The process of files getting damaged because of some hardware or software failure is known as data corruption and this is among the main problems that web hosting companies face as the larger a hard disk is and the more info is stored on it, the much more likely it is for data to get corrupted. You'll find several fail-safes, but often the data gets damaged silently, so neither the file system, nor the administrators detect a thing. Because of this, a bad file will be treated as a good one and if the hard disk is part of a RAID, that particular file will be copied on all other drives. Theoretically, this is done for redundancy, but in reality the damage will get even worse. Once a file gets corrupted, it will be partly or completely unreadable, which means that a text file will not be readable, an image file will display a random blend of colors in case it opens at all and an archive will be impossible to unpack, and you risk losing your site content. Although the most frequently used server file systems have various checks, they frequently fail to identify a problem early enough or require a long amount of time to check all of the files and the web server will not be operational for the time being.
No Data Corruption & Data Integrity in Shared Hosting
The integrity of the data which you upload to your new shared hosting account shall be guaranteed by the ZFS file system that we take advantage of on our cloud platform. The majority of web hosting providers, like our firm, use multiple hard drives to keep content and considering that the drives work in a RAID, identical information is synchronized between the drives all the time. If a file on a drive gets corrupted for reasons unknown, however, it is very likely that it will be copied on the other drives because alternative file systems do not have special checks for this. In contrast to them, ZFS uses a digital fingerprint, or a checksum, for every single file. In the event that a file gets corrupted, its checksum will not match what ZFS has as a record for it, and the bad copy will be replaced 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 Servers
You won't need to deal with any silent data corruption issues if you obtain one of our semi-dedicated server solutions due to the fact that the ZFS file system that we employ on our cloud hosting platform uses checksums in order to guarantee that all of your files are intact at all times. A checksum is a unique digital fingerprint that is allotted to each and every file stored on a server. Because we store all content on a number of drives at the same time, the same file has the same checksum on all the drives and what ZFS does is that it compares the checksums between the different drives right away. In the event that it detects that a file is corrupted and its checksum is different from what it has to be, it replaces that file with a healthy copy right away, avoiding any chance of the corrupted copy to be synchronized on the remaining drives. ZFS is the sole file system you can get which uses checksums, which makes it much more reliable than other file systems which are unable to identify silent data corruption and duplicate bad files across drives.
