Data corruption is the damage of info because of various software or hardware failures. After a file is damaged, it will no longer function accurately, so an application will not start or will give errors, a text file will be partially or fully unreadable, an archive will be impossible to open then unpack, etc. Silent data corruption is the process of information getting damaged without any acknowledgement by the system or an admin, that makes it a significant problem for web hosting servers as failures are much more likely to occur on larger in size hard disks where considerable volumes of info are placed. If a drive is part of a RAID and the info on it is replicated on other drives for redundancy, it's more than likely that the damaged file will be treated as an ordinary one and will be duplicated on all of the drives, making the harm permanent. Lots of the file systems which run on web servers today often cannot discover corrupted files right away or they need time-consuming system checks during which the server isn't operational.

No Data Corruption & Data Integrity in Shared Hosting

We have resolved the matter of silent data corruption on our shared hosting servers by using the advanced Z file system, or ZFS. The latter is superior to other file systems as it is the only one out there that checks all files instantly by employing a checksum - a digital identifier that's unique for each file. When you upload content to your account, it will be stored on several NVMe drives and continually synchronized between them for redundancy. ZFS regularly analyzes the checksum of all files and if any file is detected as damaged, it's replaced promptly with a good copy from some other disk. As this happens in real time, there's no risk that a corrupted file may remain or may be copied on the remaining NVMes. ZFS requires lots of physical memory to execute the real-time checks and the advantage of our cloud hosting platform is that we use multiple powerful servers working together. In case you host your websites with us, your info will be intact no matter what.

No Data Corruption & Data Integrity in Semi-dedicated Hosting

Your semi-dedicated hosting account will be protected against silent data corruption since all of our storage servers use the reliable ZFS file system. What makes the aforementioned unique is that it employs checksums, or digital identifiers, in order to verify the integrity of each and every file. When you upload content to your account, it will be placed on a couple of redundant drives working in a RAID i.e. the files will be the same across all drives. All of the copies of a particular file will feature the same checksum on all hard drives and ZFS will compare the checksums of the copies in real time, and if it identifies a mismatch, which would indicate that one of the copies is damaged, it will substitute that file with a healthy copy from one of the other disks. Even if there is a sudden power loss, the data on the servers won't get corrupted and there will not be any need for a time-consuming system check that other file systems perform after some malfunction, lengthening the time needed for the server to get back online. ZFS is the only file system which can really protect your content from silent data corruption.
