Abstract
Described embodiments provide systems and methods for synchronizing a production volume and a backup volume of a storage system. A first thin volume is created and associated with the production volume. A first replica of the production volume is generated by copying data from the production volume to a replica volume. During the copying, an I/O request to be written to the production volume may be received. Data from the I/O request is written to the first thin volume and data changed due to the I/O request is tracked in metadata associated with the production volume and the first thin volume. A size of the first thin volume is checked, and when the size of the first thin volume is below a threshold, changes from the first thin volume are applied asynchronously to the backup storage.
