Data corruption is the accidental transformation of a file or the losing of info which often occurs during reading or writing. The reason could be hardware or software failure, and due to this fact, a file may become partially or entirely corrupted, so it will no longer work as it should as its bits shall be scrambled or lost. An image file, for instance, will no longer display an actual image, but a random combination of colors, an archive will be impossible to unpack because its content will be unreadable, etcetera. In case this kind of an issue appears and it's not found by the system or by an administrator, the data will become corrupted silently and if this happens on a disk drive that's a part of a RAID array where the data is synchronized between various different drives, the corrupted file will be replicated on all other drives and the damage will become long term. A number of popular file systems either don't feature real-time checks or don't have high quality ones that can detect an issue before the damage is done, so silent data corruption is a very common matter on web hosting servers where substantial amounts of information are stored.
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 employ on our cloud platform. Most internet hosting suppliers, like our company, use multiple HDDs to keep content and considering that the drives work in a RAID, identical information is synchronized between the drives at all times. In case a file on a drive becomes corrupted for some reason, yet, it's likely that it will be copied on the other drives as other file systems do not feature 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 damaged, its checksum will not match what ZFS has as a record for it, which means that the bad copy shall be substituted with a good one from another disk drive. As 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
If you obtain one of our semi-dedicated server
packages, you won't need to be concerned about silent file corruption as we use ZFS - a high level file system that keeps track of all files in real time. Each time you upload a file to your website hosting account, ZFS will assign a unique digital fingerprint to it - the so-called checksum. This file will be synchronized between multiple SSD drives for redundancy, so if one drive fails, the other ones will take over. ZFS compares the checksum of all of the copies on the different drives and when it detects a corrupted copy, it replaces it with a healthy one from a different drive. This happens right away, so there will be no threat for any part of your content at any moment. In contrast, alternative file systems carry out checks after a system malfunction, but since they do not use anything similar to the checksums which ZFS uses, they are unable to detect silently corrupted files, so a corrupted copy may be replicated on the remaining drives as well and you can lose crucial info. Since this isn't the case with ZFS, we're able to guarantee the integrity of every single file you upload no matter what.
