Data corruption is the unintended transformation of a file or the loss of info which often occurs during reading or writing. The reason can be hardware or software fail, and as a consequence, a file could become partially or entirely corrupted, so it will no longer work properly since its bits shall be scrambled or missing. An image file, for example, will no longer show an accurate 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. If such a problem occurs and it isn't found by the system or by an admin, the data will get corrupted silently and if this happens on a drive that is part of a RAID array where the data is synchronized between various different drives, the corrupted file shall be replicated on all the other drives and the damage will become long term. Numerous widely used file systems either don't offer real-time checks or don't have high quality ones which can detect an issue before the damage is done, so silent data corruption is a very common issue on hosting servers where large volumes of data are kept.
No Data Corruption & Data Integrity in Shared Website Hosting
We guarantee the integrity of the info uploaded in every shared website hosting
account which is generated on our cloud platform because we work with the advanced ZFS file system. The latter is the only one which was designed to avoid silent data corruption through a unique checksum for each file. We will store your info on a large number of SSD drives which work in a RAID, so the very same files will be accessible on several places at the same time. ZFS checks the digital fingerprint of all the files on all the drives in real time and in the event that the checksum of any file is different from what it needs to be, the file system replaces that file with a healthy copy from some other drive from the RAID. There's no other file system that uses checksums, so it's possible for data to be silently corrupted and the bad file to be duplicated on all drives with time, but since this can never happen on a server running ZFS, you won't have to concern yourself with the integrity of your data.
No Data Corruption & Data Integrity in Semi-dedicated Hosting
You will not experience any kind of silent data corruption issues if you obtain one of our semi-dedicated hosting
plans since the ZFS file system that we take advantage of on our cloud hosting platform uses checksums in order to make sure that all of your files are intact all the time. A checksum is a unique digital fingerprint that is given to each and every file kept on a server. Due to the fact that we store all content on multiple drives simultaneously, the same file has the same checksum on all of the drives and what ZFS does is that it compares the checksums between the different drives right away. If 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 probability of the damaged copy to be synchronized on the other hard drives. ZFS is the sole file system available on the market which uses checksums, which makes it much more reliable than other file systems which are not able to identify silent data corruption and duplicate bad files across drives.
