i need four disksync backups deleted to free up space on my storage but there is no way to delete them.

devGOD,

At this time, you are unable to delete old backups from DiskSync yourself, however, our Backups team will be more than happy to do so for you. You just need to create a ticket within Orbit or Server Command stating what backups you want deleted and they will handle the rest for you. If you have anymore questions or concerns, feel free to PM me.

Thanks,
