Data corruption is the unintended modification of a file or the loss of info which often occurs during reading or writing. The reason can be hardware or software fail, and consequently, a file could become partially or completely corrupted, so it'll no longer work correctly as its bits shall be scrambled or lost. An image file, for instance, will no longer present a real image, but a random combination of colors, an archive will be impossible to unpack because its content will be unreadable, and so on. If such an issue appears and it is not found by the system or by an admin, the data will get corrupted silently and if this happens on a drive that's part of a RAID array where the information is synced between different drives, the corrupted file will be duplicated on all other drives and the harm will be permanent. Numerous commonly used file systems either do not have real-time checks or do not have good ones which can detect a problem before the damage is done, so silent data corruption is a very common matter on web hosting servers where substantial volumes of info are stored.
No Data Corruption & Data Integrity in Cloud Hosting
The integrity of the data that you upload to your new cloud hosting
account will be guaranteed by the ZFS file system which we employ on our cloud platform. The vast majority of internet hosting providers, like our company, use multiple hard disks to store content and considering that the drives work in a RAID, identical info is synchronized between the drives all of the time. In case a file on a drive gets damaged for some reason, yet, it's very likely that it will be reproduced on the other drives because other file systems do not feature special checks for that. In contrast to them, ZFS applies a digital fingerprint, or a checksum, for each and every file. In case a file gets damaged, its checksum won't match what ZFS has as a record for it, which means that the bad copy will be substituted with a good one from another disk drive. As this happens instantly, there is no risk for any of your files to ever be corrupted.
No Data Corruption & Data Integrity in Semi-dedicated Servers
In case you get one of our semi-dedicated server
plans, you will not have to worry about silent file corruption because we use ZFS - an advanced file system which checks all of the files in real time. Every time you upload a file to your account, ZFS will assign a unique digital fingerprint to it - the so-called checksum. The file will be synced between a couple of SSD drives for redundancy, so if one drive fails, the other ones will take over. ZFS compares the checksum of all the copies on the different drives and if it detects a damaged copy, it replaces it with a healthy one from another drive. This is done in real time, so there will be no threat for any part of your content at any moment. In comparison, alternative file systems perform checks after a system failure, but since they don't use anything similar to the checksums which ZFS uses, they can't detect silently corrupted files, so a corrupted copy may be replicated on the remaining disks as well and you can lose precious information. As this isn't the case with ZFS, we are able to guarantee the integrity of each file you upload no matter what.
