The system
Records locked on your hardware
Every record is encrypted on your own machines, with an encrypted backup you keep off site. Only you hold the keys, so no outside company can read any of it.
The records live on computers you control, locked so that nobody who finds the drive can read a thing.
A locked backup goes to a drive you keep somewhere safe. If a machine ever fails, you restore onto another one and are running again in minutes.
There is no cloud account that can be shut off and no vendor holding your data. The records are your, in your hands.
