Data corruption is the accidental transformation of a file or the losing of info which often occurs during reading or writing. The reason can be hardware or software fail, and because of this, a file can become partially or completely corrupted, so it'll no longer function correctly as its bits shall be scrambled or missing. An image file, for example, will no longer show an authentic image, but a random mix of colors, an archive will be impossible to unpack as its content will be unreadable, etc. If this kind of a problem appears and it's not identified by the system or by an administrator, the data will become corrupted silently and if this happens on a disk drive that is a part of a RAID array where the information is synchronized between different drives, the corrupted file will be replicated on all other drives and the damage will become permanent. A large number of widespread file systems either don't have real-time checks or do not have high quality ones that can detect an issue before the damage is done, so silent data corruption is a very common issue on hosting servers where large amounts of info are stored.

No Data Corruption & Data Integrity in Hosting

We have resolved the problem of silent data corruption on all our hosting servers by using the amazing Z file system, or ZFS. The latter is better than other file systems since it is the only one on the market which checks all of the files in real time by using a checksum - a digital identifier which is unique for each and every file. When you upload content to your account, it will be stored on several NVMe drives and continually synced between them for redundancy. ZFS regularly compares the checksum of all files and when any file is detected as corrupted, it's replaced promptly with a good copy from another disk. As this happens in real time, there's no risk that a corrupted file may remain or may be duplicated on the rest of the NVMes. ZFS needs lots 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. If you host your websites with us, your information will be undamaged no matter what.

No Data Corruption & Data Integrity in Semi-dedicated Hosting

Your semi-dedicated hosting account will be shielded from silent data corruption since all our storage servers employ the reliable ZFS file system. What makes the aforementioned unique is that it uses checksums, or digital identifiers, in order to verify the integrity of each file. When you upload content to your account, it'll be placed on several redundant drives in a RAID i.e. the files will be the same on all disk drives. All the copies of a specific file will have the same checksum on all hard disks and ZFS will compare the checksums of the duplicates quickly, and if it detects a mismatch, that would indicate that one of the copies is damaged, it will substitute that file with a good copy from one of the other drives. Even if there's a sudden power failure, the data on the servers will not be corrupted and there will not be any need for a time-consuming system check which other file systems perform after some failure, extending the time needed for the server to get back online. ZFS is the only file system that can really protect your content from silent data corruption.
