Data corruption is the damage of data due to various software or hardware failures. Once a file is damaged, it will no longer work properly, so an application will not start or shall give errors, a text file could be partially or entirely unreadable, an archive file will be impossible to open and then unpack, etc. Silent data corruption is the process of information getting damaged without any acknowledgement by the system or an admin, that makes it a serious problem for website hosting servers as problems are more likely to happen on bigger hard disks where substantial volumes of info are stored. In case a drive is a part of a RAID and the info on it is duplicated on other drives for redundancy, it's very likely that the bad file will be treated as a healthy one and it will be copied on all of the drives, making the damage permanent. Lots of the file systems which run on web servers nowadays often are not able to discover 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 Hosting
We warrant the integrity of the info uploaded in each hosting account that is generated on our cloud platform due to the fact that we work with the advanced ZFS file system. The aforementioned is the only one that was designed to avert silent data corruption using a unique checksum for each file. We will store your info on a number of NVMe drives which operate in a RAID, so identical files will be available on several places at once. ZFS checks the digital fingerprint of all of the files on all 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 swaps that file with an undamaged version from another drive within the RAID. There's no other file system which uses checksums, so it is easy for data to get silently corrupted and the bad file to be reproduced on all drives with time, but since this can never happen on a server using ZFS, you do not have to concern yourself with the integrity of your info.
No Data Corruption & Data Integrity in Semi-dedicated Hosting
Your semi-dedicated hosting account will be protected against silent data corruption because all of our storage servers work with the effective ZFS file system. What makes the aforementioned unique is that it uses checksums, or digital identifiers, in order to guarantee the integrity of each and every file. When you upload content to your account, it will be placed on a couple of redundant drives in a RAID i.e. the files shall be the same on all disks. All copies of a particular file will feature the same checksum on all hard disks and ZFS will compare the checksums of the duplicates in real time, and if it identifies a mismatch, which would indicate that one of the copies is corrupted, it will swap that file with a healthy copy from one of the other drives. Even if there is an unforeseen power loss, the data on the servers will not become corrupted and there won't be any need for a time-consuming system check which other file systems perform following some malfunction, extending the time needed for the server to go back online. ZFS is the only file system which can truly protect your content from silent data corruption.
