Data corruption is the damage of data because of various hardware or software failures. After a file gets corrupted, it will no longer function as it should, so an app will not start or will give errors, a text file could be partially or entirely unreadable, an archive file will be impossible to open then unpack, etc. Silent data corruption is the process of data getting damaged without any identification by the system or an administrator, which makes it a serious problem for website hosting servers as problems are very likely to happen on larger hard disks where substantial volumes of information are located. In case a drive is a part of a RAID and the information on it is copied on other drives for redundancy, it is very likely that the damaged file will be treated as a standard one and it'll be duplicated on all of the drives, making the damage permanent. Lots of the file systems which operate on web servers today often cannot recognize corrupted files immediately or they need time-consuming system checks through which the server is not operational.

No Data Corruption & Data Integrity in Cloud Website Hosting

We warrant the integrity of the information uploaded in every single cloud website hosting account which is made on our cloud platform as we use the advanced ZFS file system. The latter is the only one that was designed to avoid silent data corruption thanks to a unique checksum for each and every file. We will store your data on a large number of SSD drives which function in a RAID, so the very same files will be present on several places simultaneously. ZFS checks the digital fingerprint of all files on all drives in real time and in case the checksum of any file differs from what it should be, the file system replaces that file with a healthy copy from a different drive inside the RAID. No other file system uses checksums, so it is easy for data to become silently damaged and the bad file to be reproduced on all drives with time, but since this can never happen on a server running ZFS, you won't have to worry about the integrity of your information.

No Data Corruption & Data Integrity in Semi-dedicated Servers

You will not experience any silent data corruption issues whatsoever should you purchase one of our semi-dedicated server plans since the ZFS file system that we employ on our cloud hosting platform uses checksums in order to ensure that all the files are undamaged all of the time. A checksum is a unique digital fingerprint which is given to each and every file saved on a server. Because we store all content on a number of drives simultaneously, the same file uses the same checksum on all of the drives and what ZFS does is that it compares the checksums between the different drives right away. 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 bad copy to be synchronized on the other hard disks. ZFS is the sole file system out there that uses checksums, which makes it far superior to other file systems which cannot detect silent data corruption and duplicate bad files across hard drives.
