- Barebone setup on hardware
For an imprtant server, use enterprise class SSDs as bootdisk ex a small Intel S3500
If you use other services beside storage, you should care about disaster backup and restore on problems.
For a pure filer OS setup and pool import and save/restore of napp-it settings in /var/web-gui/_log/* is enough to restore in case of a crash.

- Napp-In-One- This is a universal method with a very short time to regain any server service on problems.
This solution is based on the type-1 hypervisor ESXi. This is not a full size OS, more a bios extension that is installed or reinstalled within minutes as it offers only options to create, edit or import VMs. The performance of ESXi is unique for any sort of guest like BSD, Linux, OSX, Solaris or Windows. You add VMs for any services. Napp-in-One is the base VM. Napp-in-One offers shared ZFS storage and nothing else as it runs on unsecure VMFS storage. Napp-in-One as an ova template is installed or reinstalled ready to use within 5 minutes. All other server or serveices are VMs on ZFS (via NFS from napp-in-one).. This gives you ZFS security, versioning, cache, and online replikation. You can import VMs in current state or a previous version locally or on any other ESXi server. The lokal ESXi profits from fast local storage in software over the local vswitch without a dependence of fast or any network cabling or switches, https://napp-it.org/doc/downloads/napp-in-one.pdf
- Clone bootdisk
You can use a disk copy station or CloneZilla to clone disks to identical discs
This is an option for distribution.
- System Recovery
Save your current bootenvironment per ZFS replication to your data pool.
For recovery, reinstall the OS, restore the bootenvironment and activate it - reboot.
