Data corruption is the damage of info due to various hardware or software fails. The moment a file gets corrupted, it will no longer function correctly, so an app will not start or shall give errors, a text file shall be partially or fully unreadable, an archive will be impossible to open and unpack, etc. Silent data corruption is the process of info getting damaged without any identification by the system or an administrator, that makes it a serious problem for web hosting servers as failures are very likely to happen on larger in size hard disks where vast volumes of info are placed. In case a drive is a part of a RAID and the information on it is replicated on other drives for redundancy, it's very likely that the damaged file will be treated as an undamaged one and it'll be copied on all of the drives, making the damage permanent. Lots of the file systems which run on web servers today often are unable to locate corrupted files instantly or they need time-consuming system checks through which the server isn't operational.

No Data Corruption & Data Integrity in Cloud Hosting

We warrant the integrity of the data uploaded in each and every cloud hosting account which is generated on our cloud platform due to the fact that we employ the advanced ZFS file system. The aforementioned is the only one that was designed to avert silent data corruption thanks to a unique checksum for each file. We will store your information on multiple SSD drives that function in a RAID, so the exact same files will be accessible on several places simultaneously. ZFS checks the digital fingerprint of all the files on all of the drives in real time and in case the checksum of any file differs from what it needs to be, the file system replaces that file with an undamaged version from another drive within the RAID. There's no other file system that uses checksums, so it is possible for data to become silently damaged and the bad file to be replicated on all drives with time, but since that can never happen on a server running ZFS, you do not have to worry about the integrity of your data.

No Data Corruption & Data Integrity in Semi-dedicated Hosting

If you buy one of our semi-dedicated hosting plans, you will not need to be concerned about silent file corruption as we use ZFS - an advanced file system which keeps track of all 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. That file will be synced between several 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 when it detects a corrupted copy, it replaces it with a healthy one from a different drive. This is done right away, so there will be no risk for any part of your content at any time. By comparison, other file systems execute checks after a system failure, but since they don't use anything similar to the checksums which ZFS uses, they won't detect silently corrupted files, so a corrupted copy can be replicated on the other drives as well and you can lose precious data. Because this is not the case with ZFS, we are able to warrant the integrity of each and every file you upload no matter what.
