The process of files getting damaged resulting from some hardware or software failure is called data corruption and this is one of the main problems that Internet hosting companies face as the larger a hard disk is and the more info is filed on it, the more likely it is for data to be corrupted. You can find different fail-safes, yet often the information becomes corrupted silently, so neither the file system, nor the admins notice a thing. Consequently, a corrupted file will be treated as a good one and if the hard disk drive is a part of a RAID, the file will be copied on all other drives. Theoretically, this is done for redundancy, but in practice the damage will get even worse. When a file gets damaged, it will be partly or fully unreadable, therefore a text file will not be readable, an image file will present a random mix of colors if it opens at all and an archive shall be impossible to unpack, so you risk losing your website content. Although the most frequently used server file systems include various checks, they frequently fail to find some problem early enough or require an extensive period of time in order to check all files and the server will not be functional for the time being.

No Data Corruption & Data Integrity in Website Hosting

We have dealt with the problem of silent data corruption on our website 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 that checks all of the files immediately by using 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 NVMe drives and constantly synced between them for redundancy. ZFS regularly analyzes the checksum of all files and when any file is detected as corrupted, it is replaced right away with a good copy from another disk. As this happens in real time, there's no risk that a bad file may remain or may be duplicated on the remaining NVMes. ZFS needs lots of physical memory to execute the real-time checks and the advantage of our cloud web hosting platform is that we take advantage of 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

Your semi-dedicated hosting account will be resistant to silent data corruption since all of our storage servers use the efficient ZFS file system. What makes the latter unique is that it employs checksums, or digital identifiers, to ensure the integrity of each file. When you upload content to your account, it will be saved on a couple of redundant drives working in a RAID i.e. the files shall be the same across all drives. All the copies of a given file will have the same checksum on all drives and ZFS will compare the checksums of the duplicates quickly, so if it finds a mismatch, which will indicate that one of the copies is damaged, it will replace that file with a healthy copy from one of the other disks. Even if there is a sudden power loss, the data on the servers won't get corrupted and there will not be any need for a time-consuming system check which other file systems perform following some malfunction, prolonging the time needed for the server to return online. ZFS is the file system that can really protect your content from silent data corruption.
