ABSTRACT:
Techniques introduced here support block level transmission of a logical container from a network storage controller to a backup system. In accordance with the techniques, transmission can be restarted using checkpoints created at the block level by allowing restarts from various points within a logical container, for example a point at which 10%, 50%, or 75% of the logical container had been transmitted. The transmission can be restarted while maintaining data consistency of the logical container data and included meta-data. Advantageously, changes made prior to a checkpoint restart to, for example, meta-data, do not lead to inconsistent logical container backups.
