The process of files being damaged caused by some hardware or software failure is known as data corruption and this is one of the main problems that Internet hosting companies face as the larger a hard drive is and the more info is stored on it, the more likely it is for data to become corrupted. There are several fail-safes, yet often the information is corrupted silently, so neither the file system, nor the administrators notice anything. As a result, a corrupted file will be treated as a standard one and if the hard drive is part of a RAID, the file will be copied on all other drives. In theory, this is done for redundancy, but in practice the damage will be even worse. The moment a file gets damaged, it will be partially or completely unreadable, which means that a text file will not be readable, an image file will show a random combination of colors if it opens at all and an archive will be impossible to unpack, and you risk losing your content. Although the most widespread server file systems feature various checks, they are likely to fail to identify a problem early enough or require a vast period of time to be able to check all of the files and the server will not be operational in the meantime.

No Data Corruption & Data Integrity in Website Hosting

The integrity of the data which you upload to your new website hosting account shall be ensured by the ZFS file system that we use on our cloud platform. Most internet hosting suppliers, including our company, use multiple hard disks to keep content and considering that the drives work in a RAID, the exact same info is synchronized between the drives at all times. If a file on a drive becomes corrupted for reasons unknown, however, it's very likely that it will be copied on the other drives because other file systems don't have special checks for that. In contrast to them, ZFS uses a digital fingerprint, or a checksum, for each and every file. In the event that a file gets damaged, its checksum will not match what ZFS has as a record for it, so the damaged copy shall be substituted with a good one from a different drive. Since this happens instantly, there's no possibility for any of your files to ever get corrupted.

No Data Corruption & Data Integrity in Semi-dedicated Servers

If you go for one of our semi-dedicated server plans, you will not have to worry about silent file corruption as we use ZFS - a high level file system that checks all the files in real time. Every time you upload a file to your account, ZFS will assign a unique digital fingerprint to it - the so-called checksum. The file will be synced between a couple of SSD drives for redundancy, so if one drive fails, the other ones will take control. ZFS compares the checksum of all of the copies on the different drives and in case it detects a corrupted copy, it replaces it with a healthy one from a different drive. This is done in real time, so there will be no threat for any part of your content at any moment. By comparison, alternative file systems carry out checks after a system breakdown, but since they don't use anything similar to the checksums that ZFS uses, they won't detect silently corrupted files, so a bad copy could be replicated on the other drives as well and you may lose critical information. Because this is not the case with ZFS, we're able to guarantee the integrity of every single file you upload no matter what.
