ZFS ZIL and SLOG When it comes to writes on a filesystem, there a different kinds. Synchronous – Writes that are made to a filesystem that are only marked as completed and successful once it has actually been written to the physical media. Easily the most advanced file system (feature-wise) currently available. However it is pretty much limited to solaris (and linux/BSD if you are fine using an older version without the latest features, and without any kind of official support from either the people who actually write ZFS OR linux/bsd!). To understand why using ZFS may cost you extra money, we will dig a little bit into ZFS itself. Quick recap of ZFS. The schema above illustrates the architecture of ZFS. There are a few things you should take away from it. The main takeaway of this picture is that your ZFS pool and thus your file system is based on one or more VDEVs.

ZFS snapshot is an inherent feature from the ZFS file system, and often used as a point-in-time copy of the existing ZFS file system tree in memory. Once a snapshot has been triggered, either manually or on schedule (periodic), the file system tree and its metadata in the memory are committed to disk to ensure an updated and consistent state of.

FreeNAS is a powerful storage solution that makes it easy to share movies and music, back up your photos, protect your files and much, much more. Make your life easier by using FreeNAS to build and set up the perfect home storage system that does exactly what you need.

Consolidate Files

Too much stuff? There’s a simple solution for that. Keep all of your files in one place and access them from any of your devices over your home network. Not only does this free up storage space, it saves time and makes it convenient when you need to transfer things across devices. Simply copy your files to a FreeNAS system and set up the proper protocol to access them. That’s it, you’re ready to go. FreeNAS supports sharing protocols for all major operating systems including CIFS/SMB (Windows), AFP (Apple), and NFS (Unix).

Stream Movies and Music

FreeNAS makes it easy to stream and share your movies and music with your family on any number of devices. Watch a movie on your TV then finish it on your laptop upstairs. FreeNAS does not restrict the number of users that can access your data. When you have friends over for movie night, set up permissions and groups so authorized users can only access the files you allow them to.

Back Up Everything

With FreeNAS, there are no storage quotas or bandwidth caps. The only limit is your own hardware. Local and remote backups can be made with just a few clicks. Replicate a snapshot to an offsite FreeNAS system to create a complete copy of your file system there. Checksums ensure only error-free data gets written to disk and the self-healing file system can repair silent bitrot as long as a redundant copy of the file exists on the system.

Protect Your Data

FreeNAS is designed to protect your files with enterprise-level security features. Unlike proprietary file sharing services, your files are NEVER shared with or stored on a third-party server.

FreeNAS is the first and only open source storage OS to offer encryption on ZFS volumes. Encrypted volumes can only be read by a FreeNAS system with the master key, which you can change at any time. An optional password can be added to protect the entire system from unauthorized access. If you are unfortunate enough to encounter malware, simply roll back to an uninfected state using a saved snapshot. Recovery takes minutes, not days.

More than Just Storage

Plugins allow you to use your FreeNAS system for so much more than just data storage. Create the ultimate entertainment device using the Plex plugin, set up a personal cloud with Owncloud, or host your own Minecraft server—the possibilities are limitless.
Don’t see a plugin for the software you want? No problem. Advanced users can use the FreeBSD package tool to install any software they want.
