Data corruption is the damage of info due to various software or hardware problems. After a file is damaged, it will no longer function properly, so an application will not start or will give errors, a text file will be partially or completely unreadable, an archive file will be impossible to open 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 significant problem for hosting servers as failures are very likely to happen on larger hard disk drives where large volumes of information are stored. When a drive is part of a RAID and the info on it is copied on other drives for redundancy, it is more than likely that the bad file will be treated as an ordinary one and it'll be duplicated on all drives, making the damage permanent. Lots of the file systems which run on web servers nowadays often cannot recognize corrupted files immediately or they need time-consuming system checks through which the server isn't functioning.
No Data Corruption & Data Integrity in Cloud Hosting
We guarantee the integrity of the info uploaded in each cloud hosting
account which is created on our cloud platform due to the fact that we employ the advanced ZFS file system. The aforementioned is the only one that was designed to avert silent data corruption thanks to a unique checksum for every single file. We will store your info on a large number of SSD drives that work in a RAID, so the exact same files will be present on several places at the same time. ZFS checks the digital fingerprint of all 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 a healthy version from another drive within the RAID. No other file system uses checksums, so it is possible for data to get silently damaged and the bad file to be duplicated on all drives with time, but since this can never happen on a server running ZFS, you won't have to worry about the integrity of your information.
No Data Corruption & Data Integrity in Semi-dedicated Hosting
You will not have to deal with any silent data corruption issues in case you buy one of our semi-dedicated hosting
solutions as the ZFS file system that we employ on our cloud hosting platform uses checksums in order to ensure that all of your files are intact at all times. A checksum is a unique digital fingerprint that is assigned to each and every file kept on a server. Since we store all content on a number of 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 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 chance of the bad copy to be synchronized on the rest of the drives. ZFS is the sole file system you can get which uses checksums, which makes it much more dependable than other file systems which are unable to identify silent data corruption and copy bad files across hard drives.
