Data corruption is the unintended change of a file or the losing of info which usually occurs during reading or writing. The reason could be hardware or software fail, and for that reason, a file could become partially or fully corrupted, so it will no longer function properly as its bits will be scrambled or lost. An image file, for example, will no longer present an actual image, but a random combination of colors, an archive will be impossible to unpack because its content will be unreadable, and so on. When this kind of an issue appears and it isn't identified by the system or by an admin, the data will become corrupted silently and when this happens on a disk drive that's a part of a RAID array where the information is synced between different drives, the corrupted file shall be replicated on all the other drives and the damage will be long term. Many popular file systems either don't have real-time checks or do not have high quality ones that can detect a problem before the damage is done, so silent data corruption is a very common matter on internet hosting servers where large volumes of information are stored.
No Data Corruption & Data Integrity in Shared Hosting
In case you host your Internet sites in a shared hosting account from our company, you don't need to worry about your data ever getting corrupted. We can ensure that since our cloud hosting platform works with the amazing ZFS file system. The aforementioned is the only file system that uses checksums, or unique digital fingerprints, for every single file. All of the information that you upload will be saved in a RAID i.e. simultaneously on a number of NVMes. Many file systems synchronize the files between the different drives using such a setup, but there is no real guarantee that a file will not get corrupted. This could happen throughout the writing process on any drive and after that a damaged copy may be copied on all other drives. What makes the difference on our platform is that ZFS compares the checksums of all files on all drives instantly and in the event that a corrupted file is identified, it's replaced with a good copy with the correct checksum from some other drive. That way, your information will stay undamaged no matter what, even if an entire drive fails.
No Data Corruption & Data Integrity in Semi-dedicated Servers
You will not need to deal with any kind of silent data corruption issues should you purchase one of our semi-dedicated server solutions since the ZFS file system that we employ on our cloud hosting platform uses checksums in order to guarantee that all files are intact all of the time. A checksum is a unique digital fingerprint that is assigned to each and every file stored on a server. Because we store all content on multiple drives at the same time, 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 in real time. In case 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 without delay, avoiding any probability of the corrupted copy to be synchronized on the rest of the drives. ZFS is the sole file system on the market which uses checksums, which makes it much more reliable than other file systems which cannot identify silent data corruption and copy bad files across hard drives.
