Data corruption is the unintended transformation of a file or the loss of information which often occurs during reading or writing. The reason can be hardware or software fail, and for that reason, a file can become partially or entirely corrupted, so it will no longer work as it should because its bits shall be scrambled or missing. An image file, for instance, will no longer show an accurate image, but a random combination of colors, an archive will be impossible to unpack because its content will be unreadable, etc. In case this kind of a problem occurs and it's not found by the system or by an admin, the data will get corrupted silently and if this happens on a disk drive that's a part of a RAID array where the data is synchronized between various different drives, the corrupted file will be replicated on all other drives and the damage will be long term. Many frequently used file systems either do not offer real-time checks or do not have good ones that will detect a problem before the damage is done, so silent data corruption is a common issue on web hosting servers where substantial volumes of data are stored.

No Data Corruption & Data Integrity in Hosting

If you host your Internet sites in a hosting account from our firm, you won't have to worry about any of your data ever getting damaged. We can guarantee that due to the fact that our cloud hosting platform works with the outstanding ZFS file system. The latter is the only file system that works with checksums, or unique digital fingerprints, for each file. Any kind of information that you upload will be kept in a RAID i.e. simultaneously on many different NVMes. Many file systems synchronize the files between the separate drives using this type of a setup, but there is no real warranty that a file will not be corrupted. This can occur at the time of the writing process on any drive and then a damaged copy can be copied on the rest of the drives. What is different on our platform is the fact that ZFS analyzes the checksums of all files on all of the drives instantly and in case a corrupted file is identified, it is swapped with a good copy with the correct checksum from another drive. In this way, your data will stay undamaged no matter what, even if a whole drive fails.

No Data Corruption & Data Integrity in Semi-dedicated Servers

You won't need to deal with any silent data corruption issues should you buy one of our semi-dedicated server packages because the ZFS file system that we take advantage of on our cloud hosting platform uses checksums in order to guarantee that all the files are intact all the time. A checksum is a unique digital fingerprint which is allotted to each and every file kept on a server. Because we store all content on a number of drives simultaneously, 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 right away, avoiding any possibility of the bad copy to be synchronized on the other hard drives. ZFS is the sole file system out there which uses checksums, which makes it much more dependable than other file systems which are not able to detect silent data corruption and duplicate bad files across drives.
