The process of files getting corrupted due to some hardware or software failure is known as data corruption and this is among the main problems which Internet hosting companies face because the larger a hard disk is and the more information is filed on it, the more likely it is for data to be corrupted. There are different fail-safes, yet often the data becomes damaged silently, so neither the file system, nor the admins notice anything. Consequently, a bad file will be handled as a good one and if the hard disk drive is a part of a RAID, that file will be duplicated on all other disk drives. Theoretically, this is done for redundancy, but in reality the damage will get even worse. Once a given file gets corrupted, it will be partly or fully unreadable, therefore a text file will no longer be readable, an image file will present a random blend of colors if it opens at all and an archive shall be impossible to unpack, and you risk sacrificing your site content. Although the most widespread server file systems feature various checks, they frequently fail to identify a problem early enough or require a vast time period in order to check all of the files and the server will not be functional for the time being.
No Data Corruption & Data Integrity in Hosting
If you host your websites in a hosting account from our firm, you do not have to worry about your data ever getting damaged. We can ensure that as our cloud hosting platform works with the outstanding ZFS file system. The aforementioned is the only file system that uses checksums, or unique digital fingerprints, for each file. All the information that you upload will be saved in a RAID i.e. simultaneously on a number of NVMe drives. All file systems synchronize the files between the different drives using this type of a setup, but there is no real warranty that a file will not get corrupted. This may occur during the writing process on each drive and after that a damaged copy can be copied on the other drives. What is different on our platform is that ZFS compares the checksums of all files on all the drives instantly and in case a corrupted file is located, it is replaced with a good copy with the correct checksum from some other drive. By doing this, your information will continue to be intact no matter what, even if a whole drive fails.
No Data Corruption & Data Integrity in Semi-dedicated Hosting
We've avoided any probability of files getting corrupted silently because the servers where your semi-dedicated hosting account will be created work with a powerful file system called ZFS. Its main advantage over other file systems is that it uses a unique checksum for each file - a digital fingerprint that is checked in real time. Since we store all content on a number of NVMe drives, ZFS checks whether the fingerprint of a file on one drive corresponds to the one on the remaining drives and the one it has stored. In the event that there's a mismatch, the bad copy is replaced with a good one from one of the other drives and since it happens instantly, there's no chance that a corrupted copy can remain on our web servers or that it can be duplicated to the other hard disks in the RAID. None of the other file systems employ such checks and what's more, even during a file system check after an unexpected electrical power failure, none of them can find silently corrupted files. In comparison, ZFS does not crash after an electrical power failure and the continual checksum monitoring makes a time-consuming file system check unneeded.
