The process of files being corrupted because of some hardware or software failure is known as data corruption and this is one of the main problems which web hosting companies face since the larger a hard disk drive is and the more data is kept on it, the more likely it is for data to become corrupted. There are a couple of fail-safes, yet often the data becomes corrupted silently, so neither the file system, nor the administrators notice anything. As a result, a damaged file will be handled as a good one and if the hard drive is part of a RAID, the file will be copied on all other disk drives. Theoretically, this is for redundancy, but in reality the damage will get even worse. The moment some file gets corrupted, it will be partly or completely unreadable, therefore 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 shall be impossible to unpack, and you risk losing your site content. Although the most well-known server file systems have various checks, they quite often fail to find a problem early enough or require a long period of time in order to check all of the files and the server will not be operational for the time being.
No Data Corruption & Data Integrity in Shared Website Hosting
The integrity of the data which you upload to your new shared website hosting
account will be ensured by the ZFS file system which we work with on our cloud platform. The majority of web hosting service providers, like our firm, use multiple hard disk drives to store content and since the drives work in a RAID, the same data is synchronized between the drives at all times. When a file on a drive is damaged for whatever reason, however, it is likely that it will be reproduced on the other drives since alternative file systems don't include special checks for this. Unlike them, ZFS employs a digital fingerprint, or a checksum, for every file. If a file gets damaged, its checksum won't match what ZFS has as a record for it, and the bad copy shall be replaced with a good one from a different hard drive. As this happens instantly, there's no possibility for any of your files to ever get corrupted.
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 work with the state-of-the-art ZFS file system. What makes the latter unique is that it uses checksums, or digital identifiers, in order to verify the integrity of every single file. When you upload content to your account, it will be placed on a couple of redundant drives working in a RAID i.e. the files will be the same on all disks. All copies of a particular file will have the same checksum on all drives and ZFS will compare the checksums of the duplicates right away, so if it detects a mismatch, that will indicate that one of the copies is damaged, it will swap that file with a healthy copy from one of the other disks. Even if there is an unforeseen power loss, the data on the servers will not be corrupted and there will not be any need for a time-consuming system check which other file systems perform following some malfunction, lengthening the time needed for the server to get back online. ZFS is the sole file system that can really protect your content from silent data corruption.
