Data corruption is the unintentional transformation of a file or the loss of info which often occurs during reading or writing. The reason could be hardware or software failure, and as a result, a file can become partially or completely corrupted, so it will no longer function correctly since 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 as its content will be unreadable, etcetera. In case such an issue appears and it isn't identified by the system or by an admin, the data will get corrupted silently and if this happens on a drive which is a part of a RAID array where the data is synchronized between various different drives, the corrupted file will be copied on all of the other drives and the damage will be permanent. A number of widely used file systems either do not feature real-time checks or do not have good ones which can detect a problem before the damage is done, so silent data corruption is a rather common issue on web hosting servers where large amounts of information are stored.
No Data Corruption & Data Integrity in Shared Hosting
The integrity of the data which you upload to your new shared hosting account will be ensured by the ZFS file system which we take advantage of on our cloud platform. The majority of hosting providers, like our firm, use multiple hard disks to store content and because the drives work in a RAID, the exact same data is synchronized between the drives all the time. When a file on a drive gets corrupted for some reason, however, it is more than likely that it will be reproduced on the other drives since alternative file systems do not have special checks for this. In contrast to them, ZFS employs a digital fingerprint, or a checksum, for each and every file. In the event that a file gets corrupted, its checksum won't match what ZFS has as a record for it, so the bad copy will be swapped with a good one from a different hard drive. Since this happens immediately, there's no possibility for any of your files to ever be corrupted.
