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 failure, and as a consequence, a file can become partially or entirely corrupted, so it'll no longer work as it should as its bits will be scrambled or lacking. An image file, for instance, will no longer present a true image, but a random combination of colors, an archive will be impossible to unpack for the reason that its content will be unreadable, and so on. When such a problem occurs and it is not found by the system or by an administrator, the data will get corrupted silently and in case this happens on a drive that is part of a RAID array where the information is synced between various drives, the corrupted file will be copied on all other drives and the harm will become permanent. Many commonly 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 rather common matter on hosting servers where huge volumes of data are stored.
No Data Corruption & Data Integrity in Cloud Web Hosting
The integrity of the data which you upload to your new cloud web hosting
account will be guaranteed by the ZFS file system that we take advantage of on our cloud platform. The vast majority of internet hosting providers, like our firm, use multiple HDDs to keep content and because the drives work in a RAID, exactly the same data is synchronized between the drives all of the time. If a file on a drive is damaged for some reason, yet, it's very likely that it will be copied on the other drives as alternative file systems do not include special checks for that. Unlike them, ZFS works with a digital fingerprint, or a checksum, for every single file. If a file gets corrupted, its checksum will not match what ZFS has as a record for it, therefore the damaged copy will be substituted with a good one from a different disk drive. Since this happens right away, there's no possibility for any of your files to ever be corrupted.
No Data Corruption & Data Integrity in Semi-dedicated Hosting
In case you go for one of our semi-dedicated hosting
plans, you will not have to be concerned about silent data corruption as we use ZFS - a high level file system that keeps track of all the files in real time. Each time you upload a file to your hosting account, ZFS will assign a unique digital fingerprint to it - the so-called checksum. The file will be synchronized between several 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 when it detects a damaged copy, it replaces it with a healthy one from another drive. This is done immediately, so there will be no threat for any part of your content at any time. In contrast, all of the other file systems execute checks only after a system malfunction, but since they don't use anything similar to the checksums which ZFS uses, they can't detect silently corrupted files, so a bad copy could be replicated on the rest of the drives as well and you can lose important information. Since this is not the case with ZFS, we can guarantee the integrity of each and every file you upload no matter what.
