The process of files getting damaged as a result of some hardware or software failure is referred to as data corruption and this is among the main problems which hosting companies face since the larger a hard disk drive is and the more info is kept on it, the much more likely it is for data to become corrupted. There're different fail-safes, yet often the data is corrupted silently, so neither the particular file system, nor the administrators detect anything. Consequently, a damaged file will be treated as a standard one and if the hard disk drive is part of a RAID, that file will be copied on all other disk drives. Theoretically, this is for redundancy, but in reality the damage will get worse. When some file gets corrupted, it will be partly or fully unreadable, so a text file will no longer be readable, an image file will display a random blend of colors in case it opens at all and an archive will be impossible to unpack, so you risk losing your site content. Although the most widely used server file systems include various checks, they are likely to fail to discover a problem early enough or require a vast time period to check all of the files and the server will not be functional in the meantime.

No Data Corruption & Data Integrity in Hosting

We have tackled the problem of silent data corruption on all our hosting servers by using the cutting-edge Z file system, or ZFS. The latter is superior to other file systems because it is the only one out there that checks all of the files immediately by employing a checksum - a digital identifier that is unique for each file. When you upload content to your account, it'll be stored on several SSD drives and continually synchronized between them for redundancy. ZFS regularly analyzes 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 is no risk that a damaged file may remain or may be copied on the rest of the SSDs. ZFS needs plenty of physical memory to carry out the real-time checks and the benefit of our cloud web hosting platform is that we use multiple very powerful servers working together. If you host your websites with us, your info will be intact no matter what.

No Data Corruption & Data Integrity in Semi-dedicated Servers

You will not need to deal with any kind of silent data corruption issues whatsoever should you obtain one of our semi-dedicated server solutions since the ZFS file system that we take advantage of on our cloud hosting platform uses checksums to ensure that all the files are intact all of the time. A checksum is a unique digital fingerprint that is allotted to each and every file stored on a server. Because we store all content on a number of drives simultaneously, the same file has the same checksum on all of the drives and what ZFS does is that it compares the checksums between the different drives right away. In the event that it detects that a file is corrupted and its checksum is different from what it should be, it replaces that file with a healthy copy right away, avoiding any possibility of the corrupted copy to be synchronized on the remaining drives. ZFS is the sole file system you can get which uses checksums, which makes it much more dependable than other file systems that are not able to detect silent data corruption and duplicate bad files across hard drives.
