Snapshots – Recovering Data Snapshot created at 10:00 AM This report Is due This report Is due File is recovered at 10:12 AM The file is recovered from the snapshot image created at 10:00 AM and in that time the user made some changes. However, the majority of the report is the same. File is accidentally deleted at 10:10 AM This report Is due today

  43. 43. FalconStor ‘Disk Safe Agents’ Real time, continuous client / server disk protection
  44. 44. Disk Safe Agents for Continuous Data Protection Disk Safe agent software resides on client and server disks the customer wants to protect. As a protected disk is written to, the agent simultaneously sends the written data to the iSCSI Brick Should a protected disk fail completely, the disk can be replaced, the system PXE booted, and the entire disk recovered. PROTECTED!!! PROTECTED!!! PROTECTED!!! PROTECTED!!!
