Data corruption is the damage of info caused by various hardware or software fails. When a file gets corrupted, it will no longer work as it should, so an application will not start or shall give errors, a text file could be partially or completely unreadable, an archive file will be impossible to open and then unpack, etc. Silent data corruption is the process of info getting damaged without any acknowledgement by the system or an admin, which makes it a significant problem for hosting servers as fails are much more likely to happen on larger in size hard drives where considerable volumes of info are located. When a drive is a part of a RAID and the info on it is duplicated on other drives for redundancy, it is likely that the damaged file will be treated as a regular one and it will be duplicated on all drives, making the harm permanent. Lots of the file systems which run on web servers today often are not able to recognize corrupted files right away or they need time-consuming system checks during which the server isn't functioning.

No Data Corruption & Data Integrity in Cloud Hosting

We guarantee the integrity of the info uploaded in every cloud hosting account which is generated on our cloud platform because we work with the advanced ZFS file system. The latter is the only one that was designed to avoid silent data corruption via a unique checksum for each file. We will store your information on a large number of NVMe drives which work in a RAID, so the same files will be available on several places concurrently. ZFS checks the digital fingerprint of all files on all drives in real time and in case the checksum of any file differs from what it needs to be, the file system replaces that file with an undamaged version from a different drive inside the RAID. There's no other file system which uses checksums, so it is possible for data to get silently damaged and the bad file to be duplicated on all drives over time, but since that can never happen on a server running ZFS, you don't have to worry about the integrity of your data.

No Data Corruption & Data Integrity in Semi-dedicated Servers

Your semi-dedicated server account will be resistant to silent data corruption since all of our storage servers work with the reliable 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 kept on a couple of redundant drives in a RAID i.e. the files shall be the same across all disks. All of the copies of a particular file will feature the same checksum on all hard disks and ZFS will compare the checksums of the duplicates in real time, so if it detects a mismatch, which will indicate that one of the copies is corrupted, it'll swap that file with a good copy from one of the other disks. Even if there is a sudden power loss, the data on the servers will not be corrupted and there won't be any need for a time-consuming system check which other file systems perform after some malfunction, prolonging the time needed for the server to return online. ZFS is the only file system that can truly protect your content from silent data corruption.
