The process of files getting corrupted due to some hardware or software failure is referred to as data corruption and this is among the main problems which hosting companies face as the larger a hard disk is and the more information is filed on it, the much more likely it is for data to be corrupted. There are a couple of fail-safes, still often the data becomes corrupted silently, so neither the file system, nor the admins detect a thing. As a result, a bad 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. Theoretically, this is for redundancy, but in reality the damage will be even worse. When a file gets corrupted, it will be partially or fully unreadable, so a text file will no longer be readable, an image file will show a random blend of colors if it opens at all and an archive will be impossible to unpack, so you risk sacrificing your content. Although the most widespread server file systems include various checks, they quite often fail to find some problem early enough or require a long amount of time to be able to check all files and the server will not be functional in the meantime.

No Data Corruption & Data Integrity in Shared Website Hosting

We warrant the integrity of the data uploaded in every single shared website hosting account that is made on our cloud platform because we employ the advanced ZFS file system. The latter is the only one that was designed to avert silent data corruption thanks to a unique checksum for each and every file. We'll store your information on multiple NVMe drives that work in a RAID, so the very same files will be accessible on several places at once. ZFS checks the digital fingerprint of all files on all of the drives in real time and in the event that the checksum of any file differs from what it has to be, the file system swaps that file with a healthy version from a different drive within the RAID. No other file system uses checksums, so it's easy for data to become silently corrupted and the bad file to be replicated on all drives with time, but since that can never happen on a server using ZFS, you will not have to worry about the integrity of your data.
