Data corruption is the unintended transformation of a file or the loss of information which often occurs during reading or writing. The reason may be hardware or software fail, and for that reason, a file could become partially or fully corrupted, so it'll no longer function properly because its bits shall be scrambled or lost. 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 since its content will be unreadable, etc. In case such an issue appears and it is not 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 synced between various drives, the corrupted file will be reproduced on all other drives and the harm will be permanent. A large number of widespread file systems either do not have real-time checks or do not have high quality ones that can detect a problem before the damage is done, so silent data corruption is a common problem on web hosting servers where large amounts of data are stored.
No Data Corruption & Data Integrity in Hosting
We warrant the integrity of the data uploaded in each hosting account which is made on our cloud platform since we use the advanced ZFS file system. The latter is the only one which was designed to prevent silent data corruption thanks to a unique checksum for every single file. We shall store your data on multiple SSD drives that function in a RAID, so the very same files will be accessible on several places at once. 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 should be, the file system replaces that file with an undamaged copy from some other drive within the RAID. There's no other file system that uses checksums, so it is possible for data to become silently corrupted and the bad file to be reproduced on all drives with time, but since that can never happen on a server using ZFS, you do not have to worry about the integrity of your information.
