Each level has different advantages

5

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

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

10

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

Virtualization simplifies recovery
