Data corruption is the unintentional change of a file or the losing of information that usually occurs during reading or writing. The reason can be hardware or software failure, and because of this, a file may become partially or fully corrupted, so it'll no longer function as it should as its bits shall be scrambled or lacking. An image file, for example, will no longer present an authentic image, but a random mix of colors, an archive will be impossible to unpack as its content will be unreadable, etcetera. In the event that such an issue appears and it is not noticed by the system or by an admin, the data will get corrupted silently and when this happens on a disk drive which is a part of a RAID array where the data is synchronized between various different drives, the corrupted file will be duplicated on all of the other drives and the harm will be long term. A number of popular file systems either don't have 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 common issue on web hosting servers where substantial volumes of info are stored.
No Data Corruption & Data Integrity in Cloud Website Hosting
In case you host your sites in a cloud website hosting account from our firm, you will not need to worry about any of your data ever getting damaged. We can guarantee that as our cloud hosting platform works with the advanced ZFS file system. The latter is the only file system which uses checksums, or unique digital fingerprints, for each and every file. All of the info that you upload will be kept in a RAID i.e. simultaneously on a large number of SSDs. A lot of file systems synchronize the files between the separate drives using such a setup, but there's no real warranty that a file won't get corrupted. This can occur throughout the writing process on each drive and then a bad copy can be copied on all other drives. What is different on our platform is that ZFS compares the checksums of all files on all drives instantly and in the event that a corrupted file is identified, it is replaced with a good copy with the correct checksum from some other drive. That way, your info will continue to be unharmed no matter what, even if an entire drive fails.
No Data Corruption & Data Integrity in Semi-dedicated Hosting
In case you get one of our semi-dedicated hosting packages, you won't have to be concerned about silent data corruption because we use ZFS - a high level file system which monitors all the files in real time. Whenever you upload a file to your hosting account, ZFS will assign a unique digital fingerprint to it - the so-called checksum. This file will be synced between a couple of SSD drives for redundancy, so if one drive fails, the other ones will take control. ZFS compares the checksum of all copies on the different drives and in case it detects a damaged copy, it replaces it with a healthy one from another drive. This is done in real time, so there will be no danger for any part of your content at any moment. In comparison, alternative file systems carry out checks only after a system failure, but since they do not use anything similar to the checksums that ZFS uses, they won't detect silently corrupted files, so a bad copy could be replicated on the rest of the drives as well and you could lose critical information. Since this is not the case with ZFS, we can warrant the integrity of every single file you upload no matter what.
