Data corruption is the accidental transformation of a file or the losing of info that usually occurs during reading or writing. The reason may be hardware or software malfunction, and for that reason, a file could become partially or fully corrupted, so it will no longer function properly since its bits will be scrambled or missing. An image file, for instance, will no longer present an authentic image, but a random mix of colors, an archive will be impossible to unpack for the reason that its content will be unreadable, etc. In case this kind of a problem occurs and it's not identified by the system or by an admin, the data will be corrupted silently and in case this happens on a disk drive that is a part of a RAID array where the data is synced between different drives, the corrupted file shall be duplicated on all the other drives and the damage will become permanent. A large number of widely used file systems either do not feature real-time checks or don't have good ones that will detect an issue before the damage is done, so silent data corruption is a rather common issue on internet hosting servers where large volumes of information are stored.
No Data Corruption & Data Integrity in Shared Hosting
We guarantee the integrity of the data uploaded in every single shared hosting
account which is generated on our cloud platform due to the fact that we work with the advanced ZFS file system. The latter is the only one that was designed to prevent silent data corruption via a unique checksum for every single file. We shall store your data on multiple SSD drives that operate in a RAID, so exactly the same files will be present on several places concurrently. ZFS checks the digital fingerprint of all the files on all the drives in real time and in case the checksum of any file differs from what it has to be, the file system swaps that file with a healthy version from another drive inside the RAID. No other file system uses checksums, so it is possible for data to be silently corrupted and the bad file to be reproduced on all drives over time, but since that can never happen on a server running ZFS, you will not have to concern yourself with the integrity of your data.
No Data Corruption & Data Integrity in Semi-dedicated Hosting
You won't have to deal with any silent data corruption issues whatsoever should you acquire one of our semi-dedicated hosting
plans because the ZFS file system that we take advantage of on our cloud hosting platform uses checksums to ensure that all of your files are intact at all times. A checksum is a unique digital fingerprint which is allotted to each and every file kept on a server. Since we store all content on a number of drives simultaneously, the same file uses the same checksum on all of the drives and what ZFS does is that it compares the checksums between the different drives right away. In the event that it detects that a file is corrupted and its checksum is different from what it has to be, it replaces that file with a healthy copy right away, avoiding any chance of the damaged copy to be synchronized on the other hard disks. ZFS is the only file system available on the market which uses checksums, which makes it far superior to other file systems that are unable to identify silent data corruption and duplicate bad files across drives.
