Data corruption is the unintentional change of a file or the loss of information which usually occurs during reading or writing. The reason can be hardware or software failure, and as a consequence, a file can become partially or completely corrupted, so it'll no longer work correctly because its bits will be scrambled or lost. An image file, for instance, will no longer present an accurate image, but a random mix of colors, an archive will be impossible to unpack for the reason that its content will be unreadable, etcetera. In the event that such an issue occurs and it is not noticed by the system or by an administrator, the data will become corrupted silently and in case this happens on a disk drive that's a part of a RAID array where the information is synchronized between different drives, the corrupted file shall be replicated on all the other drives and the damage will become long term. A large number of frequently used file systems either don't offer real-time checks or do not have high quality ones which will detect a problem before the damage is done, so silent data corruption is a rather common problem on web hosting servers where substantial amounts of data are kept.
No Data Corruption & Data Integrity in Cloud Web Hosting
The integrity of the data that you upload to your new cloud web hosting
account shall be guaranteed by the ZFS file system that we use on our cloud platform. The vast majority of internet hosting service providers, including our company, use multiple HDDs to store content and considering that the drives work in a RAID, the exact same information is synchronized between the drives all the time. When a file on a drive is corrupted for whatever reason, yet, it's very likely that it will be duplicated 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 single file. In case a file gets damaged, its checksum won't match what ZFS has as a record for it, so the bad copy will be substituted with a good one from a different hard drive. Due to the fact that this happens instantly, there's no possibility for any of your files to ever be damaged.
No Data Corruption & Data Integrity in Semi-dedicated Servers
You won't experience any silent data corruption issues whatsoever if you buy one of our semi-dedicated server
plans due to the fact that the ZFS file system that we take advantage of on our cloud hosting platform uses checksums in order to make sure that all files are undamaged all the time. A checksum is a unique digital fingerprint that is assigned to each and every file kept on a server. Because we store all content on a number of drives at the same time, the same file uses the same checksum on all of 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 right away, avoiding any possibility of the bad copy to be synchronized on the other hard drives. ZFS is the only file system you can find that uses checksums, which makes it much more reliable than other file systems which are not able to identify silent data corruption and duplicate bad files across hard drives.
