Data corruption is the unintended transformation of a file or the loss of info that often occurs during reading or writing. The reason can be hardware or software failure, and due to this fact, a file could become partially or completely corrupted, so it will no longer function properly since its bits will be scrambled or lost. An image file, for instance, will no longer display 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 this kind of a problem occurs and it's not noticed by the system or by an admin, the data will get corrupted silently and if this happens on a drive that is a part of a RAID array where the data is synchronized between various drives, the corrupted file will be copied on all other drives and the damage will be permanent. Numerous popular file systems either don't offer real-time checks or do not have good ones that can detect a problem before the damage is done, so silent data corruption is a rather common issue on internet hosting servers where large volumes of info are kept.

No Data Corruption & Data Integrity in Hosting

We've resolved the matter of silent data corruption on all of our hosting servers by using the hi-tech Z file system, or ZFS. The latter is superior to other file systems since it is the only one on the market that checks all the files in real time by using a checksum - a digital identifier that is unique for every single file. When you upload content to your account, it'll be stored on several NVMe drives and frequently synced between them for redundancy. ZFS regularly compares the checksum of all files and in the event that any file is detected as damaged, it's 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 copied on the rest of the NVMes. ZFS needs plenty of physical memory to carry out the real-time checks and the benefit of our cloud web hosting platform is that we take advantage of multiple powerful servers working together. In case you host your Internet sites with us, your info will be intact no matter what.

No Data Corruption & Data Integrity in Semi-dedicated Hosting

In case you purchase one of our semi-dedicated hosting solutions, you will not need to worry about silent file corruption since we use ZFS - a high level file system that monitors all 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. That file will be synced between a number of NVMe drives for redundancy, so if a drive fails, the other ones will take control. 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 another drive. This happens immediately, so there will be no threat for any part of your content at any time. By comparison, all the other file systems perform checks only after a system failure, but since they don't use anything similar to the checksums which ZFS uses, they cannot detect silently corrupted files, so a bad copy can be replicated on the other disks as well and you may lose crucial information. Because this is not the case with ZFS, we're able to warrant the integrity of every single file you upload no matter what.
