Data corruption is the unintentional modification of a file or the loss of information that often occurs during reading or writing. The reason may be hardware or software failure, and due to this fact, a file can become partially or fully corrupted, so it'll no longer function correctly as its bits shall be scrambled or lacking. An image file, for example, will no longer display an accurate image, but a random combination of colors, an archive will be impossible to unpack because its content will be unreadable, and so on. In case this kind of a problem appears and it isn't found by the system or by an administrator, the data will get corrupted silently and when this happens on a drive which is part of a RAID array where the info is synchronized between various different drives, the corrupted file shall be reproduced on all the other drives and the damage will be permanent. A number of popular file systems either don't offer real-time checks or do not have good ones that will detect a problem before the damage is done, so silent data corruption is a very common matter on hosting servers where large volumes of data are stored.
No Data Corruption & Data Integrity in Shared Hosting
The integrity of the data which you upload to your new shared hosting account shall be ensured by the ZFS file system that we employ on our cloud platform. The vast majority of web hosting service providers, including our company, use multiple hard disk drives to keep content and since the drives work in a RAID, identical information is synchronized between the drives all the time. In case a file on a drive gets damaged for whatever reason, yet, it's very likely that it will be copied on the other drives as other file systems don't have special checks for that. Unlike them, ZFS employs a digital fingerprint, or a checksum, for each and every file. In case a file gets corrupted, its checksum won't match what ZFS has as a record for it, therefore the bad copy will be swapped with a good one from another hard disk. As this happens right away, there is no risk for any of your files to ever get damaged.
No Data Corruption & Data Integrity in Semi-dedicated Servers
In case you get one of our semi-dedicated server plans, you won't have to be concerned about silent data corruption since we use ZFS - an advanced file system that monitors all the 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. The file will be synchronized between a number of SSD drives for redundancy, so if one drive fails, the other ones will take control. ZFS compares the checksum of all of the copies on the different drives and in case 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 time. In comparison, other file systems execute checks only after a system breakdown, but since they don't use anything similar to the checksums that ZFS uses, they will not detect silently corrupted files, so a bad copy may be replicated on the other disks as well and you may lose critical info. Since this is not the case with ZFS, we warrant the integrity of each file you upload no matter what.
