Data corruption is the unintended change of a file or the losing of info which often occurs during reading or writing. The reason can be hardware or software failure, and as a consequence, a file could become partially or completely corrupted, so it will no longer function correctly since its bits will be scrambled or lacking. An image file, for instance, will no longer show a true image, but a random mix of colors, an archive will be impossible to unpack for the reason that its content will be unreadable, etcetera. If such a problem appears and it isn't recognized by the system or by an admin, the data will be corrupted silently and if this happens on a disk drive that is a part of a RAID array where the data is synced between various drives, the corrupted file will be replicated on all the other drives and the harm will become permanent. A large number of commonly used file systems either don't offer real-time checks or do not have good ones which will detect an issue before the damage is done, so silent data corruption is a rather common matter on hosting servers where huge volumes of info are kept.
No Data Corruption & Data Integrity in Shared Hosting
If you host your sites in a shared hosting
account with our firm, you won't have to worry about your data ever getting corrupted. We can guarantee that because our cloud hosting platform employs the state-of-the-art ZFS file system. The aforementioned is the only file system that uses checksums, or unique digital fingerprints, for every single file. Any information that you upload will be stored in a RAID i.e. simultaneously on many different SSDs. Many file systems synchronize the files between the separate drives with this kind of a setup, but there is no real guarantee that a file won't be corrupted. This could happen at the time of the writing process on each drive and afterwards a corrupted copy may be copied on the rest of the drives. What is different on our platform is the fact that ZFS compares the checksums of all files on all drives instantly and if a corrupted file is located, it's swapped with a good copy with the correct checksum from some other drive. By doing this, your info will stay unharmed no matter what, even if an entire drive fails.
No Data Corruption & Data Integrity in Semi-dedicated Servers
You will not experience any silent data corruption issues if you acquire one of our semi-dedicated server
packages because the ZFS file system that we employ on our cloud hosting platform uses checksums to guarantee that all the files are undamaged all of the time. A checksum is a unique digital fingerprint that is given to each and every file saved 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. If 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 without delay, avoiding any chance of the bad copy to be synchronized on the rest of the hard disks. ZFS is the sole file system you will find that uses checksums, which makes it much more reliable than other file systems which are unable to detect silent data corruption and duplicate bad files across hard drives.
