The process of files being damaged caused by some hardware or software failure is known as data corruption and this is one of the main problems that web hosting companies face because the larger a hard disk drive is and the more data is kept on it, the more likely it is for data to be corrupted. You will find several fail-safes, yet often the information gets damaged silently, so neither the file system, nor the administrators notice anything. As a result, a bad file will be handled as a standard one and if the HDD is a part of a RAID, the file will be copied on all other drives. In principle, this is for redundancy, but in reality the damage will be even worse. When a file gets damaged, it will be partially or entirely unreadable, which means that a text file will not be readable, an image file will present a random mix of colors in case it opens at all and an archive will be impossible to unpack, so you risk sacrificing your site content. Although the most popular server file systems have various checks, they often fail to discover a problem early enough or require a vast amount of time to be able to check all the files and the hosting server will not be functional in the meantime.

No Data Corruption & Data Integrity in Cloud Hosting

The integrity of the data that you upload to your new cloud hosting account will be ensured by the ZFS file system that we employ on our cloud platform. The majority of web hosting service providers, including our company, use multiple HDDs to keep content and since the drives work in a RAID, the exact same info is synchronized between the drives all the time. If a file on a drive becomes damaged for whatever reason, however, it's more than likely that it will be reproduced on the other drives because other file systems do not feature special checks for that. In contrast to them, ZFS works with a digital fingerprint, or a checksum, for each file. In the event that a file gets corrupted, its checksum won't match what ZFS has as a record for it, so the damaged copy will be swapped with a good one from another disk drive. As this happens in real time, there is no risk for any of your files to ever get corrupted.

No Data Corruption & Data Integrity in Semi-dedicated Servers

You won't have to deal with any silent data corruption issues should you get one of our semi-dedicated server solutions since the ZFS file system that we use on our cloud hosting platform uses checksums to ensure that all of the files are undamaged all of the time. A checksum is a unique digital fingerprint that is allotted to each and every file kept on a server. As we store all content on a number of drives at the same time, the same file uses the same checksum on all the drives and what ZFS does is that it compares the checksums between the different drives in real time. When it detects that a file is corrupted and its checksum is different from what it should be, it replaces that file with a healthy copy right away, avoiding any chance of the bad copy to be synchronized on the other drives. ZFS is the only file system you can find that uses checksums, which makes it much more reliable than other file systems that are unable to identify silent data corruption and copy bad files across hard drives.
