Data corruption is the damage of data because of various hardware or software failures. When a file gets damaged, it will no longer work accurately, so an app will not start or will give errors, a text file will be partially or fully unreadable, an archive file will be impossible to open then unpack, etc. Silent data corruption is the process of info getting damaged without any identification by the system or an administrator, which makes it a significant problem for hosting servers as failures are very likely to happen on bigger hard drives where vast volumes of info are kept. In case a drive is part of a RAID and the info on it is duplicated on other drives for redundancy, it is very likely that the damaged file will be treated as a regular one and it will be copied on all of the drives, making the damage permanent. A lot of the file systems that run on web servers nowadays often are unable to identify corrupted files in real time or they need time-consuming system checks during which the server is not working.

No Data Corruption & Data Integrity in Shared Hosting

We guarantee the integrity of the data uploaded in each shared hosting account that is made on our cloud platform due to the fact that we employ the advanced ZFS file system. The latter is the only one which was designed to avoid silent data corruption thanks to a unique checksum for each and every file. We'll store your info on multiple NVMe drives that work in a RAID, so exactly the same files will be present on several places simultaneously. ZFS checks the digital fingerprint of all files on all drives in real time and in the event that the checksum of any file differs from what it has to be, the file system swaps that file with an undamaged copy from another drive inside the RAID. There's no other file system which 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 this can never happen on a server running ZFS, you don't have to worry about the integrity of your information.

No Data Corruption & Data Integrity in Semi-dedicated Hosting

We've avoided any possibility of files getting corrupted silently as the servers where your semi-dedicated hosting account will be created employ a powerful file system named ZFS. Its advantage over alternative file systems is that it uses a unique checksum for each file - a digital fingerprint which is checked in real time. Since we store all content on multiple NVMe drives, ZFS checks whether the fingerprint of a file on one drive corresponds to the one on the other drives and the one it has saved. In the event that there is a mismatch, the corrupted copy is replaced with a healthy one from one of the other drives and since it happens in real time, there's no chance that a corrupted copy could remain on our hosting servers or that it could be copied to the other hard drives 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 electrical power failure, none of them can detect silently corrupted files. In comparison, ZFS will not crash after a blackout and the constant checksum monitoring makes a lenghty file system check obsolete.
