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 drive is and the more information is kept on it, the more likely it is for data to get corrupted. You'll find various fail-safes, yet often the information is corrupted silently, so neither the particular file system, nor the admins detect a thing. Because of this, a damaged file will be handled as a standard one and if the hard disk is part of a RAID, that file will be duplicated on all other disk drives. Theoretically, this is done for redundancy, but in reality the damage will get even worse. The moment a file gets damaged, it will be partly or completely unreadable, so a text file will no longer be readable, an image file will display a random blend of colors in case it opens at all and an archive shall be impossible to unpack, and you risk sacrificing your content. Although the most widespread server file systems feature various checks, they often fail to detect a problem early enough or require a long time period in order to check all files and the hosting server will not be operational in the meantime.

No Data Corruption & Data Integrity in Shared Website Hosting

The integrity of the data which you upload to your new shared website hosting account shall be guaranteed by the ZFS file system that we employ on our cloud platform. The vast majority of web hosting suppliers, like our company, use multiple hard drives to keep content and since the drives work in a RAID, the same information is synchronized between the drives all the time. When a file on a drive is corrupted for some reason, however, it's more than likely that it will be reproduced on the other drives because alternative file systems do not feature special checks for that. Unlike them, ZFS uses a digital fingerprint, or a checksum, for each file. If a file gets corrupted, its checksum won't match what ZFS has as a record for it, and the bad copy shall be swapped with a good one from a different hard disk. Because this happens instantly, there's no risk for any of your files to ever get corrupted.

No Data Corruption & Data Integrity in Semi-dedicated Hosting

Your semi-dedicated hosting account will be resistant to silent data corruption as all our storage servers use the effective ZFS file system. What makes the aforementioned unique is that it uses checksums, or digital identifiers, to ensure the integrity of each file. When you upload content to your account, it will be saved on a couple of redundant drives employed in a RAID i.e. the files will be the same on all disks. All of the copies of a given file will feature the same checksum on all hard drives and ZFS will compare the checksums of the copies quickly, so if it discovers a mismatch, which would indicate that one of the copies is corrupted, it'll substitute that file with a good copy from one of the other drives. Even if there is an unexpected power loss, the data on the servers will not become corrupted and there won't be any need for a time-consuming system check that other file systems perform after some breakdown, lengthening the time needed for the server to return online. ZFS is the sole file system which can really protect your content from silent data corruption.
