Xen Orchestra 5.33

Key Delta backup

Delta backup is one of the most used features in Xen Orchestra. Currently, when creating a Delta Backup Job, the first time the job runs, it does a Full backup and all the following runs will be delta. This is a perfect method to consume less bandwidth and space on your remote.

One of the biggest risks associated with Delta Backup is related to chain corruption. If an undetected issue occurs on any of the exports, this will corrupt the entire backup chain and you won't be able to restore as expected.

This is the reason we introduced the Key backup for Delta Backup in Xen Orchestra. This features gives you the opportunity to do a full backup once in a while within your delta backup job. This will consume a bit more space on your SR, but will reduce the chain corruption risk.


To configure this in your appliance, you need to set a Full Delta backup interval in the advanced settings of your jobs. This is the interval that full key backups will be performed.

Metadata restore option

In Xen Orchestra 5.32 we released the new ability to backup your pools metadata. As announced in the last release, you have now the ability to restore (and delete) your metadata backup.

Patching system rewrite

The patching system in Xen Orchestra has been rewritten from scratch to offer more flexibility and stability.
