Data corruption is the damage of information due to various software or hardware failures. After a file gets damaged, it will no longer work properly, so an application will not start or shall give errors, a text file can be partially or fully unreadable, an archive file will be impossible to open then unpack, etc. Silent data corruption is the process of information getting damaged without any acknowledgement by the system or an administrator, which makes it a serious problem for website hosting servers as failures are much more likely to occur on larger hard drives where vast volumes of info are kept. In case a drive is part of a RAID and the information on it is copied on other drives for redundancy, it is more than likely that the bad file will be treated as a regular one and it'll be copied on all drives, making the damage permanent. Lots of the file systems that run on web servers these days often are not able to find corrupted files immediately or they need time-consuming system checks during which the server is not functioning.

No Data Corruption & Data Integrity in Cloud Web Hosting

We've resolved the problem of silent data corruption on all of our cloud web hosting servers by using the amazing Z file system, or ZFS. The latter is more advanced than other file systems as it is the only one out there that checks all files in real time by employing a checksum - a digital identifier which is unique for each and every file. When you upload content to your account, it'll be stored on several NVMe drives and constantly synced between them for redundancy. ZFS regularly compares the checksum of all files and if any file is detected as damaged, it's replaced instantly 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 duplicated on the remaining NVMes. ZFS needs a lot of physical memory in order to perform the real-time checks and the advantage of our cloud hosting platform is that we use multiple powerful servers working together. In case you host your sites with us, your info will be undamaged no matter what.

No Data Corruption & Data Integrity in Semi-dedicated Hosting

You won't experience any silent data corruption issues whatsoever in case you get one of our semi-dedicated hosting packages since the ZFS file system that we employ on our cloud hosting platform uses checksums to guarantee that all of the files are intact all 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 a number of drives at the same time, 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 right away. 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 without delay, avoiding any possibility of the damaged copy to be synchronized on the rest of the hard disks. ZFS is the only file system out there which uses checksums, which makes it far superior to other file systems that are unable to identify silent data corruption and duplicate bad files across hard drives.
