In this article provides information on using VMware Changed Blocks Tracking in Xopero ONE.
The Changed Block Tracking (CBT) tool calculates and provides Xopero with the differences between full, differential, and incremental backups; it's a VMware-provided tool that Xopero ONE uses by default. VMware CBT can be enabled in the VMware backup options when creating a backup plan.
If CBT is unavailable or you choose not to use it, you can enable the Xopero ONE Classic Method instead. In this case, the Xopero ONE agent calculates the differences between differential and incremental backup executions.
It is recommended to use the Xopero ONE virtual appliance for VMware backups. If you choose to use the Xopero ONE Classic Method, the agent installed on the virtual appliance will handle the calculation of changes.
The method for calculating changes can be selected from the drop-down list. When VMware CBT (recommended) is selected, you can configure two additional checkboxes:
Enable Change Blocks Tracking in VMware for all virtual machines selected for backup (recommended) — when this option is enabled, CBT will be used for all protected virtual machines.
Reset CBT every full copy — when enabled, CBT will be reset during each full backup. Since CBT leaves markers indicating where the last changes occurred, this option clears those markers to prevent potential issues.
