Data corruption is the accidental modification of a file or the loss of information that often occurs during reading or writing. The reason may be hardware or software failure, and due to this fact, a file can become partially or fully corrupted, so it'll no longer function properly as its bits shall be scrambled or lacking. An image file, for instance, will no longer display an actual image, but a random combination of colors, an archive will be impossible to unpack since its content will be unreadable, and so on. If such a problem appears and it's not identified by the system or by an administrator, the data will be corrupted silently and in case this happens on a drive which is part of a RAID array where the information is synced between different drives, the corrupted file shall be replicated on all of the other drives and the damage will be long term. A number of frequently used file systems either don't feature real-time checks or don't have high quality ones which can detect an issue before the damage is done, so silent data corruption is a rather common matter on internet hosting servers where huge volumes of info are kept.
No Data Corruption & Data Integrity in Shared Hosting
We warrant the integrity of the information uploaded in each shared hosting account which is made on our cloud platform as 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 every single file. We shall store your info on a number of NVMe drives that function in a RAID, so the very same files will be available on several places simultaneously. ZFS checks the digital fingerprint of all of the files on all of the drives in real time and in the event that the checksum of any file is different from what it needs to be, the file system swaps that file with an undamaged copy from a different drive from the RAID. There's no other file system that uses checksums, so it's possible for data to get silently corrupted and the bad file to be reproduced on all drives with time, but since that can never happen on a server running ZFS, you won't have to worry about the integrity of your data.
No Data Corruption & Data Integrity in Semi-dedicated Servers
Your semi-dedicated server account will be resistant to silent data corruption since all our storage servers make use of the advanced 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'll be placed on a couple of redundant drives working in a RAID i.e. the files will be the same on all drives. All copies of a given file will have the same checksum on all drives and ZFS will compare the checksums of the copies right away, and if it identifies a mismatch, which will indicate that one of the copies is damaged, it'll swap that file with a healthy copy from one of the other disks. Even if there's an unforeseen power failure, the data on the servers won't get corrupted and there will not be any need for a time-consuming system check that other file systems perform after some failure, extending the time needed for the server to return online. ZFS is the only file system that can really protect your content from silent data corruption.
