Data corruption is the damage of information caused by various software or hardware fails. After a file is corrupted, it will no longer work correctly, so an application will not start or will give errors, a text file could be partially or completely unreadable, an archive file 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 administrator, which makes it a significant problem for web hosting servers as failures are much more likely to occur on bigger hard disks where vast volumes of information are placed. In case a drive is a part of a RAID and the info on it is duplicated on other drives for redundancy, it is more than likely that the bad file will be treated as a regular one and will be duplicated on all of the drives, making the harm permanent. A huge number of the file systems which operate on web servers nowadays often are not able to recognize corrupted files right away or they need time-consuming system checks during which the server is not working.
No Data Corruption & Data Integrity in Hosting
We guarantee the integrity of the data uploaded in every single hosting account that is created on our cloud platform due to the fact that we work with the advanced ZFS file system. The latter is the only one which was designed to avoid silent data corruption through a unique checksum for each and every file. We will store your data on multiple NVMe drives that operate in a RAID, so identical files will be accessible on several places at once. ZFS checks the digital fingerprint of all the files on all the drives in real time and in the event that the checksum of any file is different from what it needs to be, the file system replaces that file with an undamaged version from another drive inside the RAID. There's no other file system that 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 won't have to concern yourself with the integrity of your information.
No Data Corruption & Data Integrity in Semi-dedicated Hosting
You won't need to deal with any kind of silent data corruption issues whatsoever in case you acquire one of our semi-dedicated hosting packages because the ZFS file system that we employ on our cloud hosting platform uses checksums to make sure that all the files are intact all of the time. A checksum is a unique digital fingerprint that is assigned to each and every file kept on a server. Due to the fact that we store all content on multiple drives simultaneously, 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 right away. In the event that 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 right away, avoiding any probability of the damaged copy to be synchronized on the rest of the hard disks. ZFS is the sole file system available on the market that uses checksums, which makes it much more reliable than other file systems which are not able to identify silent data corruption and copy bad files across hard drives.
