A search for “Btrfs petabyte” will show that few, if any users are deploying Btrfs at scale, let alone in production.īy contrast, traditional NAS and SAN vendors like EMC and NetApp do make concerted efforts to provide data integrity guarantees but they do so using proprietary file systems that lock you into their platforms which become quite costly as they scale. Btrfs does aim to deliver many of the features found in OpenZFS but in its current state, Btrfs suffers from space accounting issues, a limited volume manager, and general administrative complexity. They also offer primitive at best snapshotting and rollback options to mitigate human error, and do not facilitate the verifiable importing and exporting of your data. With the exception of Btrfs, none of these components are taking any precautions against bit rot or the damage that can be done by an interrupted write to disk.

To keep costs down, these budget-conscious “black box” solutions typically employ GNU/Linux file systems such as Ext3, Ext4, XFS and Btrfs, and hardware or software RAID for redundancy. Of these, the SoHo NAS and Cloud-based solutions can have quite a bit in common because they’re both focused on delivering commodity products and services. Storage solutions broadly fall into four categories: SoHo NAS systems, Cloud-based solutions, Enterprise NAS and SAN solutions, and Microsoft Storage Server solutions. Let’s examine what the most popular file systems do and don’t do to protect your data, and why every storage solution available from iXsystems uses the OpenZFS file system. From “bit rot” to machine and human error, you can assume that the majority of storage solutions are not taking any data integrity precautions beyond some form of simple redundancy. The countless storage products on the market use a myriad of different “production ready” file systems, and these file systems vary dramatically in the precautions they take to guarantee the integrity of your data.
After all, the file system is the most critical component in doing so. “My data” is a reasonable answer but if you take that data seriously, you should take a moment to think about the actual underlying file system that you are trusting to keep your data safe.
