Delta Store

The delta store is the key processing engine for Recovery Appliance. A protected database sends only one incremental level 0 backup of each data file to the Recovery Appliance. Following the initial full backup, all backups are highly efficient cumulative incremental backups.

As Recovery Appliance receives incremental backups, it indexes them and stores them in delta pools. Each separate data file backed up to the Recovery Appliance has its own separate delta pool (set of backup blocks). Recovery Appliance automatically manages the delta pools so that it can provide many virtual full backups.
