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 since the larger a hard disk is and the more information is stored on it, the more likely it is for data to be corrupted. You will find a couple of fail-safes, still often the info becomes corrupted silently, so neither the file system, nor the administrators see anything. Because of this, a corrupted file will be handled as a standard one and if the hard disk drive is part of a RAID, the file will be copied on all other disk drives. In theory, this is done for redundancy, but in practice the damage will get worse. When some file gets damaged, it will be partially or fully unreadable, which means that a text file will not be readable, an image file will present a random mix of colors in case it opens at all and an archive shall be impossible to unpack, and you risk losing your website content. Although the most commonly used server file systems feature various checks, they frequently fail to detect some problem early enough or require a long amount of time to check all the files and the server will not be functional in the meantime.

No Data Corruption & Data Integrity in Shared Hosting

We guarantee the integrity of the info uploaded in each shared hosting account which is created on our cloud platform due to the fact that we use the advanced ZFS file system. The aforementioned is the only one which was designed to avoid silent data corruption via a unique checksum for every single file. We'll store your data on multiple NVMe drives that function in a RAID, so identical files will be available on several places at the same time. ZFS checks the digital fingerprint of all files on all the drives in real time and in case the checksum of any file is different from what it has to be, the file system replaces that file with an undamaged version from a different drive from the RAID. There's no other file system that uses checksums, so it's possible for data to become silently corrupted and the bad file to be replicated on all drives over time, but since this can never happen on a server running ZFS, you don't have to worry about the integrity of your data.

No Data Corruption & Data Integrity in Semi-dedicated Servers

Your semi-dedicated server account will be resistant to silent data corruption because all of our storage servers employ the efficient ZFS file system. What makes the latter unique is that it uses checksums, or digital identifiers, to ensure the integrity of each 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 will be the same on all disks. All copies of a specific file will have the same checksum on all drives and ZFS will compare the checksums of the copies right away, so if it finds a mismatch, which would indicate that one of the copies is damaged, it will swap that file with a good copy from one of the other drives. Even if there is an unexpected blackout, the data on the servers will not get corrupted and there won't be any need for a time-consuming system check that other file systems perform after some failure, extending the time needed for the server to get back online. ZFS is the file system that can truly protect your content from silent data corruption.
