Data corruption is the damage of information because of various hardware or software failures. When a file is damaged, it will no longer work accurately, so an app will not start or will give errors, a text file can be partially or entirely unreadable, an archive will be impossible to open and then unpack, etc. Silent data corruption is the process of info getting harmed without any acknowledgement by the system or an admin, that makes it a significant problem for website hosting servers as failures are very likely to happen on bigger hard drives where considerable volumes of info are located. If a drive is a part of a RAID and the info on it is duplicated on other drives for redundancy, it's more than likely that the bad file will be treated as a good one and it'll be copied on all of the drives, making the harm permanent. A huge number of the file systems which operate on web servers today often are not able to discover corrupted files in real time or they need time-consuming system checks during which the server isn't operational.
No Data Corruption & Data Integrity in Shared Hosting
We warrant the integrity of the data uploaded in any shared hosting
account which is made on our cloud platform due to the fact that we employ the advanced ZFS file system. The latter is the only one that was designed to avoid silent data corruption via a unique checksum for each file. We will store your data on multiple SSD drives which work in a RAID, so the exact same files will be present on several places simultaneously. ZFS checks the digital fingerprint of all the files on all of the drives in real time and in the event that the checksum of any file is different from what it has to be, the file system replaces that file with a healthy copy from another drive inside the RAID. There's no other file system that uses checksums, so it is possible for data to be silently corrupted and the bad file to be reproduced on all drives over time, but since that 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 Servers
You will not experience any kind of silent data corruption issues whatsoever in case you buy one of our semi-dedicated server
solutions because the ZFS file system that we work with on our cloud hosting platform uses checksums to make sure that all files are intact all the time. A checksum is a unique digital fingerprint that is assigned to each and every file kept on a server. As we store all content on multiple drives at the same time, the same file has the same checksum on all the drives and what ZFS does is that it compares the checksums between the different drives in real time. When 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 chance of the corrupted copy to be synchronized on the other hard drives. ZFS is the sole file system you can find that uses checksums, which makes it far superior to other file systems which are not able to detect silent data corruption and copy bad files across hard drives.
