Data corruption is the unintentional transformation of a file or the losing of information which usually occurs during reading or writing. The reason can be hardware or software fail, and due to this fact, a file may become partially or fully corrupted, so it will no longer function correctly since its bits will be scrambled or lost. An image file, for instance, will no longer show an actual image, but a random mix of colors, an archive will be impossible to unpack because its content will be unreadable, etcetera. In the event that such an issue occurs and it's not identified by the system or by an admin, the data will get corrupted silently and if this happens on a disk drive that's a part of a RAID array where the info is synchronized between different drives, the corrupted file shall be reproduced on all other drives and the damage will become permanent. A number of frequently used file systems either don't offer real-time checks or do not have good ones which can detect an issue before the damage is done, so silent data corruption is a rather common issue on internet hosting servers where substantial volumes of information are stored.
No Data Corruption & Data Integrity in Web Hosting
We guarantee the integrity of the data uploaded in every single web hosting account that is made on our cloud platform since we use the advanced ZFS file system. The latter is the only one which was designed to avert silent data corruption thanks to a unique checksum for each file. We shall store your information on a large number of SSD drives that function in a RAID, so exactly the same files will be available on several places at once. ZFS checks the digital fingerprint of all the files on all drives in real time and in case the checksum of any file is different from what it should 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 get 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 will not have to worry about the integrity of your info.
No Data Corruption & Data Integrity in Semi-dedicated Servers
You won't experience any kind of silent data corruption issues whatsoever in case you get one of our semi-dedicated server solutions because the ZFS file system that we work with on our cloud hosting platform uses checksums in order to make sure that all of the files are undamaged at all times. A checksum is a unique digital fingerprint which is given to each and every file kept on a server. Since we store all content on a number of drives simultaneously, the same file uses the same checksum on all drives and what ZFS does is that it compares the checksums between the different drives right away. If 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 rest of the hard drives. ZFS is the sole file system you will find that uses checksums, which makes it much more reliable than other file systems that cannot identify silent data corruption and copy bad files across drives.
