The process of files being corrupted due to some hardware or software failure is known as data corruption and this is among the main problems that web hosting companies face since the larger a hard disk drive is and the more data is filed on it, the much more likely it is for data to be corrupted. You can find a couple of fail-safes, yet often the information is damaged silently, so neither the file system, nor the admins detect anything. Because of this, a corrupted file will be treated as a good one and if the hard disk is a part of a RAID, that particular file will be copied on all other disk drives. In principle, this is for redundancy, but in reality the damage will be worse. The moment some file gets corrupted, it will be partially or completely unreadable, so a text file will no longer be readable, an image file will display a random blend of colors if it opens at all and an archive will be impossible to unpack, and you risk losing your site content. Although the most commonly used server file systems have various checks, they quite often fail to identify some problem early enough or require a vast period of time to check all files and the hosting server will not be functional in the meantime.
No Data Corruption & Data Integrity in Cloud Hosting
The integrity of the data that you upload to your new cloud hosting
account will be guaranteed by the ZFS file system that we work with on our cloud platform. The majority of hosting service providers, including our firm, use multiple hard disk drives to keep content and because the drives work in a RAID, the exact same data is synchronized between the drives all of the time. When a file on a drive gets corrupted for whatever reason, however, it's more than likely that it will be reproduced on the other drives because other file systems don't offer special checks for this. In contrast to them, ZFS works with a digital fingerprint, or a checksum, for each file. In the event that a file gets corrupted, its checksum will not match what ZFS has as a record for it, and the damaged copy shall be substituted with a good one from a different hard disk drive. Since this happens immediately, there's no risk for any of your files to ever get corrupted.
No Data Corruption & Data Integrity in Semi-dedicated Servers
In case you buy one of our semi-dedicated server
solutions, you will not need to worry about silent data corruption since we use ZFS - a high level file system that checks all of the 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. That file will be synced between multiple SSD drives for redundancy, so if one drive fails, the other ones will take over. ZFS compares the checksum of all copies on the different drives and if it detects a damaged copy, it replaces it with a healthy one from another drive. This happens in real time, so there will be no risk for any part of your content at any moment. In contrast, all the other file systems execute checks after a system failure, but since they do not use anything similar to the checksums which ZFS uses, they will not detect silently corrupted files, so a bad copy could be replicated on the other drives as well and you may lose precious data. Since this isn't the case with ZFS, we are able to guarantee the integrity of each file you upload no matter what.
