Data corruption is the unintentional transformation of a file or the losing of info that often occurs during reading or writing. The reason can be hardware or software failure, and because of this, a file may become partially or entirely corrupted, so it'll no longer work correctly because its bits will be scrambled or lost. An image file, for instance, will no longer present a real image, but a random combination of colors, an archive will be impossible to unpack for the reason that its content will be unreadable, etc. When such a problem appears and it is not noticed by the system or by an administrator, the data will get corrupted silently and when this happens on a drive that's a part of a RAID array where the data is synced between various different drives, the corrupted file will be reproduced on all of the other drives and the harm will become permanent. A large number of widely used file systems either don't feature 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 very common matter on web hosting servers where substantial amounts of information are kept.
No Data Corruption & Data Integrity in Shared Website Hosting
In case you host your Internet sites in a shared website hosting
account from our firm, you won't have to worry about your data ever getting damaged. We can guarantee that as our cloud hosting platform employs the leading-edge ZFS file system. The latter is the only file system that works with checksums, or unique digital fingerprints, for each file. Any kind of info that you upload will be stored in a RAID i.e. simultaneously on a number of SSD drives. All the file systems synchronize the files between the separate drives using this type of a setup, but there is no real warranty that a file won't get corrupted. This can occur at the time of the writing process on each drive and then a bad copy can be copied on the other drives. What makes the difference on our platform is that ZFS compares the checksums of all files on all the drives live and when a corrupted file is located, it is substituted with a good copy with the correct checksum from some other drive. This way, your info will remain undamaged no matter what, even if an entire drive fails.
No Data Corruption & Data Integrity in Semi-dedicated Hosting
You won't have to deal with any kind of silent data corruption issues if you purchase one of our semi-dedicated hosting
packages as the ZFS file system that we work with on our cloud hosting platform uses checksums in order to make sure that all of your files are intact all of the time. A checksum is a unique digital fingerprint which is allotted to each and every file kept on a server. As we store all content on multiple drives simultaneously, the same file uses the same checksum on all drives and what ZFS does is that it compares the checksums between the different drives right away. 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 possibility of the bad copy to be synchronized on the other hard drives. ZFS is the sole file system you can find which uses checksums, which makes it far superior to other file systems that are unable to detect silent data corruption and duplicate bad files across drives.
