Data corruption is the unintended change of a file or the losing of information which often occurs during reading or writing. The reason can be hardware or software failure, and for that reason, a file can become partially or completely corrupted, so it will no longer function properly because its bits will be scrambled or missing. 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 since its content will be unreadable, etcetera. If this kind of an issue occurs and it isn't noticed by the system or by an admin, the data will get corrupted silently and if this happens on a disk drive that's part of a RAID array where the info is synced between different drives, the corrupted file will be duplicated on all the other drives and the damage will become permanent. Many popular file systems either don't offer real-time checks or do not have high quality ones that will detect a problem before the damage is done, so silent data corruption is a common issue on web hosting servers where huge volumes of data are kept.

No Data Corruption & Data Integrity in Cloud Hosting

In case you host your sites in a cloud hosting account with our company, you don't need to worry about any of your data ever getting damaged. We can ensure that since our cloud hosting platform works with the amazing ZFS file system. The aforementioned is the only file system which uses checksums, or unique digital fingerprints, for each file. All the info that you upload will be kept in a RAID i.e. simultaneously on numerous NVMe drives. A lot of file systems synchronize the files between the different drives using such a setup, but there is no real guarantee that a file won't get corrupted. This may occur during the writing process on each drive and then a corrupted copy can be copied on the other drives. What makes the difference on our platform is that ZFS compares the checksums of all files on all drives in real time and in case a corrupted file is discovered, it's substituted with a good copy with the correct checksum from another drive. By doing this, your info will stay undamaged no matter what, even if an entire drive fails.

No Data Corruption & Data Integrity in Semi-dedicated Servers

You won't encounter any kind of silent data corruption issues in case you buy one of our semi-dedicated server packages since the ZFS file system that we employ on our cloud hosting platform uses checksums to guarantee that all files are undamaged all of the time. A checksum is a unique digital fingerprint which is assigned to each and every file stored on a server. Since we store all content on a number of drives at the same time, the same file uses the same checksum on all drives and what ZFS does is that it compares the checksums between the different drives in real time. In case 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 drives. ZFS is the only file system available on the market that uses checksums, which makes it far superior to other file systems which cannot identify silent data corruption and duplicate bad files across drives.
