Data corruption is the damage of info due to various hardware or software problems. The moment a file is corrupted, it will no longer work correctly, so an app will not start or shall give errors, a text file will be partially or entirely unreadable, an archive will be impossible to open then unpack, etc. Silent data corruption is the process of info getting harmed without any acknowledgement by the system or an administrator, that makes it a serious problem for hosting servers as problems are very likely to happen on bigger hard disks where large volumes of info are placed. When a drive is a part of a RAID and the information on it is duplicated on other drives for redundancy, it is very likely that the damaged file will be treated as a good one and will be copied on all of the drives, making the harm permanent. Lots of the file systems which run on web servers these days often are unable to recognize corrupted files in real time or they need time-consuming system checks through which the server isn't working.

No Data Corruption & Data Integrity in Shared Website Hosting

We guarantee the integrity of the info uploaded in each shared website hosting account that is created on our cloud platform since we work with the advanced ZFS file system. The aforementioned is the only one that was designed to avert silent data corruption through a unique checksum for each file. We will store your information on a number of NVMe drives which work in a RAID, so the very same files will exist on several places concurrently. ZFS checks the digital fingerprint of all the files on all drives in real time and in the event that the checksum of any file is different from what it should be, the file system replaces that file with an undamaged version from a different drive from the RAID. No other file system uses checksums, so it's possible for data to get silently corrupted and the bad file to be replicated on all drives over time, but since that can never happen on a server using ZFS, you will not have to worry about the integrity of your info.

No Data Corruption & Data Integrity in Semi-dedicated Servers

We've avoided any possibility of files getting damaged silently because the servers where your semi-dedicated server account will be created use a powerful file system named ZFS. Its advantage over other file systems is that it uses a unique checksum for each file - a digital fingerprint that's checked in real time. As we save all content on a number of NVMe drives, ZFS checks if the fingerprint of a file on one drive matches the one on the other drives and the one it has saved. In the event that there's a mismatch, the bad copy is replaced with a healthy one from one of the other drives and since this happens right away, there is no chance that a damaged copy can remain on our web servers or that it could be duplicated to the other hard disks in the RAID. None of the other file systems use this kind of checks and what is more, even during a file system check after an unexpected power loss, none of them can discover silently corrupted files. In contrast, ZFS won't crash after an electrical power failure and the constant checksum monitoring makes a lenghty file system check unneeded.
