Data corruption is the damage of info caused by various hardware or software failures. When a file is damaged, it will no longer work properly, so an app will not start or will give errors, a text file will be partially or fully unreadable, an archive will be impossible to open then unpack, etc. Silent data corruption is the process of information getting harmed without any acknowledgement by the system or an admin, that makes it a significant problem for hosting servers as problems are more likely to happen on larger in size hard drives where significant volumes of info are kept. If a drive is part of a RAID and the info on it is replicated on other drives for redundancy, it is more than likely that the damaged file will be treated as an ordinary one and it'll be copied on all the drives, making the damage permanent. Lots of the file systems that operate on web servers today often are not able to locate corrupted files immediately or they need time-consuming system checks through which the server is not working.

No Data Corruption & Data Integrity in Hosting

We warrant the integrity of the information uploaded in every single hosting account that is generated on our cloud platform because we use the advanced ZFS file system. The aforementioned is the only one that was designed to avoid silent data corruption thanks to a unique checksum for each and every file. We'll store your information on a number of SSD drives which operate in a RAID, so identical files will exist 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 is different from what it needs to be, the file system replaces that file with a healthy copy from a different drive within the RAID. No other file system uses checksums, so it is possible for data to be silently corrupted and the bad file to be duplicated on all drives over time, but since that 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 will not have to deal with any silent data corruption issues whatsoever if you get one of our semi-dedicated server plans due to the fact that the ZFS file system that we employ on our cloud hosting platform uses checksums in order to make sure that all the files are intact all of the time. A checksum is a unique digital fingerprint which is assigned to each and every file saved on a server. Since we store all content on a number of drives at the same time, 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. 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 without delay, avoiding any possibility of the bad copy to be synchronized on the other hard disks. ZFS is the only file system out there that uses checksums, which makes it much more reliable than other file systems that are unable to detect silent data corruption and duplicate bad files across hard drives.
