The process of files getting corrupted due to some hardware or software failure is called data corruption and this is one of the main problems which hosting companies face because the larger a hard disk is and the more data is stored on it, the much more likely it is for data to get corrupted. There are several fail-safes, still often the information gets damaged silently, so neither the particular file system, nor the administrators notice a thing. Thus, a corrupted file will be treated as a good one and if the hard disk is a part of a RAID, the file will be copied on all other drives. In principle, this is for redundancy, but in reality the damage will get worse. When a given file gets corrupted, it will be partially or entirely unreadable, which means that a text file will no longer be readable, an image file will show a random combination of colors in case it opens at all and an archive will be impossible to unpack, so you risk losing your site content. Although the most widespread server file systems have various checks, they often fail to detect some problem early enough or require a long period of time to be able to check all the files and the web server will not be operational in the meantime.

No Data Corruption & Data Integrity in Cloud Web Hosting

We guarantee the integrity of the information uploaded in any cloud web hosting account which is created on our cloud platform as we employ the advanced ZFS file system. The aforementioned is the only one that was designed to avoid silent data corruption thanks to a unique checksum for each file. We will store your info on a large number of NVMe drives which function in a RAID, so the very same files will be present on several places concurrently. ZFS checks the digital fingerprint of all of the files on all the drives in real time and in case the checksum of any file differs from what it needs to be, the file system swaps that file with a healthy version from a different drive from the RAID. There's no other file system which uses checksums, so it's possible for data to get silently corrupted and the bad file to be replicated on all drives over time, but since that can never happen on a server running ZFS, you do not have to concern yourself with the integrity of your info.

No Data Corruption & Data Integrity in Semi-dedicated Servers

Your semi-dedicated server account will be shielded from silent data corruption since all of our storage servers employ the advanced ZFS file system. What makes the latter unique is that it employs checksums, or digital identifiers, so as to ensure the integrity of each and every file. When you upload content to your account, it'll be stored on a couple of redundant drives operating in a RAID i.e. the files shall be the same on all drives. All of the copies of a particular file will feature the same checksum on all hard drives and ZFS will compare the checksums of the duplicates in real time, so if it detects a mismatch, which would indicate that one of the copies is corrupted, it will substitute that file with a good copy from one of the other disks. Even if there's a sudden blackout, the data on the servers won't be corrupted and there will not be any need for a time-consuming system check that other file systems perform following some malfunction, prolonging the time needed for the server to get back online. ZFS is the file system which can truly protect your content from silent data corruption.
