Data corruption is the damage of information because of various hardware or software failures. Once a file is corrupted, it will no longer function accurately, so an app will not start or shall give errors, a text file will be partially or completely unreadable, an archive file will be impossible to open and unpack, etc. Silent data corruption is the process of data getting damaged without any identification by the system or an admin, which makes it a significant problem for web hosting servers as problems are very likely to occur on bigger hard disks where significant volumes of info are stored. If a drive is part of a RAID and the info on it is replicated 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 drives, making the damage permanent. A lot of the file systems which operate on web servers nowadays often cannot recognize corrupted files right away or they need time-consuming system checks through which the server is not working.
No Data Corruption & Data Integrity in Shared Hosting
We guarantee the integrity of the info uploaded in each and every shared hosting
account which is generated on our cloud platform since we work with the advanced ZFS file system. The latter is the only one which was designed to avoid silent data corruption through a unique checksum for each file. We will store your information on a large number of SSD drives which operate in a RAID, so the very same files will be present on several places at once. ZFS checks the digital fingerprint of all of the files on all drives in real time and if the checksum of any file is different from what it has to be, the file system swaps that file with an undamaged copy from a different drive within the RAID. No other file system uses checksums, so it is possible for data to be silently corrupted 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 concern yourself with the integrity of your data.
No Data Corruption & Data Integrity in Semi-dedicated Hosting
You will not have to deal with any kind of silent data corruption issues whatsoever should you purchase one of our semi-dedicated hosting
plans as the ZFS file system that we use on our cloud hosting platform uses checksums to guarantee that all the files are intact all the time. A checksum is a unique digital fingerprint which is assigned to each and every file kept on a server. Because we store all content on multiple 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 right away. In the event that 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 other hard disks. ZFS is the sole file system out there which uses checksums, which makes it much more dependable than other file systems which are not able to identify silent data corruption and duplicate bad files across hard drives.
