The process of files being corrupted resulting from some hardware or software failure is known as data corruption and this is among the main problems which hosting companies face since the larger a hard disk drive is and the more information is filed on it, the much more likely it is for data to get corrupted. You'll find several fail-safes, yet often the data is corrupted silently, so neither the particular file system, nor the admins detect a thing. As a result, a bad file will be treated as a regular one and if the hard disk is part of a RAID, that particular file will be copied on all other drives. Theoretically, this is done for redundancy, but in practice the damage will be worse. The moment some file gets damaged, it will be partially or fully unreadable, therefore a text file will no longer be readable, an image file will show a random combination 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 have various checks, they often fail to identify some problem early enough or require a vast time period to be able to check all the files and the hosting server will not be operational in the meantime.

No Data Corruption & Data Integrity in Semi-dedicated Servers

Your semi-dedicated server account will be protected against silent data corruption since all our storage servers use the reliable ZFS file system. What makes the aforementioned unique is that it employs checksums, or digital identifiers, to guarantee the integrity of each file. When you upload content to your account, it'll be stored on a couple of redundant drives in a RAID i.e. the files will be the same on all drives. All the copies of a given file will feature the same checksum on all hard disks and ZFS will compare the checksums of the copies right away, and if it discovers a mismatch, that would indicate that one of the copies is corrupted, it will swap that file with a healthy copy from one of the other disks. Even if there is a sudden power loss, the data on the servers won't be corrupted and there won't be any need for a time-consuming system check which other file systems perform after some failure, prolonging the time needed for the server to return online. ZFS is the file system that can really protect your content from silent data corruption.
