The process of files being corrupted owing to some hardware or software failure is called data corruption and this is among the main problems that Internet hosting companies face since the larger a hard disk drive is and the more info is stored on it, the much more likely it is for data to get corrupted. You can find different fail-safes, yet often the data becomes damaged silently, so neither the particular file system, nor the admins detect anything. Thus, a bad file will be treated as a good one and if the hard drive is a part of a RAID, that file will be copied on all other drives. In theory, this is for redundancy, but in reality the damage will be even worse. When a file gets corrupted, it will be partly or fully unreadable, so a text file will no longer be readable, an image file will display a random blend of colors if it opens at all and an archive shall be impossible to unpack, so you risk sacrificing your content. Although the most widespread server file systems have various checks, they quite often fail to find a problem early enough or require a long period of time in order to check all files and the hosting server will not be operational 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 shall be ensured by the ZFS file system that we use on our cloud platform. The vast majority of internet hosting suppliers, like our company, use multiple HDDs to keep content and because the drives work in a RAID, the exact same info is synchronized between the drives all of the time. In case a file on a drive gets corrupted for whatever reason, yet, it is more than likely that it will be reproduced on the other drives since other file systems don't have special checks for that. In contrast to them, ZFS applies a digital fingerprint, or a checksum, for every single file. In case a file gets corrupted, its checksum will not match what ZFS has as a record for it, so the damaged copy shall be substituted with a good one from another hard drive. Because this happens right away, there is no possibility for any of your files to ever be corrupted.
No Data Corruption & Data Integrity in Semi-dedicated Servers
You won't experience any kind of silent data corruption issues in case you buy one of our semi-dedicated server
plans due to the fact that the ZFS file system that we take advantage of on our cloud hosting platform uses checksums in order to ensure that all the files are undamaged all the time. A checksum is a unique digital fingerprint which is assigned to each and every file saved on a server. Because we store all content on a number of drives at the same time, the same file has the same checksum on all 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 right away, avoiding any possibility of the damaged copy to be synchronized on the rest of the hard drives. ZFS is the sole file system you can find which uses checksums, which makes it much more reliable than other file systems which cannot detect silent data corruption and duplicate bad files across hard drives.
