Data corruption is the accidental transformation of a file or the loss of info that often occurs during reading or writing. The reason may be hardware or software failure, and because of this, a file could become partially or entirely corrupted, so it'll no longer function as it should because its bits will be scrambled or lacking. An image file, for instance, will no longer show an actual image, but a random mix of colors, an archive will be impossible to unpack for the reason that its content will be unreadable, and so on. In the event that such a problem occurs and it is not noticed by the system or by an administrator, the data will be corrupted silently and in case this happens on a disk drive that's a part of a RAID array where the info is synced between different drives, the corrupted file shall be reproduced on all other drives and the harm will be long term. Numerous frequently used file systems either don't offer real-time checks or don't have good ones which will detect an issue before the damage is done, so silent data corruption is a rather common matter on web hosting servers where huge volumes of info are kept.
No Data Corruption & Data Integrity in Shared Web Hosting
The integrity of the data that you upload to your new shared web hosting account will be ensured by the ZFS file system which we take advantage of on our cloud platform. Most of the internet hosting suppliers, like our company, use multiple hard disks to store 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 becomes corrupted for reasons unknown, yet, it's likely that it will be copied on the other drives because other file systems do not offer special checks for that. In contrast to them, ZFS uses a digital fingerprint, or a checksum, for every file. In case a file gets corrupted, its checksum will not match what ZFS has as a record for it, therefore the damaged copy shall be replaced with a good one from another hard drive. Because 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
Your semi-dedicated server account will be shielded from silent data corruption because all our storage servers use the effective ZFS file system. What makes the aforementioned unique is that it uses checksums, or digital identifiers, so as to ensure the integrity of each and every file. When you upload content to your account, it'll be placed on a couple of redundant drives working in a RAID i.e. the files shall be the same on all disks. All the copies of a specific file will have the same checksum on all hard drives and ZFS will compare the checksums of the duplicates right away, and if it detects a mismatch, that would indicate that one of the copies is corrupted, it'll substitute that file with a good copy from one of the other disks. Even if there is a sudden power loss, the data on the servers will not get corrupted and there won't be any need for a time-consuming system check that other file systems perform after some breakdown, prolonging the time needed for the server to return online. ZFS is the sole file system that can truly protect your content from silent data corruption.
