The process of files getting damaged caused by some hardware or software failure is known as data corruption and this is among the main problems that web hosting companies face since the larger a hard disk drive is and the more data is kept on it, the much more likely it is for data to be corrupted. You will find several fail-safes, yet often the information becomes damaged silently, so neither the file system, nor the administrators notice a thing. Thus, a bad file will be handled as a regular one and if the hard disk is a part of a RAID, that particular file will be duplicated on all other drives. In principle, this is done for redundancy, but in reality the damage will get even worse. When a given 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 blend of colors if it opens at all and an archive will be impossible to unpack, and you risk losing your site content. Although the most commonly used server file systems include various checks, they quite often fail to identify some problem early enough or require a vast amount of time to be able to check all the files and the server will not be operational in the meantime.

No Data Corruption & Data Integrity in Shared Hosting

The integrity of the data which you upload to your new shared hosting account will be guaranteed by the ZFS file system that we take advantage of on our cloud platform. The vast majority of internet hosting providers, including our company, use multiple HDDs to keep content and because the drives work in a RAID, identical information is synchronized between the drives at all times. In case a file on a drive is damaged for reasons unknown, yet, it's very likely that it will be reproduced on the other drives since other file systems don't offer special checks for this. Unlike them, ZFS uses a digital fingerprint, or a checksum, for each and every file. If a file gets corrupted, its checksum will not match what ZFS has as a record for it, which means that the bad copy will be substituted with a good one from another disk drive. Because this happens instantly, there is no possibility for any of your files to ever get corrupted.

No Data Corruption & Data Integrity in Semi-dedicated Hosting

Your semi-dedicated hosting account will be resistant to silent data corruption as all our storage servers work with the reliable ZFS file system. What makes the latter unique is that it employs checksums, or digital identifiers, to guarantee the integrity of every single file. When you upload content to your account, it will be stored on a couple of redundant drives working in a RAID i.e. the files will be the same across all disk drives. All of the copies of a given file will have the same checksum on all hard drives and ZFS will compare the checksums of the duplicates right away, and if it detects a mismatch, which will indicate that one of the copies is damaged, it'll swap that file with a healthy copy from one of the other drives. Even if there is a sudden power loss, the data on the servers won't be corrupted and there will not be any need for a time-consuming system check that other file systems perform after some failure, extending the time needed for the server to go back online. ZFS is the file system which can truly protect your content from silent data corruption.
