Spanner Backup Retention

For image-level backups, Veeam Backup for Google Cloud retains restore points for the number of days defined in backup scheduling settings as described in section Creating Spanner Policies.

The forever forward incremental backup method is not implemented for Cloud Spanner instances — during every backup session Veeam Backup for Google Cloud creates a full backup in the regular backup chain. If Veeam Backup for Google Cloud detects an outdated restore point in a backup repository, it removes this restore point from the backup chain.
