The process of files getting damaged caused by some hardware or software failure is referred to as data corruption and this is one of the main problems which Internet hosting companies face because the larger a hard disk drive is and the more data is placed on it, the more likely it is for data to be corrupted. You can find various fail-safes, yet often the info gets damaged silently, so neither the file system, nor the administrators notice a thing. Consequently, a damaged file will be handled as a good one and if the HDD is a part of a RAID, that particular file will be copied on all other disk drives. Theoretically, this is for redundancy, but in practice the damage will get even worse. The moment some file gets corrupted, it will be partly or entirely unreadable, which means that a text file will not be readable, an image file will display a random mix of colors in case it opens at all and an archive will be impossible to unpack, so you risk sacrificing your content. Although the most frequently used server file systems have various checks, they often fail to detect some problem early enough or require an extensive amount of time to be able to check all files and the web hosting server will not be operational for the time being.
No Data Corruption & Data Integrity in Shared Hosting
The integrity of the data which you upload to your new shared hosting
account will be guaranteed by the ZFS file system which we take advantage of on our cloud platform. The vast majority of hosting providers, including our company, use multiple hard drives to keep content and because the drives work in a RAID, the same info is synchronized between the drives at all times. In case a file on a drive is corrupted for some reason, yet, it's very likely that it will be reproduced on the other drives since alternative file systems do not include special checks for this. Unlike them, ZFS applies a digital fingerprint, or a checksum, for every file. In the event that a file gets damaged, its checksum will not match what ZFS has as a record for it, therefore the bad copy shall be replaced with a good one from another hard disk drive. Because this happens in real time, there is no possibility for any of your files to ever get damaged.
No Data Corruption & Data Integrity in Semi-dedicated Hosting
In case you go for one of our semi-dedicated hosting
solutions, you won't have to worry about silent data corruption because we use ZFS - a high level file system which keeps track of all of the files in real time. Each time you upload a file to your web hosting account, ZFS will assign a unique digital fingerprint to it - the so-called checksum. The file will be synchronized between multiple SSD drives for redundancy, so if a drive fails, the other ones will take control. ZFS compares the checksum of all of the copies on the different drives and if it detects a damaged copy, it replaces it with a healthy one from another drive. This happens instantly, so there will be no danger for any part of your content at any time. In contrast, other file systems carry out checks after a system failure, but since they don't use anything similar to the checksums which ZFS uses, they will not detect silently corrupted files, so a bad copy can be replicated on the remaining drives as well and you may lose critical data. As this is not the case with ZFS, we can guarantee the integrity of every single file you upload no matter what.
