The process of files getting corrupted as a consequence of some hardware or software failure is known as data corruption and this is among the main problems which hosting companies face as the larger a hard drive is and the more information is placed on it, the more likely it is for data to become corrupted. You will find various fail-safes, still often the data gets corrupted silently, so neither the particular file system, nor the admins notice a thing. Consequently, a corrupted file will be handled as a regular one and if the hard disk drive is part of a RAID, the file will be duplicated on all other drives. Theoretically, this is done for redundancy, but in practice the damage will be even worse. The moment some file gets damaged, it will be partially or completely unreadable, therefore a text file will no longer be readable, an image file will show a random blend of colors in case it opens at all and an archive will be impossible to unpack, and you risk sacrificing your website content. Although the most frequently used server file systems have various checks, they quite often fail to discover some problem early enough or require a long time period to be able to check all the files and the server will not be operational for the time being.
No Data Corruption & Data Integrity in Web Hosting
We warrant the integrity of the data uploaded in every single web hosting account which is made on our cloud platform since we work with the advanced ZFS file system. The latter is the only one that was designed to avoid silent data corruption through a unique checksum for each and every file. We shall store your info on a large number of SSD drives that operate in a RAID, so exactly the same files will exist on several places at the same time. ZFS checks the digital fingerprint of all of the files on all of the drives in real time and if the checksum of any file is different from what it needs to be, the file system swaps that file with a healthy copy from a different drive in the RAID. There's no other file system which uses checksums, so it is possible for data to be silently damaged and the bad file to be duplicated on all drives over time, but since this can never happen on a server using ZFS, you do not have to worry about the integrity of your information.
No Data Corruption & Data Integrity in Semi-dedicated Servers
Your semi-dedicated server account will be shielded from silent data corruption as all our storage servers make use of the reliable ZFS file system. What makes the aforementioned unique is that it employs checksums, or digital identifiers, so as to verify the integrity of each and every file. When you upload content to your account, it will be saved on several redundant drives in a RAID i.e. the files shall be the same across all drives. All the copies of a particular file will feature the same checksum on all drives and ZFS will compare the checksums of the duplicates right away, so if it detects a mismatch, that would indicate that one of the copies is corrupted, it'll replace that file with a healthy copy from one of the other drives. Even if there's a sudden 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 failure, lengthening the time needed for the server to return online. ZFS is the only file system which can really protect your content from silent data corruption.
