The process of files being 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 info is stored on it, the more likely it is for data to get corrupted. There're several fail-safes, but often the information is corrupted silently, so neither the particular file system, nor the administrators see anything. Consequently, a damaged file will be handled as a regular one and if the hard disk drive is a part of a RAID, the file will be copied on all other disk drives. In principle, this is done for redundancy, but in practice the damage will be worse. Once a given file gets damaged, it will be partially or completely unreadable, therefore a text file will not be readable, an image file will display a random mix of colors if it opens at all and an archive shall be impossible to unpack, and you risk sacrificing your content. Although the most commonly used server file systems have various checks, they frequently fail to find some problem early enough or require a vast time period in order to check all the files and the web hosting server will not be functional in the meantime.
No Data Corruption & Data Integrity in Shared Web Hosting
The integrity of the data that you upload to your new shared web hosting
account will be ensured by the ZFS file system that we use on our cloud platform. Most of the hosting service providers, like our company, use multiple HDDs to keep content and considering that the drives work in a RAID, the same data is synchronized between the drives all the time. In case a file on a drive becomes corrupted for reasons unknown, yet, it is more than likely that it will be reproduced on the other drives since alternative file systems don't include special checks for this. In contrast to them, ZFS works with a digital fingerprint, or a checksum, for each file. In case a file gets corrupted, its checksum won't match what ZFS has as a record for it, therefore the damaged copy will be replaced with a good one from a different disk drive. Due to the fact that this happens right away, there is no risk for any of your files to ever be corrupted.
No Data Corruption & Data Integrity in Semi-dedicated Servers
You won't need to deal with any kind of silent data corruption issues if you buy one of our semi-dedicated server
packages because the ZFS file system that we use on our cloud hosting platform uses checksums to guarantee that all the files are intact at all times. A checksum is a unique digital fingerprint which is allotted to each and every file stored on a server. Since we store all content on a number of drives simultaneously, the same file has the same checksum on all drives and what ZFS does is that it compares the checksums between the different drives right away. In case it detects that a file is corrupted and its checksum is different from what it should be, it replaces that file with a healthy copy right away, avoiding any probability of the corrupted copy to be synchronized on the rest of the hard disks. ZFS is the sole file system you can find that uses checksums, which makes it far superior to other file systems that are unable to detect silent data corruption and duplicate bad files across hard drives.
