Data corruption is the damage of info caused by various hardware or software problems. After a file is damaged, it will no longer function accurately, so an application will not start or will give errors, a text file can be partially or fully unreadable, an archive will be impossible to open and unpack, etc. Silent data corruption is the process of data getting damaged without any identification by the system or an admin, which makes it a significant problem for web hosting servers as fails are much more likely to occur on larger hard disks where substantial volumes of information are located. If a drive is part of a RAID and the data on it is duplicated on other drives for redundancy, it's more than likely that the bad file will be treated as an undamaged one and will be duplicated on all of the drives, making the harm permanent. A lot of the file systems which operate on web servers today often cannot detect corrupted files in real time or they need time-consuming system checks through which the server isn't operational.

No Data Corruption & Data Integrity in Shared Hosting

We guarantee the integrity of the info uploaded in every shared hosting account which is generated on our cloud platform as we use the advanced ZFS file system. The latter is the only one which was designed to prevent silent data corruption through a unique checksum for each file. We'll store your data on a number of SSD drives which operate in a RAID, so the same files will be accessible on several places at the same time. ZFS checks the digital fingerprint of all files on all drives in real time and if the checksum of any file is different from what it should be, the file system swaps that file with an undamaged version from a different drive in the RAID. There's no other file system that uses checksums, so it is possible for data to get silently damaged and the bad file to be duplicated on all drives over time, but since that can never happen on a server running ZFS, you will not have to worry about the integrity of your data.

No Data Corruption & Data Integrity in Semi-dedicated Hosting

You will not experience any kind of silent data corruption issues should you obtain one of our semi-dedicated hosting solutions because the ZFS file system that we use on our cloud hosting platform uses checksums in order to guarantee that all of the files are intact all the time. A checksum is a unique digital fingerprint which is allotted to each and every file kept on a server. Because we store all content on multiple drives at the same time, the same file uses the same checksum on all of the drives and what ZFS does is that it compares the checksums between the different drives in real time. If it detects that a file is corrupted and its checksum is different from what it should be, it replaces that file with a healthy copy without delay, avoiding any chance of the corrupted copy to be synchronized on the rest of the hard disks. ZFS is the sole file system you can get which uses checksums, which makes it much more reliable than other file systems that are not able to detect silent data corruption and duplicate bad files across drives.
