Synthetic data generation for backups of block-based storage

摘要

A system and method for generating synthetic data to simulate backing up data between a primary storage system and a protection storage system is presented. In one embodiment, a first track in a set of tracks is selected at random. Having selected a first track, at least a first block in the first track is modified. Subsequently, it is determined, based on a track run probability, whether to modify a second track that is consecutive to the first track or a third track that is selected randomly. Depending on the determination, at least one block is modified at either the second or third track. Other embodiments are also described herein.

主权项

1. A computer-implemented method to generate a synthetic data set, the computer-implemented method implemented by a track selection module and a block selection module executed by a processor, the computer-implemented method comprising:
determine a percentage of a set of tracks to modify; converting the percentage of tracks to an integer amount of tracks; setting a quantity of tracks to modify to the integer value; selecting a first track in the set of tracks from at least one storage unit to modify; modifying at least a first block in the first track; determining, by the track selection module based on a track run probability, whether to modify a second track that is consecutive to the first track in the set of tracks or a third track that is selected randomly; selecting, by the block selection module, at random at least a second block in the second track or a third block in the third track; and modifying the second block or third block.
