Data corruption is the unintentional change of a file or the losing of information that often occurs during reading or writing. The reason can be hardware or software fail, and consequently, a file can become partially or entirely corrupted, so it'll no longer function properly as its bits will be scrambled or lost. An image file, for instance, will no longer display an accurate image, but a random combination of colors, an archive will be impossible to unpack as its content will be unreadable, and so on. When this kind of an issue appears and it's not found by the system or by an administrator, the data will get corrupted silently and in case this happens on a drive that's part of a RAID array where the data is synchronized between various drives, the corrupted file shall be copied on all of the other drives and the damage will be long term. A large number of commonly used file systems either don't feature 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 rather common issue on internet hosting servers where large amounts of information are stored.
No Data Corruption & Data Integrity in Cloud Hosting
We guarantee the integrity of the information uploaded in every cloud hosting account that is made on our cloud platform since we work with the advanced ZFS file system. The aforementioned is the only one which was designed to avoid silent data corruption using a unique checksum for each and every file. We'll store your data on a large number of NVMe drives which operate in a RAID, so exactly the same files will be present on several places at the same time. ZFS checks the digital fingerprint of all of the files on all of 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 an undamaged copy from a different drive within the RAID. No other file system uses checksums, so it's easy for data to become silently corrupted and the bad file to be duplicated on all drives with time, but since this can never happen on a server using ZFS, you do not have to concern yourself with the integrity of your data.
No Data Corruption & Data Integrity in Semi-dedicated Servers
You will not experience any silent data corruption issues should you get one of our semi-dedicated server solutions as the ZFS file system that we use on our cloud hosting platform uses checksums in order to make sure that all files are undamaged at all times. A checksum is a unique digital fingerprint which is assigned 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 drives and what ZFS does is that it compares the checksums between the different drives in real time. In the event that 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 right away, avoiding any chance of the damaged copy to be synchronized on the other hard drives. ZFS is the only file system you will find which uses checksums, which makes it much more reliable than other file systems which cannot identify silent data corruption and copy bad files across hard drives.
