Hyper-V protection strategy |
Considerations |
---|---|
Hyper-V (host-OS-level) backups |
• Quickest setup, do not need to add VMs individually or install agent on each VM. • Automatically include new VMs in backup schedules. • Rapid disaster recovery of a failed VM. (See Instant recovery for Hyper-V.) • Enable you to take advantage of the Features of Unitrends Hyper-V protection |
Guest-OS-level backups |
• Backup system treats the VM like a physical client. • All backup options are supported, including selection lists, options to exclude at the volume, directory, or file level, and run pre- and post- backup commands. Recommended for VMs where more granular exclusion of data is required. • Provide application and operating system consistent backup and restore. • For SQL, Exchange, Oracle, and SharePoint backups, perform application-level post backup processing, such as log truncation. • Support all SQL database recovery models. Must run guest-OS-level backups for all recovery models other than simple. • Support backup of multi-node SharePoint farms. • Protect VMs configured with shared VHDXs. • Support Windows instant recovery (WIR) to quickly spin up a virtual replica of a failed Windows client. |
