The process of files being damaged as a result of some hardware or software failure is referred to as data corruption and this is among the main problems which hosting companies face because the larger a hard disk drive is and the more info is filed on it, the more likely it is for data to become corrupted. You can find several fail-safes, but often the info gets damaged silently, so neither the particular file system, nor the administrators notice anything. Thus, a damaged file will be handled as a regular one and if the hard disk drive is a part of a RAID, that file will be copied on all other disk drives. In theory, this is for redundancy, but in reality the damage will get worse. Once a given file gets corrupted, it will be partially or completely unreadable, which means that a text file will no longer be readable, an image file will present a random blend of colors in case it opens at all and an archive will be impossible to unpack, so you risk sacrificing your website content. Although the most commonly used server file systems feature various checks, they quite often fail to discover a problem early enough or require an extensive time period to check all files and the web server will not be functional for the time being.
No Data Corruption & Data Integrity in Website Hosting
We guarantee the integrity of the info uploaded in each and every website hosting account which is created on our cloud platform as we work with the advanced ZFS file system. The aforementioned is the only one which was designed to prevent silent data corruption thanks to a unique checksum for every single file. We shall store your data on a number of SSD drives which function in a RAID, so exactly the same files will be present on several places concurrently. ZFS checks the digital fingerprint of all the files on all drives in real time and in the event that the checksum of any file is different from what it has to be, the file system swaps that file with a healthy version from another drive inside the RAID. No other file system uses checksums, so it's possible for data to get silently damaged and the bad file to be replicated on all drives over time, but since this can never happen on a server using ZFS, you don't have to concern yourself with the integrity of your data.
No Data Corruption & Data Integrity in Semi-dedicated Hosting
Your semi-dedicated hosting account will be resistant to silent data corruption because all our storage servers make use of the innovative ZFS file system. What makes the aforementioned unique is that it employs checksums, or digital identifiers, to ensure the integrity of each file. When you upload content to your account, it'll be placed on several redundant drives working in a RAID i.e. the files will be the same on all disk drives. All the copies of a particular file will have the same checksum on all drives and ZFS will compare the checksums of the copies right away, so if it detects a mismatch, which will indicate that one of the copies is damaged, it will swap that file with a healthy copy from one of the other drives. Even if there is an unexpected power loss, the data on the servers won't get corrupted and there won't be any need for a time-consuming system check that other file systems perform following some malfunction, extending the time needed for the server to return online. ZFS is the sole file system that can really protect your content from silent data corruption.
