The process of files getting damaged resulting from 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 is and the more data is kept on it, the more likely it is for data to become corrupted. There are a couple of fail-safes, yet often the information is damaged silently, so neither the particular file system, nor the administrators detect a thing. Consequently, a damaged file will be treated as a standard one and if the hard disk drive is a part of a RAID, the file will be duplicated on all other drives. In theory, this is done for redundancy, but in reality the damage will be worse. When some file gets damaged, it will be partially or fully unreadable, which means that 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 shall be impossible to unpack, so you risk sacrificing your website content. Although the most widely used server file systems include various checks, they are likely to fail to find some problem early enough or require a long time period to be able to check all 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 ensured by the ZFS file system that we work with on our cloud platform. The vast majority of web hosting suppliers, including our company, use multiple HDDs to keep content and because the drives work in a RAID, exactly the same data is synchronized between the drives all the time. When a file on a drive gets damaged for reasons unknown, however, it is more than likely that it will be reproduced on the other drives since other file systems don't have special checks for that. In contrast to them, ZFS uses 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, and the bad copy will be replaced with a good one from another hard drive. Due to the fact that this happens right away, there is no risk for any of your files to ever be corrupted.
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 make use of the reliable ZFS file system. What makes the latter unique is that it uses checksums, or digital identifiers, in order to ensure the integrity of every single file. When you upload content to your account, it'll be placed on several redundant drives working in a RAID i.e. the files will be the same on all disks. All copies of a specific file will feature the same checksum on all drives and ZFS will compare the checksums of the copies quickly, and if it identifies a mismatch, that will indicate that one of the copies is damaged, it will swap that file with a healthy copy from one of the other disks. Even if there is an unexpected blackout, the data on the servers won't be corrupted and there won't be any need for a time-consuming system check that other file systems perform after some malfunction, lengthening the time needed for the server to get back online. ZFS is the only file system which can really protect your content from silent data corruption.
