Optimal DIY NAS with Rockstor Linux

Data Security

Rockstor provides security against data loss through different components. For example, you can create snapshots of the installation in the Storage | Snapshot menu and back up your data with automated backups. The System | Scheduled Tasks menu also lets you define fixed periods for when backups expire.

The developers have also thought of the hardware. By default, the operating system switches on the S.M.A.R.T. service – if it is supported by the hardware – to monitor your storage, which preemptively finds hardware defects. If S.M.A.R.T. is enabled, you have the option of going to the Storage | Disks menu to retrieve data or perform tests by clicking on the desired drive and then selecting one of the tabs. A click on the Refresh button at top right executes the desired function in the window (Figure 7).

Rockstor proves to be both a sophisticated and a flexible NAS system for home-built servers, thanks to the use of Docker containers and Btrfs. The simple operating concept and the uncluttered interface go hand in hand with good stability. Thus, Rockstor is highly recommended for use in everyday life. For users who want to rehash no longer used legacy hardware as a central storage system or convert a microserver into a NAS, the free NAS operating system provides an interesting solution.
