New in ZVR 3.5 is the ability for Offsite backup. Offsite backup is basically a copy of a regular replica stored in a safe place for a longer period.
The name ‘Offsite Backup’ can be a bit confusing. The functionality can be compared to NetApp SnapVault. Bascially Offsite Backup is a vault (or backup) for replica’s. The purpose is to make sure the replica can be retrieved over a longer time window.

The regular ZVR replica has a protection of max. 5 days. Offsite backup allows to restore data of up to one year back in time. Offsite backups can be stored on SMB/CIFS shares. Storing offsite backup data in Amazon cloud storage is supported as well using a tool which presents Amazon storage a fileshare over SMB.

The offsite backup is wrapped in a so-called Zerto Backup Package. The package contains a full backup of all virtual machines part of a Zerto Virtual Protection Group. The package is portable. It does not need the exact Zerto Virtual Manager installation of version to be restored.

Mind offsite backup is not a replacement for regular backup software. It does not have deduplication, is not an archiving solution and is not able to recover single files.

Use cases for Offsite backup are:

  • compliance use
  • archiving of test/dev virtual machines. Think about a software company usung VM’s for development
  • 3rd site for storage of backup
  • cost reduction

Tolerant failover means a failover is still regarded succesfull even when some of the  VMs are recovered but cannot be not turned on. Causes for a VM not being able to start could be for example an IP conflict, MAC address conflict or not enough resources in a resource pool.
