Data corruption is the unintended change of a file or the losing of information which usually occurs during reading or writing. The reason can be hardware or software fail, and for that reason, a file can become partially or fully corrupted, so it'll no longer work properly as its bits will be scrambled or lost. An image file, for instance, will no longer present an authentic 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 such an issue 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 which is part of a RAID array where the information is synchronized between various drives, the corrupted file will be copied on all the other drives and the damage will be permanent. A large number of frequently used file systems either don't feature real-time checks or do not have high quality ones which will detect a problem before the damage is done, so silent data corruption is a common matter on hosting servers where large amounts 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 firm, you will not have to worry about your data ever getting corrupted. We can ensure that because our cloud hosting platform employs the reliable ZFS file system. The latter is the only file system which works with checksums, or unique digital fingerprints, for every single file. Any kind of information that you upload will be saved in a RAID i.e. simultaneously on a large number of SSDs. Many file systems synchronize the files between the different drives using this type of a setup, but there's no real guarantee that a file will not get corrupted. This can occur throughout the writing process on each drive and afterwards a corrupted copy can be copied on the other drives. What is different on our platform is that ZFS compares the checksums of all files on all of the drives instantly and when a corrupted file is identified, it's substituted with a good copy with the correct checksum from some other drive. By doing this, your info will stay 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 should you acquire one of our semi-dedicated hosting
packages because the ZFS file system that we employ on our cloud hosting platform uses checksums in order to guarantee that all of your files are undamaged all the time. A checksum is a unique digital fingerprint which is assigned to each and every file saved on a server. As we store all content on a number of drives simultaneously, 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. In the event that 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 possibility of the bad copy to be synchronized on the rest of the drives. ZFS is the only file system available on the market which uses checksums, which makes it far superior to other file systems which cannot identify silent data corruption and duplicate bad files across hard drives.
