Data corruption is the unintentional transformation of a file or the losing of information that often occurs during reading or writing. The reason may be hardware or software failure, and because of this, a file can become partially or completely corrupted, so it will no longer work correctly since its bits shall be scrambled or lost. An image file, for instance, will no longer show a true image, but a random combination of colors, an archive will be impossible to unpack because its content will be unreadable, and so on. In the event that such a problem occurs and it isn't found by the system or by an administrator, the data will get corrupted silently and if this happens on a drive that is part of a RAID array where the info is synced between various different drives, the corrupted file will be copied on all the other drives and the harm will be permanent. Many frequently used file systems either do not offer real-time checks or don't have good ones which will detect an issue before the damage is done, so silent data corruption is a very common issue on web hosting servers where substantial amounts of data are stored.

No Data Corruption & Data Integrity in Shared Hosting

We've resolved the issue of silent data corruption on all of our shared hosting servers by using the leading-edge Z file system, or ZFS. The latter is superior to other file systems since it is the only one out there that checks all of the files instantly 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 continually synced between them for redundancy. ZFS constantly examines the checksum of all files and in case any file is detected as corrupted, it is replaced promptly with a good copy from another disk. As this happens in real time, there is no risk that a bad file may remain or may be duplicated on the other SSDs. ZFS requires lots of physical memory in order to perform the real-time checks and the advantage of our cloud website hosting platform is that we use multiple very powerful servers working together. In case you host your websites with us, your data will be intact no matter what.

No Data Corruption & Data Integrity in Semi-dedicated Hosting

If you acquire one of our semi-dedicated hosting packages, you will not need to worry about silent data corruption since we use ZFS - a high level file system which checks all the files in real time. Every time you upload a file to your web hosting account, ZFS will assign a unique digital fingerprint to it - the so-called checksum. The file will be synchronized between a couple of SSD drives for redundancy, so if a drive fails, the other ones will take over. ZFS compares the checksum of all of the copies on the different drives and if it detects a damaged copy, it replaces it with a healthy one from a different drive. This is done in real time, so there will be no threat for any part of your content at any time. By comparison, all the other file systems execute checks after a system breakdown, but since they do not use anything similar to the checksums that ZFS uses, they can't detect silently corrupted files, so a bad copy can be replicated on the other drives as well and you can lose important information. Since this is not the case with ZFS, we guarantee the integrity of each and every file you upload no matter what.
