Snapshots#

Snapshots provide quick, point-in-time backups, allowing for roll back to a previous instance in the event of a hardware failure, faulty application upgrade, VM Bluescreens, etc.. Snapshots/restores can be done at various levels: cloud (entire system), tenant, individual virtual machine, NAS volume.



Automated Snapshots#

Snapshots can be automated to take at regularly scheduled intervals using snapshot profiles. A snapshot profile consists of one or more profile periods. Each period determines a frequency for taking a snapshot as well as a retention time. More information about snapshot profiles is available here: Snapshot Profiles (Snapshot Scheduling)



Manual Snapshots#

Snapshots can also be taken manually, with settable expiration. Manual snapshots can be useful for backup (of a VM, volume, or entire system) immediately before a configuration change, upgrade, or maintenance operation.



Cloud (System) Snapshot/Restore#

Cloud Snapshots provide backup of the entire VergeOS system, including all tenants, VMs, networks, and settings.



What can be restored from a Cloud Snapshot?#

A cloud snapshot can be used to restore:

  • Entire VergeOS system
  • Individual VMs (unquiesced)
  • Individual tenants

For information regarding cloud snapshots, see: Cloud Snapshots and Restores



VM Snapshot/Restore#

VM snapshots allow for quiesced snapshotting (requires guest agent) and schedule/retention customizable per individual VM. For related instructions, see: 

VM Snapshots and Restores.



Tenant Snapshot/Restore#

Individual tenants can be restored from the parent's cloud snapshot. For related instructions, see: Tenant Restores

Additionally, each tenant can utilize Cloud Snapshots,  independently within their environments to backup their own systems.



NAS Snapshot/Restore#

Volume snapshots provide for quiesced backup/restore of individual NAS volumes. For related instructions, see:  NAS Volume Snapshots and Restores
