The process of files being damaged as a result of some hardware or software failure is referred to as data corruption and this is one of the main problems which hosting companies face since the larger a hard disk drive is and the more info is stored on it, the much more likely it is for data to be corrupted. You will find a couple of fail-safes, but often the info becomes corrupted silently, so neither the particular file system, nor the admins detect a thing. As a result, a corrupted file will be treated as a good one and if the hard drive is part of a RAID, that particular file will be duplicated on all other disk drives. In theory, this is for redundancy, but in practice the damage will be worse. The moment some file gets corrupted, it will be partially or entirely unreadable, so a text file will not be readable, an image file will present a random combination of colors if it opens at all and an archive will be impossible to unpack, so you risk sacrificing your content. Although the most well-known server file systems have various checks, they quite often fail to find some problem early enough or require an extensive period of time to be able to check all files and the hosting server will not be operational for the time being.
No Data Corruption & Data Integrity in Cloud Website Hosting
We guarantee the integrity of the info uploaded in any cloud website hosting
account that is generated on our cloud platform due to the fact that we employ the advanced ZFS file system. The aforementioned is the only one which was designed to avoid silent data corruption through a unique checksum for each and every file. We will store your information on a number of SSD drives which operate in a RAID, so the same files will be available on several places concurrently. ZFS checks the digital fingerprint of all of the files on all drives in real time and in case the checksum of any file differs from what it has to be, the file system replaces that file with a healthy copy from another drive from the RAID. There's no other file system that uses checksums, so it is possible for data to get silently corrupted and the bad file to be reproduced on all drives over time, but since that can never happen on a server using 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 protected against silent data corruption as all of our storage servers work with the reliable ZFS file system. What makes the aforementioned unique is that it employs checksums, or digital identifiers, to ensure the integrity of every single file. When you upload content to your account, it'll be placed on several redundant drives working in a RAID i.e. the files shall be the same on all disks. All the copies of a particular file will feature the same checksum on all hard disks and ZFS will compare the checksums of the duplicates in real time, and if it identifies a mismatch, that would indicate that one of the copies is corrupted, it'll replace that file with a healthy copy from one of the other disks. Even if there is an unexpected blackout, the data on the servers will not get 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 sole file system which can really protect your content from silent data corruption.
