Data corruption is the damage of info caused by various hardware or software problems. Once a file gets corrupted, it will no longer function correctly, so an application will not start or will give errors, a text file shall be partially or completely unreadable, an archive file will be impossible to open and then unpack, etc. Silent data corruption is the process of information getting harmed without any identification by the system or an admin, that makes it a serious problem for website hosting servers as fails are more likely to happen on larger in size hard disk drives where significant volumes of information are stored. When a drive is a part of a RAID and the data on it is duplicated on other drives for redundancy, it's very likely that the damaged file will be treated as an undamaged one and it will be copied on all of the drives, making the harm permanent. A huge number of the file systems that run on web servers nowadays often cannot locate corrupted files immediately or they need time-consuming system checks during which the server is not operational.

No Data Corruption & Data Integrity in Cloud Website Hosting

We warrant the integrity of the info uploaded in each and every cloud website hosting account which is generated on our cloud platform because we work with the advanced ZFS file system. The latter is the only one which was designed to avert silent data corruption via a unique checksum for every single file. We will store your data on a large number of SSD drives that work in a RAID, so the very same files will be accessible on several places simultaneously. ZFS checks the digital fingerprint of all of the files on all of the 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 an undamaged copy from another drive from the RAID. No other file system uses checksums, so it's easy for data to get silently damaged and the bad file to be duplicated on all drives with time, but since this can never happen on a server running ZFS, you do not have to concern yourself with the integrity of your information.

No Data Corruption & Data Integrity in Semi-dedicated Hosting

In case you buy one of our semi-dedicated hosting plans, you won't have to worry about silent file corruption because we use ZFS - a high level file system which checks all of the files in real time. Every time you upload a file to your website hosting account, ZFS will assign a unique digital fingerprint to it - the so-called checksum. The file will be synchronized between multiple SSD drives for redundancy, so if one drive fails, the other ones will take control. ZFS compares the checksum of all the copies on the different drives and if it detects a damaged copy, it replaces it with a healthy one from a different drive. This happens immediately, so there will be no threat for any part of your content at any moment. In comparison, all of the other file systems carry out checks after a system breakdown, but since they do not use anything similar to the checksums that ZFS uses, they can't detect silently corrupted files, so a corrupted copy may be replicated on the rest of the drives as well and you can lose crucial data. As this is not the case with ZFS, we guarantee the integrity of each and every file you upload no matter what.
