Data corruption is the unintentional transformation of a file or the losing of info which often occurs during reading or writing. The reason can be hardware or software malfunction, and consequently, a file could become partially or completely 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 display a true image, but a random combination of colors, an archive will be impossible to unpack for the reason that its content will be unreadable, etcetera. In case this kind of an issue occurs and it is not noticed by the system or by an administrator, the data will get corrupted silently and if this happens on a disk drive that is a part of a RAID array where the data is synchronized between various different drives, the corrupted file will be reproduced on all other drives and the harm will be long term. A large number of frequently used file systems either do not have real-time checks or do not have high quality ones that will detect an issue before the damage is done, so silent data corruption is a very common problem on hosting servers where substantial volumes of data are stored.

No Data Corruption & Data Integrity in Shared Hosting

In case you host your websites in a shared hosting account with our company, you will not have to worry about your data ever getting corrupted. We can ensure that as our cloud hosting platform uses the state-of-the-art ZFS file system. The latter is the only file system that works with checksums, or unique digital fingerprints, for every single file. All info that you upload will be stored in a RAID i.e. simultaneously on a number of SSDs. Many file systems synchronize the files between the separate drives with this kind of a setup, but there is no real warranty that a file will not get corrupted. This could happen at the time of the writing process on any drive and then a damaged copy may be copied on the rest of the drives. What makes the difference on our platform is that ZFS examines the checksums of all files on all drives live and if a corrupted file is found, it is replaced with a good copy with the correct checksum from another drive. In this way, your data will continue to be unharmed no matter what, even if a whole drive fails.

No Data Corruption & Data Integrity in Semi-dedicated Hosting

We've avoided any possibility of files getting corrupted silently due to the fact that the servers where your semi-dedicated hosting account will be created work with a powerful file system named ZFS. Its basic advantage over various other file systems is that it uses a unique checksum for each and every file - a digital fingerprint which is checked in real time. As we keep all content on numerous SSD drives, ZFS checks if the fingerprint of a file on one drive matches the one on the other drives and the one it has saved. If there is a mismatch, the bad copy is replaced with a good one from one of the other drives and since this happens in real time, there's no chance that a damaged copy can remain on our web hosting servers or that it could be duplicated to the other drives in the RAID. None of the other file systems employ this kind of checks and furthermore, even during a file system check after an unexpected blackout, none of them will find silently corrupted files. In contrast, ZFS doesn't crash after a blackout and the continual checksum monitoring makes a time-consuming file system check obsolete.
