CA ARCserve D2D lets you perform frequent and periodic block level backups of your full machine. These backups can be stored on either an internal drive, an external drive, or on a remote network share. To avoid a continuous and never-ending backup cycle, the volume being backed up cannot be specified as the backup destination. CA ARCserve D2D provides the capability to perform Full, Incremental, or Verify type backups.
The basic process for how CA ARCserve D2D works is simple. When you initiate a backup (either as scheduled or manually launched), CA ARCserve D2D captures full VSS snapshot, and then backs up only blocks that has been changed from previous successful backup. During this block-level backup process, CA ARCserve D2D not only captures the data, but also creates a catalog containing all information related to the operating system, installed applications (Microsoft SQL and Microsoft Exchange only), configuration settings, necessary drivers, and so on. When required, you can then restore this backed-up image to recover your data or your entire machine.
