The process of files being corrupted resulting from some hardware or software failure is referred to as data corruption and this is among the main problems that Internet hosting companies face as the larger a hard drive is and the more information is kept on it, the much more likely it is for data to become corrupted. There are several fail-safes, yet often the data gets damaged silently, so neither the particular file system, nor the admins see a thing. As a result, a damaged file will be treated as a standard one and if the hard disk drive is a 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 get worse. When a given file gets corrupted, it will be partially or completely unreadable, so a text file will not be readable, an image file will display a random combination of colors in case it opens at all and an archive shall be impossible to unpack, and you risk sacrificing your website content. Although the most commonly used server file systems include various checks, they are likely to fail to discover a problem early enough or require a vast period of time to be able to check all the files and the web hosting 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 guaranteed by the ZFS file system which we employ on our cloud platform. The vast majority of hosting providers, like our company, use multiple hard disks to keep content and considering that the drives work in a RAID, the exact same information is synchronized between the drives all the time. When a file on a drive is damaged for whatever reason, however, it is more than likely that it will be duplicated on the other drives because alternative file systems don't feature special checks for this. Unlike them, ZFS uses 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, which means that the damaged copy shall be swapped with a good one from a different drive. As this happens in real time, there is no risk for any of your files to ever be corrupted.

No Data Corruption & Data Integrity in Semi-dedicated Servers

If you get one of our semi-dedicated server plans, you will not have to be concerned about silent data corruption because we use ZFS - an advanced file system which monitors all files in real time. Every 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 several SSD drives for redundancy, so if a drive fails, the other ones will take over. ZFS compares the checksum of all copies on the different drives and when 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 time. By comparison, other file systems carry out checks only after a system breakdown, but since they do not use anything similar to the checksums which ZFS uses, they will not detect silently corrupted files, so a corrupted copy may be replicated on the remaining drives as well and you could lose crucial info. As this is not the case with ZFS, we are able to guarantee the integrity of each file you upload no matter what.
