The process of files getting damaged due to some hardware or software failure is referred to as data corruption and this is one of the main problems which Internet hosting companies face because the larger a hard disk drive is and the more info is filed on it, the much more likely it is for data to become corrupted. You can find various fail-safes, yet often the information is damaged silently, so neither the file system, nor the administrators notice anything. Consequently, a damaged file will be handled as a regular one and if the hard disk is a part of a RAID, the file will be duplicated on all other drives. Theoretically, this is for redundancy, but in practice the damage will get worse. The moment some file gets corrupted, it will be partially or completely unreadable, therefore a text file will no longer be readable, an image file will show a random blend of colors in case it opens at all and an archive will be impossible to unpack, so you risk losing your website content. Although the most commonly used server file systems include various checks, they frequently fail to detect a problem early enough or require a long time period to be able to check all of the files and the hosting server will not be functional in the meantime.
No Data Corruption & Data Integrity in Cloud Website Hosting
If you host your websites in a cloud website hosting
account from our company, you don't have to worry about any of your data ever getting damaged. We can ensure that due to the fact that our cloud hosting platform uses the amazing ZFS file system. The aforementioned is the only file system that uses checksums, or unique digital fingerprints, for each and every file. All of the info that you upload will be kept in a RAID i.e. simultaneously on a number of SSDs. A lot of file systems synchronize the files between the different drives with this type of a setup, but there's no real guarantee that a file won't get corrupted. This could occur throughout the writing process on any drive and after that a damaged copy may be copied on the other drives. What makes the difference on our platform is that ZFS examines the checksums of all files on all drives live and when a corrupted file is found, it's replaced with a good copy with the correct checksum from some other drive. In this way, your info will remain unharmed no matter what, even if a whole drive fails.
No Data Corruption & Data Integrity in Semi-dedicated Servers
We have avoided any risk of files getting damaged silently as the servers where your semi-dedicated server
account will be created take advantage of a powerful file system named ZFS. Its key advantage over alternative file systems is that it uses a unique checksum for each and every file - a digital fingerprint that's checked in real time. As we store all content on numerous SSD drives, ZFS checks whether the fingerprint of a file on one drive matches the one on the other drives and the one it has saved. If there is a mismatch, the corrupted copy is replaced with a healthy one from one of the other drives and considering that this happens instantly, there's no chance that a damaged copy could remain on our web servers or that it could be copied to the other hard disks in the RAID. None of the other file systems include such checks and in addition, even during a file system check after a sudden power failure, none of them can identify silently corrupted files. In comparison, ZFS will not crash after a blackout and the constant checksum monitoring makes a time-consuming file system check obsolete.
