Data corruption is the unintended transformation of a file or the loss of info that usually occurs during reading or writing. The reason could be hardware or software malfunction, and due to this fact, a file could become partially or fully corrupted, so it'll no longer function correctly since its bits shall be scrambled or lost. An image file, for example, will no longer display a true image, but a random mix of colors, an archive will be impossible to unpack as its content will be unreadable, etc. In case this kind of a problem appears and it isn't found by the system or by an administrator, the data will get corrupted silently and when this happens on a disk drive that is part of a RAID array where the data is synchronized between various drives, the corrupted file shall be replicated on all the other drives and the harm will become permanent. Numerous popular file systems either do not offer real-time checks or don't 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 substantial amounts of data are kept.
No Data Corruption & Data Integrity in Shared Web Hosting
We guarantee the integrity of the data uploaded in each shared web hosting
account that is generated on our cloud platform as we work with the advanced ZFS file system. The aforementioned is the only one that was designed to prevent silent data corruption thanks to a unique checksum for every single file. We shall store your data on multiple SSD drives which function in a RAID, so the very same files will be available on several places at once. ZFS checks the digital fingerprint of all the files on all drives in real time and in the event that the checksum of any file is different from what it should be, the file system swaps that file with a healthy version from another drive in the RAID. There's no other file system which uses checksums, so it's easy for data to become silently damaged and the bad file to be duplicated on all drives over time, but since this 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 will not have to deal with any kind of silent data corruption issues should you get one of our semi-dedicated hosting
plans because the ZFS file system that we employ on our cloud hosting platform uses checksums to guarantee that all of your files are undamaged at all times. A checksum is a unique digital fingerprint that is allotted to each and every file stored on a server. Since we store all content on multiple drives at the same time, the same file has the same checksum on all drives and what ZFS does is that it compares the checksums between the different drives right away. When it detects that a file is corrupted and its checksum is different from what it should be, it replaces that file with a healthy copy right away, avoiding any probability of the corrupted copy to be synchronized on the rest of the hard disks. ZFS is the sole file system available on the market that uses checksums, which makes it much more reliable than other file systems which cannot detect silent data corruption and duplicate bad files across drives.
