Data corruption is the unintentional transformation of a file or the losing of information that often occurs during reading or writing. The reason may be hardware or software fail, and due to this fact, a file may become partially or fully corrupted, so it will no longer function as it should as its bits shall be scrambled or lacking. An image file, for instance, 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, and so on. When this kind of a problem occurs and it's not identified by the system or by an admin, the data will get corrupted silently and if this happens on a drive that's part of a RAID array where the data is synced between various drives, the corrupted file will be copied on all other drives and the damage will be permanent. Numerous widespread file systems either do not offer real-time checks or do not have high quality ones which can detect a problem before the damage is done, so silent data corruption is a very common problem on hosting servers where large volumes of data are kept.

No Data Corruption & Data Integrity in Cloud Web Hosting

In case you host your websites in a cloud web hosting account from our firm, you don't have to worry about 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 which uses checksums, or unique digital fingerprints, for each and every file. All information that you upload will be saved in a RAID i.e. simultaneously on multiple SSDs. All the file systems synchronize the files between the different drives with this kind of a setup, but there is no real warranty that a file will not get corrupted. This may happen during the writing process on each drive and afterwards a damaged copy may be copied on all other drives. What makes the difference on our platform is the fact that ZFS analyzes the checksums of all files on all drives in real time and when a corrupted file is found, it's replaced with a good copy with the correct checksum from some other drive. This way, your info will continue to be undamaged no matter what, even if an entire drive fails.

No Data Corruption & Data Integrity in Semi-dedicated Servers

You will not experience any kind of silent data corruption issues whatsoever if you get one of our semi-dedicated server plans due to the fact that the ZFS file system that we work with on our cloud hosting platform uses checksums to guarantee that all of the files are intact all the time. A checksum is a unique digital fingerprint that is allotted to each and every file saved on a server. As we store all content on a number of drives at the same time, 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 right away. When it detects that a file is corrupted and its checksum is different from what it has to be, it replaces that file with a healthy copy without delay, avoiding any chance of the damaged copy to be synchronized on the remaining hard drives. ZFS is the sole file system on the market which uses checksums, which makes it much more reliable than other file systems that are unable to identify silent data corruption and duplicate bad files across drives.
