Data corruption is the damage of information because of various hardware or software problems. The moment a file is damaged, it will no longer function accurately, so an application will not start or will give errors, a text file could be partially or fully unreadable, an archive file will be impossible to open and then unpack, etc. Silent data corruption is the process of information getting harmed without any identification by the system or an admin, that makes it a significant problem for web hosting servers as failures are very likely to occur on larger in size hard disk drives where significant volumes of information are stored. If a drive is a part of a RAID and the information on it is copied on other drives for redundancy, it's likely that the bad file will be treated as a good one and will be copied on all of the drives, making the harm permanent. A huge number of the file systems that operate on web servers today often are unable to discover corrupted files instantly or they need time-consuming system checks during which the server isn't working.

No Data Corruption & Data Integrity in Web Hosting

We have resolved the problem of silent data corruption on our web hosting servers by using the modern Z file system, or ZFS. The latter is more advanced than other file systems as it is the only one on the market that checks all of the files instantly by employing a checksum - a digital identifier that's unique for each file. When you upload content to your account, it'll be stored on several NVMe drives and continually synchronized between them for redundancy. ZFS regularly compares the checksum of all files and in the event that any file is detected as damaged, it's replaced quickly 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 perform the real-time checks and the advantage of our cloud hosting platform is that we take advantage of multiple powerful servers working together. If you host your sites with us, your information will be intact no matter what.

No Data Corruption & Data Integrity in Semi-dedicated Servers

You won't experience any kind of silent data corruption issues should you buy one of our semi-dedicated server plans as the ZFS file system that we take advantage of on our cloud hosting platform uses checksums in order to ensure that all of the files are intact at all times. A checksum is a unique digital fingerprint which is given to each and every file kept on a server. Due to the fact that we store all content on multiple drives simultaneously, the same file uses the same checksum on all the drives and what ZFS does is that it compares the checksums between the different drives right away. If it detects that a file is corrupted and its checksum is different from what it has to be, it replaces that file with a healthy copy right away, avoiding any possibility of the corrupted copy to be synchronized on the other hard disks. ZFS is the only file system you can find that uses checksums, which makes it far superior to other file systems that cannot detect silent data corruption and copy bad files across hard drives.
