Data corruption is the unintended change of a file or the loss of information that often occurs during reading or writing. The reason can be hardware or software fail, and because of this, a file could become partially or completely corrupted, so it'll no longer work as it should because its bits will be scrambled or lost. An image file, for example, will no longer present a true image, but a random combination of colors, an archive will be impossible to unpack for the reason that its content will be unreadable, etc. In case this kind of an issue appears and it's not identified by the system or by an administrator, the data will be corrupted silently and when this happens on a disk drive that is part of a RAID array where the info is synced between various drives, the corrupted file will be reproduced on all other drives and the damage will become permanent. Numerous frequently used file systems either do not feature real-time checks or don't have high quality ones that will detect a problem before the damage is done, so silent data corruption is a rather common matter on internet hosting servers where huge amounts of information are kept.
No Data Corruption & Data Integrity in Shared Web Hosting
In case you host your websites in a shared web hosting account with our company, you will not need to worry about any of your data ever getting damaged. We can ensure that due to the fact that our cloud hosting platform employs the leading-edge ZFS file system. The aforementioned is the only file system which works with checksums, or unique digital fingerprints, for each file. Any kind of info that you upload will be saved in a RAID i.e. simultaneously on many different SSDs. All file systems synchronize the files between the different drives with this type of a setup, but there's no real guarantee that a file will not be corrupted. This could occur during the writing process on each drive and after that a damaged copy can be copied on all other drives. What makes the difference on our platform is that ZFS compares the checksums of all files on all the drives right away and if a corrupted file is found, it's substituted with a good copy with the correct checksum from some other drive. That way, your data will remain intact 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 whatsoever in case you purchase one of our semi-dedicated hosting packages since the ZFS file system that we work with on our cloud hosting platform uses checksums to guarantee that all the files are intact all of the time. A checksum is a unique digital fingerprint which is given to each and every file stored on a server. Due to the fact that we store all content on a number of drives at the same time, the same file has the same checksum on all the 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 has to be, it replaces that file with a healthy copy right away, avoiding any probability of the corrupted copy to be synchronized on the other drives. ZFS is the sole file system you can get that uses checksums, which makes it much more reliable than other file systems which are not able to identify silent data corruption and copy bad files across drives.
