Data corruption is the unintentional change of a file or the losing of info which usually occurs during reading or writing. The reason could be hardware or software failure, and consequently, a file may become partially or entirely corrupted, so it will no longer function properly as its bits shall be scrambled or lacking. An image file, for example, will no longer show a true image, but a random mix of colors, an archive will be impossible to unpack for the reason that its content will be unreadable, etc. When this kind of a problem occurs and it is not found by the system or by an admin, the data will become corrupted silently and in case this happens on a drive that's a part of a RAID array where the data is synchronized between various drives, the corrupted file shall be copied on all the other drives and the damage will become permanent. A number of widely used file systems either don't have real-time checks or don't have high quality ones that will detect an issue before the damage is done, so silent data corruption is a very common problem on internet hosting servers where huge volumes of information are kept.
No Data Corruption & Data Integrity in Website Hosting
The integrity of the data which you upload to your new website hosting
account will be guaranteed by the ZFS file system that we take advantage of on our cloud platform. Most of the web hosting service providers, including our firm, use multiple hard disk drives to keep content and since the drives work in a RAID, identical information is synchronized between the drives all the time. When a file on a drive is damaged for some reason, however, it's more than likely that it will be copied on the other drives because alternative file systems don't offer special checks for that. In contrast to them, ZFS uses a digital fingerprint, or a checksum, for every file. In the event that a file gets damaged, its checksum will not match what ZFS has as a record for it, therefore the bad copy will be replaced with a good one from a different hard drive. Due to the fact that this happens in real time, there is no possibility for any of your files to ever be damaged.
No Data Corruption & Data Integrity in Semi-dedicated Hosting
You will not encounter any kind of silent data corruption issues should you acquire one of our semi-dedicated hosting
packages because the ZFS file system that we employ on our cloud hosting platform uses checksums in order to make sure that all of the files are intact at all times. A checksum is a unique digital fingerprint which is given to each and every file stored on a server. As we store all content on multiple drives simultaneously, the same file has the same checksum on all drives and what ZFS does is that it compares the checksums between the different drives right away. In case 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 without delay, avoiding any chance of the bad copy to be synchronized on the rest of the drives. ZFS is the sole file system out there which uses checksums, which makes it much more dependable than other file systems which cannot detect silent data corruption and copy bad files across drives.
