Data corruption is the accidental modification of a file or the losing of info that usually occurs during reading or writing. The reason could be hardware or software failure, and due to this fact, a file can become partially or completely corrupted, so it'll no longer work correctly as its bits will be scrambled or lost. An image file, for example, will no longer present an actual image, but a random mix of colors, an archive will be impossible to unpack since its content will be unreadable, and so on. In case such a problem appears and it isn't noticed by the system or by an administrator, the data will get corrupted silently and in case this happens on a disk drive that's part of a RAID array where the information is synced between various different drives, the corrupted file will be reproduced on all the other drives and the harm will be permanent. A large number of frequently used file systems either do not have real-time checks or do not have high quality ones which will detect an issue before the damage is done, so silent data corruption is a common issue on internet hosting servers where large amounts of information are kept.
No Data Corruption & Data Integrity in Shared Website Hosting
We warrant the integrity of the info uploaded in every shared website hosting
account that is generated on our cloud platform as we work with the advanced ZFS file system. The aforementioned is the only one that was designed to prevent silent data corruption thanks to a unique checksum for every single file. We shall store your data on a large number of SSD drives that operate in a RAID, so exactly the same files will be accessible on several places concurrently. ZFS checks the digital fingerprint of all the files on all of the drives in real time and if the checksum of any file differs from what it should be, the file system swaps that file with an undamaged version from some other drive inside 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 don't have to worry about the integrity of your info.
No Data Corruption & Data Integrity in Semi-dedicated Servers
We've avoided any risk of files getting damaged silently as the servers where your semi-dedicated server
account will be created work with a powerful file system named ZFS. Its basic advantage over various other file systems is that it uses a unique checksum for each file - a digital fingerprint which is checked in real time. Since we save all content on numerous SSD drives, ZFS checks if the fingerprint of a file on one drive matches the one on the remaining drives and the one it has saved. In the event that there's a mismatch, the damaged copy is replaced with a good one from one of the other drives and since this happens in real time, there's no chance that a corrupted copy could remain on our web hosting servers or that it could be duplicated to the other drives in the RAID. None of the other file systems employ this type of checks and in addition, even during a file system check right after a sudden electrical power failure, none of them will identify silently corrupted files. In comparison, ZFS will not crash after a power loss and the regular checksum monitoring makes a time-consuming file system check unneeded.
