Data corruption is the damage of info caused by various software or hardware problems. The moment a file is corrupted, it will no longer function properly, so an application will not start or shall give errors, a text file will be partially or completely unreadable, an archive will be impossible to open then unpack, etc. Silent data corruption is the process of information getting harmed without any acknowledgement by the system or an administrator, which makes it a serious problem for website hosting servers as fails are very likely to happen on larger hard drives where significant volumes of information are placed. When a drive is part of a RAID and the data on it is replicated on other drives for redundancy, it is likely that the damaged file will be treated as an ordinary one and will be copied on all drives, making the harm permanent. A lot of the file systems which run on web servers nowadays often are not able to detect corrupted files in real time or they need time-consuming system checks during which the server is not functioning.

No Data Corruption & Data Integrity in Cloud Hosting

We warrant the integrity of the info uploaded in every single cloud hosting account which is created on our cloud platform since we use the advanced ZFS file system. The latter is the only one which was designed to avert silent data corruption thanks to a unique checksum for every single file. We shall store your information on multiple NVMe drives that work in a RAID, so the same files will be present on several places concurrently. ZFS checks the digital fingerprint of all of the files on all drives in real time and if the checksum of any file is different from what it needs to be, the file system replaces that file with a healthy version from a different drive inside the RAID. No other file system uses checksums, so it is possible for data to be silently damaged and the bad file to be replicated on all drives with time, but since that can never happen on a server using ZFS, you won't have to worry about the integrity of your data.

No Data Corruption & Data Integrity in Semi-dedicated Hosting

We've avoided any chance of files getting damaged silently since the servers where your semi-dedicated hosting account will be created employ a powerful file system named ZFS. Its basic advantage over alternative file systems is that it uses a unique checksum for every single file - a digital fingerprint that's checked in real time. As we save all content on numerous NVMe drives, ZFS checks if the fingerprint of a file on one drive matches the one on the rest of the drives and the one it has stored. When there is a mismatch, the damaged copy is replaced with a healthy one from one of the other drives and since it happens instantly, there's no chance that a damaged copy can remain on our hosting servers or that it could be duplicated to the other hard drives in the RAID. None of the other file systems use such checks and in addition, even during a file system check after an unexpected power loss, none of them will discover silently corrupted files. In comparison, ZFS won't crash after a blackout and the constant checksum monitoring makes a time-consuming file system check obsolete.
