15. After completing this topic, you will be able to explain the Agent for Hyper-V: Restore flows. Agent for Hyper-V: Restore flows

16. Backup Exec ServerHyper-V ServerInside VM VM Restore from tape 2.A “new” VHD / VHDX file is created 3.The disk blocks are written to the VHD / VHDX file Repeat until done 5.Disk blocks are written to the VHD / VHDX file. 1.Data is read from the tape and sent to the Hyper-V host Repeat until done 4.Read data from incremental backups

17. Backup Exec Server Hyper-V ServerInside VM VM Restore from disk / PDDE 1.A “new” VHD / VHDX file is created 4.Disk blocks are written to the VHD / VHDX file 2.Disk blocks are read from the tail of the chain A disk block is only read / sent once Parent disks will be read as necessary 3.Disk blocks are sent to the Hyper-V host
