Data corruption is the unintentional modification of a file or the loss of info which usually occurs during reading or writing. The reason may be hardware or software failure, and for that reason, a file can become partially or entirely corrupted, so it'll no longer function as it should since its bits will be scrambled or lacking. An image file, for example, will no longer present an actual image, but a random mix of colors, an archive will be impossible to unpack since its content will be unreadable, and so on. In the event that such a problem appears and it is not identified by the system or by an admin, the data will be corrupted silently and in case this happens on a drive which is a part of a RAID array where the information is synchronized between various drives, the corrupted file shall be reproduced on all the other drives and the damage will be long term. Numerous frequently used file systems either do not have real-time checks or do not have good ones which can detect an issue before the damage is done, so silent data corruption is a common problem on internet hosting servers where large amounts of information are stored.

No Data Corruption & Data Integrity in Shared Hosting

If you host your Internet sites in a shared hosting account from our firm, you do not need to worry about your data ever getting corrupted. We can guarantee that since our cloud hosting platform employs the leading-edge ZFS file system. The latter is the only file system which works with checksums, or unique digital fingerprints, for each file. Any kind of data that you upload will be stored in a RAID i.e. simultaneously on a number of SSDs. All of the file systems synchronize the files between the separate drives with such a setup, but there is no real warranty that a file will not be corrupted. This may occur at the time of the writing process on each drive and then a damaged copy can be copied on the rest of the drives. What makes the difference on our platform is that ZFS analyzes the checksums of all files on all drives right away and in case a corrupted file is found, it is substituted with a good copy with the correct checksum from another drive. In this way, your information will remain intact no matter what, even if an entire drive fails.

No Data Corruption & Data Integrity in Semi-dedicated Servers

We have avoided any risk of files getting corrupted silently due to the fact that the servers where your semi-dedicated server account will be created take advantage of a powerful file system named ZFS. Its main advantage over alternative file systems is that it uses a unique checksum for each file - a digital fingerprint which is checked in real time. Since we keep all content on a number of SSD drives, ZFS checks whether the fingerprint of a file on one drive matches the one on the other drives and the one it has saved. When there is a mismatch, the corrupted copy is replaced with a good one from one of the other drives and considering that it happens instantly, there's no chance that a damaged copy could remain on our hosting servers or that it can be copied to the other drives in the RAID. None of the other file systems include this type of checks and furthermore, even during a file system check after an unexpected power loss, none of them can detect silently corrupted files. In contrast, ZFS won't crash after an electrical power failure and the regular checksum monitoring makes a time-consuming file system check unnecessary.
