The process of files getting corrupted due to 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 disk drive is and the more data is kept on it, the much more likely it is for data to get corrupted. You'll find different fail-safes, but often the info gets damaged silently, so neither the file system, nor the admins see anything. Because of this, 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 duplicated on all other drives. In theory, this is done for redundancy, but in practice the damage will get even 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 show a random mix of colors if it opens at all and an archive shall be impossible to unpack, so you risk sacrificing your site content. Although the most popular server file systems feature various checks, they often fail to discover some problem early enough or require an extensive period of time to be able to check all files and the web server will not be functional in the meantime.

No Data Corruption & Data Integrity in Shared Hosting

The integrity of the data that you upload to your new shared hosting account will be ensured by the ZFS file system which we make use of on our cloud platform. The majority of internet hosting suppliers, like our company, use multiple hard drives to store 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 gets damaged for whatever reason, however, it's more than likely that it will be reproduced on the other drives because alternative file systems do not offer special checks for that. In contrast to them, ZFS applies a digital fingerprint, or a checksum, for each and every file. In case a file gets corrupted, its checksum won't match what ZFS has as a record for it, so the damaged copy will be replaced with a good one from another drive. Since this happens immediately, there's no possibility for any of your files to ever be damaged.

No Data Corruption & Data Integrity in Semi-dedicated Servers

Your semi-dedicated server account will be resistant to silent data corruption because all of our storage servers make use of the innovative ZFS file system. What makes the aforementioned unique is that it employs checksums, or digital identifiers, to verify the integrity of every single file. When you upload content to your account, it will be saved on a couple of redundant drives operating in a RAID i.e. the files shall be the same on all disk drives. All the copies of a given file will have the same checksum on all hard disks and ZFS will compare the checksums of the duplicates right away, so if it finds a mismatch, which will indicate that one of the copies is corrupted, it'll substitute that file with a healthy copy from one of the other drives. Even if there is an unexpected power loss, the data on the servers will not be corrupted and there won't be any need for a time-consuming system check which other file systems perform after some malfunction, lengthening the time needed for the server to return online. ZFS is the sole file system which can truly protect your content from silent data corruption.
