Data corruption is the unintended modification of a file or the loss of info which usually occurs during reading or writing. The reason can be hardware or software fail, and for that reason, a file may become partially or entirely corrupted, so it will no longer work properly as its bits shall be scrambled or lost. An image file, for instance, will no longer display a real image, but a random mix of colors, an archive will be impossible to unpack as its content will be unreadable, etc. In the event that such a problem occurs and it's not noticed by the system or by an administrator, the data will be corrupted silently and if this happens on a disk drive that is part of a RAID array where the info is synced between various drives, the corrupted file will be duplicated on all the other drives and the damage will be permanent. Many widely used file systems either don't offer real-time checks or don't have high quality ones that can detect a problem before the damage is done, so silent data corruption is a common problem on internet hosting servers where large amounts of data are kept.
No Data Corruption & Data Integrity in Cloud Website Hosting
We guarantee the integrity of the information uploaded in every cloud website hosting
account which is made on our cloud platform due to the fact that we work with the advanced ZFS file system. The aforementioned is the only one that was designed to avert silent data corruption using a unique checksum for each file. We'll store your info on a number of SSD drives that operate in a RAID, so the very same files will be present on several places at the same time. ZFS checks the digital fingerprint of all of the files on all drives in real time and in the event that the checksum of any file is different from what it has to be, the file system swaps that file with a healthy version from a different drive in the RAID. There's no other file system that uses checksums, so it's possible for data to get silently damaged and the bad file to be replicated on all drives with time, but since that can never happen on a server running ZFS, you will not have to concern yourself with the integrity of your information.
No Data Corruption & Data Integrity in Semi-dedicated Servers
If you buy one of our semi-dedicated server
plans, you will not have to be concerned about silent data corruption since we use ZFS - an advanced file system that keeps track of all of the files in real time. Every time 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 several SSD drives for redundancy, so if a drive fails, the other ones will take control. 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 right away, so there will be no danger for any part of your content at any time. By comparison, other file systems execute checks only after a system malfunction, but since they do not use anything similar to the checksums that ZFS uses, they will not detect silently corrupted files, so a corrupted copy can be replicated on the rest of the disks as well and you could lose precious information. As this isn't the case with ZFS, we warrant the integrity of every single file you upload no matter what.
