Each level has different advantages
Traditional restore methods
Virtualization provides greater flexibility

Backup
Traditional methods more complicated and
require resources
Complicated restores require like hardware
for image recovery
File level backups require application
configuration
Traditional file level restores
Traditional backups work inside OS Most virtualization backup applications use image
backups With an image backup, how are individual files
restored?

Virtualization file level restores Image-level backups can mount a virtual disk No agent on target server, so process is different No need to restore entire VM Process is different for virtualization, result the same

Bare-metal restores do not require an OS present

Virtualization bare-metal restores
VM imageBackup
Register a VM
Whole VM is backed up at the image level as a single file Hardware compatibility issues removed with virtualization VMs all have the same virtual hardware VMs can be restored to alternate locations Isolation easy when restoring VMs
Traditional application level restores
Typically restoring to original location Not individual files, but one large file with many objects Limited awareness to file structure Agent or native restores

Copying objects from backup to source can be complicated
Need application objects and restore to source Virtualization makes restoring applications easier No need for dedicated hardware
