The process of files being damaged resulting from some hardware or software failure is referred to as data corruption and this is among the main problems that Internet hosting companies face since the larger a hard disk drive is and the more data is stored on it, the more likely it is for data to get corrupted. You'll find several fail-safes, yet often the info is corrupted silently, so neither the file system, nor the administrators see a thing. Because of this, a corrupted file will be handled as a standard one and if the HDD is part of a RAID, that file will be copied on all other disk drives. In principle, this is for redundancy, but in reality the damage will get even worse. When some file gets damaged, it will be partly or entirely unreadable, therefore a text file will not be readable, an image file will show a random combination of colors in case it opens at all and an archive shall be impossible to unpack, so you risk losing your content. Although the most widely used server file systems feature various checks, they are likely to fail to discover a problem early enough or require a vast time period to check all the files and the hosting server will not be operational in the meantime.

No Data Corruption & Data Integrity in Cloud Hosting

We have tackled the issue of silent data corruption on all of our cloud hosting servers by using the hi-tech Z file system, or ZFS. The latter is more advanced than other file systems as it is the only one on the market which checks all files right away by using a checksum - a digital identifier which is 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 constantly examines the checksum of all files and when any file is detected as damaged, it is replaced right away with a good copy from some other disk. As this happens in real time, there is no risk that a bad file may remain or may be copied on the remaining NVMes. ZFS requires lots of physical memory in order to carry out the real-time checks and the benefit of our cloud website hosting platform is that we use multiple powerful servers working together. If you host your websites with us, your information will be undamaged no matter what.

No Data Corruption & Data Integrity in Semi-dedicated Hosting

You won't experience any kind of silent data corruption issues should you obtain one of our semi-dedicated hosting plans as the ZFS file system that we use on our cloud hosting platform uses checksums to guarantee that all files are undamaged all of the time. A checksum is a unique digital fingerprint which is allotted to each and every file stored on a server. As we store all content on multiple drives at the same time, 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 in real time. In case 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 probability of the bad copy to be synchronized on the remaining drives. ZFS is the sole file system on the market which uses checksums, which makes it much more dependable than other file systems that cannot identify silent data corruption and duplicate bad files across hard drives.
