Data corruption is the unintentional change of a file or the loss of info that often occurs during reading or writing. The reason can be hardware or software failure, and for that reason, a file could become partially or completely corrupted, so it will no longer work correctly as its bits will be scrambled or lost. An image file, for example, will no longer show a real image, but a random mix of colors, an archive will be impossible to unpack since its content will be unreadable, etc. When this kind of an issue occurs and it is not recognized by the system or by an administrator, the data will be corrupted silently and when this happens on a drive which is a part of a RAID array where the data is synced between various drives, the corrupted file will be duplicated on all of the other drives and the harm will be permanent. Many widely used file systems either do not feature real-time checks or do not have good ones which can detect an issue before the damage is done, so silent data corruption is a common problem on internet hosting servers where huge volumes of info are stored.

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 employ on our cloud platform. Most of the internet hosting suppliers, including our firm, use multiple hard disks to store content and considering that the drives work in a RAID, identical data is synchronized between the drives at all times. If a file on a drive is corrupted for some reason, however, it is likely that it will be copied on the other drives because alternative file systems don't feature special checks for this. In contrast to them, ZFS applies a digital fingerprint, or a checksum, for every single file. In case 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 another disk drive. Since this happens in real time, there's no risk for any of your files to ever be corrupted.

No Data Corruption & Data Integrity in Semi-dedicated Hosting

You will not have to deal with any kind of silent data corruption issues whatsoever if you acquire one of our semi-dedicated hosting plans as the ZFS file system that we work with on our cloud hosting platform uses checksums to guarantee that all files are intact all the time. A checksum is a unique digital fingerprint which is assigned to each and every file kept on a server. Since we store all content on a number of drives at the same time, the same file uses the same checksum on all the drives and what ZFS does is that it compares the checksums between the different drives right away. If it detects that a file is corrupted and its checksum is different from what it should be, it replaces that file with a healthy copy without delay, avoiding any chance of the bad copy to be synchronized on the remaining drives. ZFS is the only file system you can find which uses checksums, which makes it much more reliable than other file systems which are not able to detect silent data corruption and copy bad files across drives.
