configured to identify a pointer to a second logical page from a second data structure of the first logical page and to determine a data offset that corresponds to the pointer. The processing device is configured to determine a snapshot group that corresponds to the first logical page and to identify a candidate logical page based at least in part on the data offset, the snapshot group and the pointer. The processing device is configured to determine that the candidate logical page is a match for the first logical page and to link the candidate logical page and the first logical page together.
