The process of files getting corrupted as a result of some hardware or software failure is referred to as data corruption and this is one of the main problems which web hosting companies face because the larger a hard disk drive is and the more info is kept on it, the much more likely it is for data to get corrupted. You will find different fail-safes, yet often the info gets corrupted silently, so neither the particular file system, nor the administrators see a thing. Because of this, a bad file will be treated as a good one and if the hard disk is part of a RAID, that particular file will be duplicated on all other disk drives. In principle, this is done for redundancy, but in reality the damage will get even worse. When a file gets damaged, it will be partly or entirely unreadable, therefore a text file will no longer be readable, an image file will present a random mix of colors in case it opens at all and an archive shall be impossible to unpack, so you risk losing your site content. Although the most widely used server file systems include various checks, they quite often fail to find some problem early enough or require a vast time period to check all the files and the web server will not be functional for the time being.
No Data Corruption & Data Integrity in Shared Web Hosting
If you host your Internet sites in a shared web hosting
account with our company, you do not need to worry about your data ever getting damaged. We can guarantee that as our cloud hosting platform works with the cutting-edge ZFS file system. The latter is the only file system which works with checksums, or unique digital fingerprints, for every single file. All the data that you upload will be kept in a RAID i.e. simultaneously on numerous SSD drives. All of the file systems synchronize the files between the separate drives using this type of a setup, but there is no real guarantee that a file won't be corrupted. This could happen during the writing process on any drive and afterwards a bad copy may be copied on the rest of the drives. What makes the difference on our platform is the fact that ZFS compares the checksums of all files on all drives instantly and in case a corrupted file is identified, it is substituted with a good copy with the correct checksum from some other drive. In this way, your data will stay intact no matter what, even if an entire drive fails.
No Data Corruption & Data Integrity in Semi-dedicated Hosting
We have avoided any possibility of files getting corrupted silently since the servers where your semi-dedicated hosting
account will be created work with a powerful file system known as ZFS. Its advantage over various other file systems is that it uses a unique checksum for each and every file - a digital fingerprint which is checked in real time. As we save all content on multiple SSD drives, ZFS checks whether the fingerprint of a file on one drive corresponds to the one on the rest of the drives and the one it has saved. In case there's a mismatch, the corrupted copy is replaced with a healthy one from one of the other drives and since it happens right away, there is no chance that a corrupted copy can remain on our servers or that it can be copied to the other hard disks in the RAID. None of the other file systems include this type of checks and in addition, even during a file system check after a sudden power failure, none of them can find silently corrupted files. In comparison, ZFS won't crash after an electrical power failure and the constant checksum monitoring makes a lenghty file system check unneeded.
