Data corruption is the damage of info due to various software or hardware fails. Once a file gets corrupted, it will no longer work properly, so an app will not start or shall give errors, a text file could be partially or entirely unreadable, an archive will be impossible to open and then unpack, etc. Silent data corruption is the process of info getting harmed without any identification by the system or an administrator, that makes it a significant problem for hosting servers as failures are more likely to occur on larger hard disk drives where vast volumes of info are stored. If a drive is a part of a RAID and the information on it is replicated on other drives for redundancy, it's more than likely that the bad file will be treated as a healthy one and will be duplicated on all drives, making the harm permanent. Lots of the file systems that operate on web servers today often cannot detect corrupted files immediately or they need time-consuming system checks during which the server is not functioning.
No Data Corruption & Data Integrity in Cloud Hosting
We warrant the integrity of the data uploaded in any cloud hosting
account which is made on our cloud platform because we work with the advanced ZFS file system. The latter is the only one that was designed to avert silent data corruption via a unique checksum for each and every file. We will store your data on multiple SSD drives which function in a RAID, so the exact same files will be present 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 case the checksum of any file is different from what it needs to be, the file system replaces that file with a healthy version from some other drive within the RAID. There's no other file system which uses checksums, so it's possible for data to get silently corrupted and the bad file to be reproduced on all drives over time, but since this can never happen on a server using ZFS, you will not have to worry about the integrity of your information.
