Data corruption is the damage of info caused by various software or hardware fails. Once a file gets damaged, it will no longer work as it should, so an application will not start or will give errors, a text file can be partially or entirely unreadable, an archive will be impossible to open then unpack, etc. Silent data corruption is the process of info getting damaged without any acknowledgement by the system or an administrator, that makes it a significant problem for web hosting servers as fails are much more likely to occur on larger in size hard disk drives where substantial volumes of info are placed. If a drive is a part of a RAID and the info on it is replicated on other drives for redundancy, it is more than likely that the damaged file will be treated as a standard one and will be copied on all the drives, making the harm permanent. Lots of the file systems that operate on web servers today often are not able to locate corrupted files in real time or they need time-consuming system checks during which the server isn't operational.
No Data Corruption & Data Integrity in Shared Website Hosting
We guarantee the integrity of the data uploaded in every single shared website hosting
account that is generated on our cloud platform due to the fact that we use the advanced ZFS file system. The aforementioned is the only one which was designed to avert silent data corruption thanks to a unique checksum for every single file. We'll store your information on a number of SSD drives which work in a RAID, so the very same files will be available on several places concurrently. ZFS checks the digital fingerprint of all of the files on all the drives in real time and in case the checksum of any file differs from what it has to be, the file system swaps that file with an undamaged copy from some other drive inside the RAID. No other file system uses checksums, so it's possible for data to be silently damaged and the bad file to be duplicated on all drives with time, but since this can never happen on a server running ZFS, you don't have to worry about the integrity of your information.
No Data Corruption & Data Integrity in Semi-dedicated Servers
You won't encounter any silent data corruption issues whatsoever should you purchase one of our semi-dedicated server
solutions because the ZFS file system that we take advantage of on our cloud hosting platform uses checksums to ensure that all the files are undamaged all of the time. A checksum is a unique digital fingerprint that is assigned to each and every file saved on a server. As we store all content on multiple 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 in real time. When 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 chance of the corrupted copy to be synchronized on the remaining 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 are not able to identify silent data corruption and copy bad files across hard drives.
