The process of files being damaged caused by some hardware or software failure is called data corruption and this is one of the main problems which web hosting companies face as the larger a hard disk drive is and the more information is stored 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 particular file system, nor the administrators notice anything. Thus, a damaged file will be treated as a standard one and if the hard drive is a part of a RAID, that file will be copied on all other drives. In principle, this is for redundancy, but in reality the damage will be even worse. When some file gets damaged, it will be partially or entirely unreadable, which means that a text file will no longer be readable, an image file will display a random blend of colors if it opens at all and an archive will be impossible to unpack, so you risk losing your site content. Although the most widely used server file systems have various checks, they often fail to discover a problem early enough or require a long time period in order to check all the files and the hosting server will not be operational in the meantime.
No Data Corruption & Data Integrity in Cloud Website Hosting
We warrant the integrity of the data uploaded in any cloud website hosting
account that is generated 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 through a unique checksum for every single file. We shall store your data on multiple SSD drives which operate in a RAID, so identical files will be accessible on several places at once. ZFS checks the digital fingerprint of all of the files on all drives in real time and if the checksum of any file differs from what it has to be, the file system replaces that file with a healthy copy from some other drive inside the RAID. There's no other file system that 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 do not have to concern yourself with the integrity of your data.
No Data Corruption & Data Integrity in Semi-dedicated Hosting
You won't experience any kind of silent data corruption issues if you purchase one of our semi-dedicated hosting
packages as the ZFS file system that we work with on our cloud hosting platform uses checksums to ensure that all the files are undamaged at all times. A checksum is a unique digital fingerprint that is assigned to each and every file stored on a server. Since we store all content on multiple drives simultaneously, the same file has the same checksum on all the drives and what ZFS does is that it compares the checksums between the different drives right away. In case it detects that a file is corrupted and its checksum is different from what it has to be, it replaces that file with a healthy copy right away, avoiding any possibility of the corrupted copy to be synchronized on the other drives. ZFS is the sole file system you will find that uses checksums, which makes it much more dependable than other file systems that are not able to detect silent data corruption and duplicate bad files across drives.
