The process of files being damaged as a result of some hardware or software failure is known as data corruption and this is among the main problems which web hosting companies face because the larger a hard drive is and the more information is filed on it, the more likely it is for data to get corrupted. There are different fail-safes, but often the information becomes damaged silently, so neither the particular file system, nor the admins notice a thing. Consequently, a bad file will be handled as a good one and if the hard drive is part of a RAID, that file will be copied on all other disk drives. In theory, this is for redundancy, but in practice the damage will be worse. The moment a file gets damaged, it will be partly or completely unreadable, which means that a text file will not be readable, an image file will display a random blend of colors in case it opens at all and an archive shall be impossible to unpack, and you risk losing your website content. Although the most widespread server file systems have various checks, they often fail to detect some problem early enough or require a long time period to be able to check all the files and the web server will not be operational in the meantime.
No Data Corruption & Data Integrity in Shared Hosting
We warrant the integrity of the information uploaded in any shared hosting
account which is made on our cloud platform because we employ the advanced ZFS file system. The aforementioned is the only one that was designed to prevent silent data corruption through a unique checksum for each and every file. We shall store your info on a large number of SSD drives which function in a RAID, so the same files will be present on several places at once. ZFS checks the digital fingerprint of all the files on all of the drives in real time and in the event that the checksum of any file differs from what it needs to be, the file system replaces that file with a healthy version from a different drive inside 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 reproduced on all drives over time, but since this can never happen on a server using ZFS, you do not have to concern yourself with the integrity of your data.
No Data Corruption & Data Integrity in Semi-dedicated Servers
In case you purchase one of our semi-dedicated server
packages, you won't have to be concerned about silent data corruption since we use ZFS - an advanced file system which keeps track of all the files in real time. Each time you upload a file to your account, ZFS will assign a unique digital fingerprint to it - the so-called checksum. The file will be synchronized between a number of SSD drives for redundancy, so if a drive fails, the other ones will take over. ZFS compares the checksum of all of the copies on the different drives and if it detects a corrupted copy, it replaces it with a healthy one from another drive. This is done in real time, so there will be no danger for any part of your content at any moment. In contrast, other file systems perform checks only after a system breakdown, but since they do not use anything similar to the checksums which ZFS uses, they can't detect silently corrupted files, so a bad copy may be replicated on the other drives as well and you can lose precious information. Because this isn't the case with ZFS, we can warrant the integrity of each and every file you upload no matter what.
