Data corruption is the unintentional transformation of a file or the losing of information that often occurs during reading or writing. The reason may be hardware or software fail, and due to this fact, a file can become partially or fully corrupted, so it'll no longer work as it should because its bits will be scrambled or lacking. An image file, for instance, will no longer show an accurate image, but a random combination of colors, an archive will be impossible to unpack as its content will be unreadable, and so on. In case such an issue appears and it's not found by the system or by an administrator, the data will be corrupted silently and if this happens on a drive that's part of a RAID array where the data is synced between various different drives, the corrupted file will be copied on all of the other drives and the harm will be long term. Numerous widely used file systems either do not feature real-time checks or do not have high quality ones that will detect an issue before the damage is done, so silent data corruption is a rather common problem on hosting servers where huge amounts of data are kept.
No Data Corruption & Data Integrity in Cloud Website Hosting
The integrity of the data that you upload to your new cloud website hosting
account will be ensured by the ZFS file system which we make use of on our cloud platform. Most internet hosting suppliers, including our company, use multiple hard disk drives to store content and considering that the drives work in a RAID, identical information is synchronized between the drives at all times. When a file on a drive becomes corrupted for whatever reason, yet, it's more than likely that it will be reproduced on the other drives since alternative file systems don't include special checks for this. Unlike them, ZFS applies 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 damaged copy shall be replaced with a good one from another disk drive. Since this happens instantly, there is no risk for any of your files to ever be corrupted.
No Data Corruption & Data Integrity in Semi-dedicated Hosting
Your semi-dedicated hosting
account will be protected against silent data corruption because all of our storage servers make use of the innovative ZFS file system. What makes the latter unique is that it uses checksums, or digital identifiers, so as to verify the integrity of every single file. When you upload content to your account, it will be stored on several redundant drives being employed in a RAID i.e. the files will be the same on all disks. All copies of a given file will have the same checksum on all hard drives and ZFS will compare the checksums of the copies quickly, so if it identifies a mismatch, which would indicate that one of the copies is corrupted, it will substitute that file with a good copy from one of the other drives. Even if there is an unforeseen power failure, the data on the servers won't be corrupted and there won't be any need for a time-consuming system check which other file systems perform after some failure, lengthening the time needed for the server to return online. ZFS is the only file system which can really protect your content from silent data corruption.
