Data corruption is the accidental transformation of a file or the loss of info that usually occurs during reading or writing. The reason may be hardware or software malfunction, and as a consequence, a file may become partially or fully corrupted, so it will no longer function correctly since its bits shall be scrambled or lost. An image file, for instance, will no longer present an authentic image, but a random mix of colors, an archive will be impossible to unpack for the reason that its content will be unreadable, and so on. In case this kind of a problem occurs and it isn't noticed by the system or by an administrator, the data will get corrupted silently and in case this happens on a drive that is part of a RAID array where the information is synchronized between various drives, the corrupted file shall be duplicated on all the other drives and the damage will become permanent. A number of frequently used file systems either don't offer real-time checks or don't have good ones that can detect a problem before the damage is done, so silent data corruption is a common issue on hosting servers where large amounts of information are kept.
No Data Corruption & Data Integrity in Hosting
In case you host your Internet sites in a hosting account with our company, you will not have to worry about your data ever getting corrupted. We can ensure that because our cloud hosting platform works with the revolutionary ZFS file system. The latter is the only file system which uses checksums, or unique digital fingerprints, for every single file. All the data that you upload will be kept in a RAID i.e. simultaneously on many SSDs. All file systems synchronize the files between the separate drives with this kind of a setup, but there is no real warranty that a file won't get corrupted. This may occur during the writing process on each drive and after that a damaged copy may be copied on the other drives. What makes the difference on our platform is the fact that ZFS compares the checksums of all files on all the drives in real time and when a corrupted file is located, it is replaced with a good copy with the correct checksum from some other drive. This way, your data will stay unharmed no matter what, even if an entire drive fails.
