No. This is because Synology Cloud Sync sends the backups to Object Storage in a format that is only readable by the Synology platform and not by Veeam. To recover servers with Cloud IBR, you can either create a Direct to Object Storage backup job in Veeam v12, or add the Synology to a Scale-Out-Backup-Repository (SOBR) that offloads backups to Backblaze, with Veeam v10 or later.
