The process of files getting corrupted caused by some hardware or software failure is called data corruption and this is one of the main problems which web hosting companies face because the larger a hard disk is and the more information is placed on it, the much more likely it is for data to become corrupted. You will find different fail-safes, but often the data is corrupted silently, so neither the file system, nor the administrators see a thing. Because of this, a bad file will be handled as a regular one and if the hard disk drive is a part of a RAID, that particular file will be copied on all other disk drives. In theory, this is for redundancy, but in reality the damage will get even worse. Once a given file gets corrupted, it will be partially or completely 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, and you risk sacrificing your content. Although the most frequently used server file systems feature various checks, they frequently fail to find some problem early enough or require a long amount of time to be able to check all files and the server will not be operational in the meantime.
No Data Corruption & Data Integrity in Hosting
The integrity of the data that you upload to your new hosting
account shall be guaranteed by the ZFS file system that we take advantage of on our cloud platform. Most of the internet hosting service providers, including our company, use multiple hard drives to keep content and because the drives work in a RAID, identical info is synchronized between the drives at all times. In case a file on a drive gets damaged for whatever reason, however, it's very likely that it will be copied on the other drives because alternative file systems do not feature special checks for that. In contrast to them, ZFS employs a digital fingerprint, or a checksum, for each and every file. If a file gets corrupted, its checksum won't match what ZFS has as a record for it, so the bad copy shall be replaced with a good one from another drive. As this happens instantly, there's no risk for any of your files to ever be damaged.
No Data Corruption & Data Integrity in Semi-dedicated Servers
Your semi-dedicated server
account will be resistant to silent data corruption as all our storage servers use the efficient ZFS file system. What makes the aforementioned unique is that it uses checksums, or digital identifiers, in order to verify the integrity of every single file. When you upload content to your account, it'll be placed on a couple of redundant drives employed in a RAID i.e. the files will be the same on all drives. All of the copies of a given file will feature the same checksum on all hard drives and ZFS will compare the checksums of the copies right away, and if it registers a mismatch, that will indicate that one of the copies is corrupted, it'll swap that file with a good copy from one of the other drives. Even if there is an unforeseen blackout, the data on the servers will not get corrupted and there will not be any need for a time-consuming system check that other file systems perform after some failure, lengthening the time needed for the server to return online. ZFS is the sole file system which can really protect your content from silent data corruption.
