The process of files getting damaged caused by some hardware or software failure is referred to as data corruption and this is one of the main problems that Internet hosting companies face because the larger a hard disk is and the more data is placed on it, the more likely it is for data to be corrupted. You can find different fail-safes, still often the data is damaged silently, so neither the particular file system, nor the administrators detect anything. Thus, a damaged file will be treated as a good one and if the hard disk is part of a RAID, the file will be copied on all other disk drives. In principle, this is done for redundancy, but in practice the damage will be even worse. Once some file gets corrupted, it will be partially or entirely unreadable, so a text file will no longer be readable, an image file will present a random mix of colors in case it opens at all and an archive will be impossible to unpack, so you risk losing your content. Although the most widespread server file systems include various checks, they often fail to discover a problem early enough or require a long amount of time in order to check all of the files and the web hosting 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 each and every cloud web hosting
account which is generated on our cloud platform due to the fact that we employ the advanced ZFS file system. The latter is the only one that was designed to prevent silent data corruption via a unique checksum for each file. We shall store your info on a large number of SSD drives that function in a RAID, so the same files will be present on several places at the same time. ZFS checks the digital fingerprint of all the files on all of 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 within the RAID. There's no other file system which uses checksums, so it is possible for data to become 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 will not have to worry about the integrity of your information.
No Data Corruption & Data Integrity in Semi-dedicated Servers
Your semi-dedicated server
account will be shielded from silent data corruption as all our storage servers use the state-of-the-art ZFS file system. What makes the latter unique is that it uses checksums, or digital identifiers, so as to verify the integrity of every single file. When you upload content to your account, it'll be placed on several redundant drives employed in a RAID i.e. the files will be the same on all drives. All of the copies of a specific file will feature the same checksum on all drives and ZFS will compare the checksums of the duplicates right away, so if it identifies a mismatch, which would indicate that one of the copies is corrupted, it will replace that file with a good copy from one of the other disks. Even if there is an unforeseen power failure, the data on the servers won't be corrupted and there won't 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 return online. ZFS is the sole file system which can really protect your content from silent data corruption.
