Data corruption is the unintended transformation of a file or the loss of information that usually occurs during reading or writing. The reason may be hardware or software fail, and because of this, a file can become partially or entirely corrupted, so it will no longer work properly because its bits shall be scrambled or lacking. An image file, for example, will no longer display an actual 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. In the event that such a problem appears and it isn't identified by the system or by an admin, the data will be corrupted silently and when this happens on a disk drive which is part of a RAID array where the info is synced between various drives, the corrupted file will be copied on all of the other drives and the damage will be long term. Many frequently used file systems either don't feature real-time checks or do not have good ones that will detect an issue before the damage is done, so silent data corruption is a common problem on internet hosting servers where large amounts of data are kept.
No Data Corruption & Data Integrity in Cloud Hosting
We guarantee the integrity of the data uploaded in each cloud hosting account that is created on our cloud platform since we employ the advanced ZFS file system. The aforementioned is the only one which was designed to prevent silent data corruption via a unique checksum for each file. We shall store your info on a number of SSD drives which work in a RAID, so the same files will be available on several places simultaneously. ZFS checks the digital fingerprint of all of the files on all drives in real time and in the event that the checksum of any file is different from what it has to be, the file system replaces that file with a healthy version from a different drive within the RAID. There's no other file system which uses checksums, so it's possible for data to get silently damaged and the bad file to be replicated on all drives over time, but since that can never happen on a server running ZFS, you won't have to concern yourself with the integrity of your info.
No Data Corruption & Data Integrity in Semi-dedicated Hosting
Your semi-dedicated hosting account will be protected against silent data corruption as all our storage servers make use of the reliable ZFS file system. What makes the aforementioned unique is that it employs checksums, or digital identifiers, so as to ensure the integrity of each and every file. When you upload content to your account, it will be kept on a couple of redundant drives operating in a RAID i.e. the files shall be the same on all disks. All the copies of a given file will feature the same checksum on all hard drives and ZFS will compare the checksums of the copies right away, and if it finds a mismatch, which will indicate that one of the copies is corrupted, it'll replace that file with a healthy copy from one of the other drives. Even if there's an unexpected blackout, 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 breakdown, prolonging the time needed for the server to get back online. ZFS is the only file system that can truly protect your content from silent data corruption.
