Data corruption is the damage of info due to various hardware or software fails. Once a file gets damaged, it will no longer function properly, so an application will not start or will give errors, a text file can be partially or completely unreadable, an archive file will be impossible to open and unpack, etc. Silent data corruption is the process of info getting damaged without any acknowledgement by the system or an admin, that makes it a significant problem for web hosting servers as fails are more likely to happen on larger hard disks where large volumes of information are placed. If a drive is a part of a RAID and the data on it is replicated on other drives for redundancy, it is likely that the damaged file will be treated as a standard one and it'll be copied on all of the drives, making the harm permanent. A huge number of the file systems which operate on web servers these days often are not able to recognize corrupted files immediately or they need time-consuming system checks during which the server is not working.
No Data Corruption & Data Integrity in Web Hosting
The integrity of the data which you upload to your new web hosting
account shall be ensured by the ZFS file system that we make use of on our cloud platform. The vast majority of web hosting suppliers, including our firm, use multiple hard drives to store content and since the drives work in a RAID, identical data is synchronized between the drives all the time. When a file on a drive is corrupted for some reason, yet, it's very likely that it will be copied on the other drives since other file systems don't offer special checks for that. In contrast to them, ZFS applies a digital fingerprint, or a checksum, for every single file. In the event that a file gets damaged, its checksum won't match what ZFS has as a record for it, so the damaged copy will be substituted with a good one from a different hard drive. Because this happens in real time, there's no possibility for any of your files to ever be damaged.
No Data Corruption & Data Integrity in Semi-dedicated Hosting
Your semi-dedicated hosting
account will be protected against silent data corruption because all our storage servers work with the state-of-the-art ZFS file system. What makes the latter unique is that it employs checksums, or digital identifiers, so as to verify the integrity of each file. When you upload content to your account, it will be kept on a couple of redundant drives working in a RAID i.e. the files will be the same across all disks. All of the copies of a specific file will have the same checksum on all hard disks and ZFS will compare the checksums of the copies in real time, so if it registers a mismatch, which will indicate that one of the copies is damaged, it will replace that file with a healthy copy from one of the other disks. Even if there is an unexpected power loss, the data on the servers will not be corrupted and there will not be any need for a time-consuming system check which other file systems perform after some breakdown, 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.
