Data corruption is the unintended modification of a file or the loss of info which usually occurs during reading or writing. The reason can be hardware or software fail, and as a result, a file can become partially or entirely corrupted, so it'll no longer work correctly because its bits shall be scrambled or missing. An image file, for instance, will no longer display a real image, but a random mix of colors, an archive will be impossible to unpack for the reason that its content will be unreadable, etc. In case this kind of an issue appears 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's a part of a RAID array where the data is synced between various different drives, the corrupted file shall be copied on all of the other drives and the damage will become permanent. Numerous commonly used file systems either do not feature real-time checks or don't have high quality ones that will detect a problem before the damage is done, so silent data corruption is a rather common matter on hosting servers where large volumes of info are kept.

No Data Corruption & Data Integrity in Hosting

If you host your websites in a hosting account from our company, you do not have to worry about any of your data ever getting damaged. We can ensure that due to the fact that our cloud hosting platform employs the advanced ZFS file system. The aforementioned is the only file system which works with checksums, or unique digital fingerprints, for every single file. All of the info that you upload will be kept in a RAID i.e. simultaneously on many SSDs. A lot of file systems synchronize the files between the separate drives with this type of a setup, but there is no real warranty that a file won't be corrupted. This can occur during the writing process on any drive and after that a damaged copy may be copied on the rest of the drives. What makes the difference on our platform is the fact that ZFS examines the checksums of all files on all the drives instantly and in case a corrupted file is found, it is replaced with a good copy with the correct checksum from some other drive. This way, your information will remain undamaged no matter what, even if an entire drive fails.

No Data Corruption & Data Integrity in Semi-dedicated Servers

You will not encounter any silent data corruption issues in case you acquire one of our semi-dedicated server plans as the ZFS file system that we use on our cloud hosting platform uses checksums to ensure that all of your files are undamaged at all times. A checksum is a unique digital fingerprint that is given to each and every file stored on a server. Since we store all content on a number of drives simultaneously, the same file has the same checksum on all the drives and what ZFS does is that it compares the checksums between the different drives in real time. When 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 possibility of the bad copy to be synchronized on the rest of the drives. ZFS is the only file system you will find which uses checksums, which makes it far superior to other file systems which are unable to identify silent data corruption and duplicate bad files across drives.
