Data corruption is the unintentional modification of a file or the loss of info which usually occurs during reading or writing. The reason may be hardware or software fail, and for that reason, a file could become partially or fully corrupted, so it will no longer work correctly as its bits shall be scrambled or lost. An image file, for example, will no longer display a true image, but a random mix of colors, an archive will be impossible to unpack since its content will be unreadable, etcetera. When this kind of an issue appears and it isn't recognized by the system or by an admin, the data will get corrupted silently and if this happens on a disk drive which is a part of a RAID array where the data is synced between different drives, the corrupted file will be duplicated on all of the other drives and the damage will be long term. Many popular file systems either don't feature real-time checks or do not have high quality ones which can detect a problem before the damage is done, so silent data corruption is a common matter on hosting servers where large volumes of data are stored.

No Data Corruption & Data Integrity in Cloud Website Hosting

We've resolved the issue of silent data corruption on all our cloud website hosting servers by using the leading-edge Z file system, or ZFS. The latter is superior to other file systems as it is the only one in existence which checks all of the files right away by employing a checksum - a digital identifier that is unique for each and every file. When you upload content to your account, it'll be stored on several SSD drives and constantly synced between them for redundancy. ZFS constantly analyzes the checksum of all files and if any file is detected as damaged, it is replaced right away with a good copy from some other disk. As this happens in real time, there's no risk that a bad file may remain or may be duplicated on the rest of the SSDs. ZFS needs a lot of physical memory in order to carry out the real-time checks and the advantage of our cloud hosting platform is that we employ multiple very powerful servers working together. In case you host your sites with us, your info will be intact no matter what.

No Data Corruption & Data Integrity in Semi-dedicated Servers

If you acquire one of our semi-dedicated server packages, you won't need to be concerned about silent file corruption because we use ZFS - an advanced file system that keeps track of all the files in real time. Every time you upload a file to your hosting account, ZFS will assign a unique digital fingerprint to it - the so-called checksum. The file will be synced between a number of 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 damaged copy, it replaces it with a healthy one from a different drive. This is done instantly, so there will be no danger for any part of your content at any moment. By comparison, alternative file systems carry out checks only 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 bad copy may be replicated on the other drives as well and you may lose important info. Since this isn't the case with ZFS, we guarantee the integrity of every single file you upload no matter what.
