Data corruption is the unintended modification of a file or the loss of info that often occurs during reading or writing. The reason can be hardware or software fail, and as a consequence, a file may become partially or completely corrupted, so it'll no longer function properly because its bits will be scrambled or lost. An image file, for instance, will no longer present an authentic image, but a random mix of colors, an archive will be impossible to unpack because its content will be unreadable, etcetera. If such a problem appears and it's not recognized by the system or by an administrator, the data will become corrupted silently and in case this happens on a disk drive that's a part of a RAID array where the data is synced between various different drives, the corrupted file will be duplicated on all other drives and the damage will be long term. Many widespread file systems either don't have real-time checks or don't have good ones that can detect an issue before the damage is done, so silent data corruption is a very common problem on internet hosting servers where large volumes of data are kept.
No Data Corruption & Data Integrity in Cloud Website Hosting
The integrity of the data which you upload to your new cloud website hosting
account will be guaranteed by the ZFS file system which we employ on our cloud platform. The majority of hosting service providers, like our company, use multiple HDDs to keep content and since the drives work in a RAID, the same data is synchronized between the drives at all times. If a file on a drive becomes damaged for reasons unknown, however, it is very likely that it will be reproduced on the other drives since other file systems do not offer special checks for that. Unlike them, ZFS uses a digital fingerprint, or a checksum, for every single file. If a file gets damaged, its checksum will not match what ZFS has as a record for it, so the bad copy shall be replaced with a good one from another hard disk. 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 Hosting
In case you acquire one of our semi-dedicated hosting
packages, you will not need to worry about silent file corruption because we use ZFS - a high level file system which keeps track of all files in real time. Whenever 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 several SSD drives for redundancy, so if one drive fails, the other ones will take over. ZFS compares the checksum of all copies on the different drives and if it detects a damaged copy, it replaces it with a healthy one from another drive. This is done instantly, so there will be no risk for any part of your content at any time. In comparison, all of the other file systems carry out checks after a system failure, but since they do not use anything similar to the checksums that ZFS uses, they cannot detect silently corrupted files, so a corrupted copy can be replicated on the other disks as well and you can lose crucial data. As this isn't the case with ZFS, we warrant the integrity of each file you upload no matter what.
