Abstract
The Source Volume Backup with Predictive and Lookahead Optimizations Apparatuses, Methods and Systems (“SVBAF”) transforms backup request inputs via SVBAF components into backup response outputs. A set of blocks to be copied from a source volume to a target volume is designated based on predictive optimization settings and copied based on lookahead optimization settings while an operating system is configured to write to the source volume. Blocks of the source volume that were written to by the operating system are identified. A determination is made whether to enter a CoW mode. If the CoW mode should not be entered, the designated set of blocks is changed to include at least one of the identified blocks and a pass is repeated. Otherwise, the operating system is instructed to enter the CoW mode and bring the target volume into a state consistent with a state of the source volume.
