Data corruption is the damage of information due to various hardware or software problems. Once a file gets damaged, it will no longer work accurately, so an app will not start or will give errors, a text file could be partially or fully unreadable, an archive file will be impossible to open then unpack, etc. Silent data corruption is the process of info getting damaged without any acknowledgement by the system or an administrator, which makes it a significant problem for web hosting servers as failures are much more likely to happen on bigger hard drives where significant volumes of information are placed. If a drive is a part of a RAID and the info on it is copied on other drives for redundancy, it is more than likely that the bad file will be treated as a good one and will be duplicated on all drives, making the damage permanent. Lots of the file systems which run on web servers these days often are unable to find corrupted files instantly or they need time-consuming system checks during which the server is not working.
No Data Corruption & Data Integrity in Website Hosting
We guarantee the integrity of the info uploaded in every website hosting account which is made on our cloud platform because we work with the advanced ZFS file system. The latter is the only one that was designed to prevent silent data corruption through a unique checksum for every single file. We'll store your data on multiple NVMe drives which operate in a RAID, so identical files will be present on several places concurrently. ZFS checks the digital fingerprint of all the files on all the drives in real time and in the event that the checksum of any file differs from what it should be, the file system replaces that file with an undamaged copy from a different drive in the RAID. There's no other file system which uses checksums, so it is easy for data to get silently corrupted and the bad file to be reproduced on all drives over time, but since this can never happen on a server running ZFS, you do not have to worry about the integrity of your info.
No Data Corruption & Data Integrity in Semi-dedicated Servers
Your semi-dedicated server account will be shielded from silent data corruption since all our storage servers use the innovative ZFS file system. What makes the latter unique is that it employs checksums, or digital identifiers, so as to guarantee the integrity of every single file. When you upload content to your account, it'll be stored on a couple of redundant drives being employed in a RAID i.e. the files shall be the same on all drives. All the copies of a specific file will feature the same checksum on all hard disks and ZFS will compare the checksums of the copies in real time, so if it identifies a mismatch, which will indicate that one of the copies is corrupted, it'll substitute that file with a healthy copy from one of the other disks. Even if there's an unforeseen power failure, the data on the servers will not become corrupted and there won't be any need for a time-consuming system check which other file systems perform following some failure, lengthening the time needed for the server to return online. ZFS is the only file system that can really protect your content from silent data corruption.
