5 DIY Self Hosted NAS Storage Server For Small Business And Enterprise

Updated: April 7, 2019 / Home » Desktop Computer Software » Data Recovery and Backup Software

The problem with a growing startups or small business is scalability when they reach a path where they are neither small nor big, too big to use public cloud storage services and too small to afford enterprise storage solutions. Public cloud storage services start out cheap but could become prohibitively expensive as more data is stored. Depending on factors outside your control, performance can be unreliable, at the same time there is a high privacy and security risk involved with storing certain data on someone else’s ‘cloud’ computer unless you pay a premium for enterprise military grade encryption.

FreeNAS is used everywhere, for the home, small business, and the enterprise.

  • Web Interface – The Web Interface simplifies administrative tasks. Every aspect of a FreeNAS system can be managed from a Web Interface.
  • File Sharing – SMB/CIFS (Windows File shares), NFS (Unix File shares) and AFP (Apple File Shares), FTP, iSCSI (block sharing), and more.
  • Snapshots – Snapshots of the entire filesystem can be made and saved at any time. Access files as they were when the snapshot was made.
  • Replication – Employ the Replication feature to send Snapshots over the network to another system for true offsite disaster recovery.
  • Encryption – FreeNAS is the first and only open source project to offer encryption on ZFS volumes! A full-volume encryption option is available during volume creation, providing industry standard AES-XTS encryption which can be hardware-accelerated (when the processor has AES-NI capability).
  • Replication – ZFS Snapshots are more than just local backups – they can be used to create remote backups as well. Replicating snapshots of the filesystem to a remote ZFS filesystem creates a complete duplicate there.
