The process of files being damaged as a result of some hardware or software failure is referred to as data corruption and this is one of the main problems that web hosting companies face as the larger a hard disk is and the more data is placed on it, the more likely it is for data to be corrupted. You will find a couple of fail-safes, still often the info gets corrupted silently, so neither the particular file system, nor the admins see a thing. As a result, a corrupted file will be treated as a good one and if the hard drive is a part of a RAID, that particular file will be copied on all other disk drives. In theory, this is done for redundancy, but in practice the damage will get worse. The moment a file gets damaged, it will be partially or fully unreadable, which means that a text file will not be readable, an image file will present a random mix of colors if it opens at all and an archive will be impossible to unpack, and you risk losing your website content. Although the most commonly used server file systems have various checks, they are likely to fail to detect some problem early enough or require a vast period of time in order to check all of the files and the web server will not be operational in the meantime.

No Data Corruption & Data Integrity in Cloud Web Hosting

If you host your sites in a cloud web hosting account with our firm, you don't have to worry about any of your data ever getting corrupted. We can ensure that as our cloud hosting platform works with the reliable ZFS file system. The aforementioned is the only file system which uses checksums, or unique digital fingerprints, for each file. Any info that you upload will be kept in a RAID i.e. simultaneously on many SSD drives. All file systems synchronize the files between the different drives using such a setup, but there's no real guarantee that a file will not get corrupted. This can happen during the writing process on any drive and after that a corrupted copy may be copied on the other drives. What is different on our platform is that ZFS compares the checksums of all files on all of the drives live and if a corrupted file is discovered, it is substituted with a good copy with the correct checksum from another drive. In this way, your data will continue to be intact no matter what, even if an entire drive fails.

No Data Corruption & Data Integrity in Semi-dedicated Servers

Your semi-dedicated server account will be protected against silent data corruption as all of our storage servers work with the effective ZFS file system. What makes the latter unique is that it uses checksums, or digital identifiers, in order to guarantee the integrity of each and every file. When you upload content to your account, it'll be saved on a couple of redundant drives employed in a RAID i.e. the files shall be the same on all disk drives. All the copies of a specific file will feature the same checksum on all drives and ZFS will compare the checksums of the copies right away, and if it finds a mismatch, which will indicate that one of the copies is damaged, it'll swap that file with a good copy from one of the other disks. Even if there is a sudden blackout, the data on the servers won't become corrupted and there will not be any need for a time-consuming system check that other file systems perform following some malfunction, extending the time needed for the server to get back online. ZFS is the only file system which can truly protect your content from silent data corruption.
