The process of files being damaged owing to some hardware or software failure is referred to as data corruption and this is among the main problems that web hosting companies face since the larger a hard disk is and the more info is stored on it, the more likely it is for data to get corrupted. There're various fail-safes, yet often the data becomes damaged silently, so neither the file system, nor the admins detect anything. Thus, a damaged file will be treated as a standard one and if the hard disk drive is part of a RAID, the file will be copied on all other disk drives. Theoretically, this is done for redundancy, but in practice the damage will be even worse. When a given file gets corrupted, it will be partly or completely unreadable, so a text file will not be readable, an image file will present a random combination of colors if it opens at all and an archive shall be impossible to unpack, and you risk losing your site content. Although the most frequently used server file systems include various checks, they quite often fail to detect some problem early enough or require an extensive time period in order to check all the files and the web server will not be operational for the time being.
No Data Corruption & Data Integrity in Cloud Hosting
The integrity of the data which you upload to your new cloud hosting
account will be ensured by the ZFS file system that we take advantage of on our cloud platform. Most of the hosting suppliers, including our company, use multiple HDDs to keep content and since the drives work in a RAID, the same data is synchronized between the drives all of the time. When a file on a drive is damaged for reasons unknown, however, it's likely that it will be duplicated on the other drives as alternative file systems do not include special checks for that. Unlike them, ZFS uses a digital fingerprint, or a checksum, for every file. In case a file gets corrupted, its checksum won't match what ZFS has as a record for it, which means that the damaged copy will be replaced with a good one from a different drive. Due to the fact that this happens instantly, there is no possibility for any of your files to ever get damaged.
No Data Corruption & Data Integrity in Semi-dedicated Servers
You won't experience any kind of silent data corruption issues whatsoever should you purchase one of our semi-dedicated server
solutions because the ZFS file system that we employ on our cloud hosting platform uses checksums in order to guarantee that all files are intact at all times. A checksum is a unique digital fingerprint that is allotted to each and every file saved on a server. Due to the fact that we store all content on multiple drives simultaneously, the same file uses the same checksum on all of the drives and what ZFS does is that it compares the checksums between the different drives in real time. When 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 without delay, avoiding any chance of the corrupted copy to be synchronized on the remaining hard drives. ZFS is the sole file system out there that uses checksums, which makes it much more dependable than other file systems which are unable to detect silent data corruption and copy bad files across hard drives.
