Data corruption is the damage of data caused by various software or hardware problems. Once a file is corrupted, it will no longer work accurately, so an app will not start or will give errors, a text file shall be partially or entirely unreadable, an archive file 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 web hosting servers as fails are very likely to happen on larger in size hard disk drives where considerable volumes of info are located. In case a drive is part of a RAID and the data on it is duplicated on other drives for redundancy, it's very likely that the damaged file will be treated as a healthy one and it'll be duplicated on all the drives, making the harm permanent. A lot of the file systems that run on web servers today often cannot detect corrupted files immediately or they need time-consuming system checks during which the server is not functioning.

No Data Corruption & Data Integrity in Shared Web Hosting

We warrant the integrity of the info uploaded in each shared web hosting account that is created on our cloud platform due to the fact that we use the advanced ZFS file system. The latter is the only one that was designed to prevent silent data corruption using a unique checksum for each and every file. We shall store your information on a large number of NVMe drives which work in a RAID, so the very same files will be accessible on several places concurrently. ZFS checks the digital fingerprint of all the files on all the drives in real time and if 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 be silently corrupted and the bad file to be replicated on all drives with time, but since this 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 Servers

You won't encounter any kind of silent data corruption issues should you get one of our semi-dedicated server packages because the ZFS file system that we take advantage of on our cloud hosting platform uses checksums in order to make sure that all files are undamaged all the time. A checksum is a unique digital fingerprint that is given to each and every file kept on a server. Since we store all content on a number of drives simultaneously, the same file has the same checksum on all of the drives and what ZFS does is that it compares the checksums between the different drives right away. If it detects that a file is corrupted and its checksum is different from what it has to be, it replaces that file with a healthy copy right away, avoiding any probability of the corrupted copy to be synchronized on the rest of the drives. ZFS is the sole file system out there that uses checksums, which makes it much more dependable than other file systems that are not able to identify silent data corruption and duplicate bad files across drives.
