Data corruption is the damage of information caused by various hardware or software fails. The moment a file is corrupted, it will no longer function correctly, so an application will not start or will give errors, a text file could be partially or entirely unreadable, an archive will be impossible to open and then unpack, etc. Silent data corruption is the process of information getting damaged without any identification by the system or an admin, that makes it a significant problem for hosting servers as problems are very likely to happen on larger hard disk drives where significant volumes of info are placed. In case a drive is part of a RAID and the data on it is replicated 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 lot of the file systems that operate on web servers today often cannot locate corrupted files immediately or they need time-consuming system checks during which the server isn't functioning.

No Data Corruption & Data Integrity in Cloud Web Hosting

We've tackled the matter of silent data corruption on our cloud web hosting servers by using the state-of-the-art Z file system, or ZFS. The latter is more advanced than other file systems because it is the only one out there which checks all of the files immediately by using a checksum - a digital identifier that is unique for every single file. When you upload content to your account, it will be stored on several SSD drives and frequently synchronized between them for redundancy. ZFS constantly examines the checksum of all files and if any file is detected as corrupted, it's replaced promptly 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 other SSDs. ZFS requires lots of physical memory to carry out 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 Internet sites with us, your information will be intact no matter what.

No Data Corruption & Data Integrity in Semi-dedicated Servers

You will not have to deal with any silent data corruption issues whatsoever in case you acquire one of our semi-dedicated server solutions because the ZFS file system that we use on our cloud hosting platform uses checksums in order to ensure that all the files are intact all of the time. A checksum is a unique digital fingerprint which is allotted to each and every file stored on a server. Since we store all content on a number of drives simultaneously, the same file has 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 possibility of the damaged copy to be synchronized on the rest of the hard drives. ZFS is the only file system available on the market which uses checksums, which makes it far superior to other file systems that are not able to identify silent data corruption and copy bad files across drives.
