The process of files being damaged resulting from some hardware or software failure is called data corruption and this is among the main problems that hosting companies face since the larger a hard disk is and the more info is placed on it, the much more likely it is for data to become corrupted. There are different fail-safes, but often the information gets damaged silently, so neither the file system, nor the admins see anything. Consequently, a corrupted file will be handled as a good one and if the hard disk drive is part of a RAID, that file will be duplicated on all other drives. In principle, this is done for redundancy, but in practice the damage will be worse. The moment a given file gets corrupted, it will be partly or completely unreadable, so a text file will not be readable, an image file will present a random mix of colors in case it opens at all and an archive shall be impossible to unpack, so you risk sacrificing your website content. Although the most commonly used server file systems have various checks, they frequently fail to find a problem early enough or require a vast time period in order to check all of the files and the hosting server will not be operational in the meantime.
No Data Corruption & Data Integrity in Website Hosting
The integrity of the data that you upload to your new website hosting account shall be ensured by the ZFS file system which we take advantage of on our cloud platform. Most of the hosting service providers, like our company, use multiple hard disks to keep content and because the drives work in a RAID, identical info is synchronized between the drives at all times. If a file on a drive is corrupted for reasons unknown, yet, it's very likely that it will be duplicated on the other drives as alternative file systems do not offer special checks for this. Unlike them, ZFS applies a digital fingerprint, or a checksum, for each and every file. In case a file gets corrupted, its checksum won't match what ZFS has as a record for it, and the damaged copy will be replaced with a good one from another drive. Due to the fact that this happens right away, there's no possibility for any of your files to ever be damaged.
No Data Corruption & Data Integrity in Semi-dedicated Hosting
If you obtain one of our semi-dedicated hosting solutions, you will not have to be concerned about silent data corruption since we use ZFS - a high level file system that checks all files in real time. Every time you upload a file to your website hosting account, ZFS will assign a unique digital fingerprint to it - the so-called checksum. This file will be synchronized between several NVMe drives for redundancy, so if a drive fails, the other ones will take control. ZFS compares the checksum of all copies on the different drives and in case it detects a damaged copy, it replaces it with a healthy one from another drive. This is done instantly, so there will be no danger for any part of your content at any moment. In contrast, alternative file systems carry out checks only after a system breakdown, but since they don't use anything similar to the checksums which ZFS uses, they cannot detect silently corrupted files, so a bad copy could be replicated on the remaining drives as well and you could lose important info. Since this isn't the case with ZFS, we're able to warrant the integrity of every single file you upload no matter what.
