Data corruption is the damage of data caused by various hardware or software fails. When a file gets corrupted, it will no longer function accurately, so an application will not start or will give errors, a text file can be partially or entirely unreadable, an archive file will be impossible to open and 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 serious problem for website hosting servers as problems are more likely to happen on larger in size hard disks where large volumes of information are kept. If a drive is a part of a RAID and the info on it is duplicated on other drives for redundancy, it is very likely that the bad file will be treated as a good one and will be copied on all drives, making the harm permanent. Lots of the file systems that operate on web servers today often cannot identify corrupted files in real time or they need time-consuming system checks through which the server isn't working.

No Data Corruption & Data Integrity in Web Hosting

We've resolved the problem of silent data corruption on all our web hosting servers by using the cutting-edge Z file system, or ZFS. The latter is better than other file systems because it is the only one out there that checks all the files immediately by employing a checksum - a digital identifier which is unique for each file. When you upload content to your account, it'll be stored on several SSD drives and continually synced between them for redundancy. ZFS regularly analyzes the checksum of all files and if any file is detected as damaged, it's replaced right away with a good copy from another disk. As this happens in real time, there's no risk that a damaged file may remain or may be duplicated on the remaining SSDs. ZFS requires a lot of physical memory in order to carry out the real-time checks and the advantage of our cloud hosting platform is that we use multiple powerful servers working together. If you host your websites with us, your information will be intact no matter what.
