Data corruption is the damage of info because of various software or hardware failures. Once a file is corrupted, it will no longer work properly, so an application will not start or shall give errors, a text file could be partially or fully unreadable, an archive file will be impossible to open and unpack, etc. Silent data corruption is the process of data getting harmed without any acknowledgement by the system or an admin, which makes it a significant problem for website hosting servers as fails are much more likely to occur on larger hard drives where substantial volumes of information are located. In case a drive is part of a RAID and the data on it is duplicated on other drives for redundancy, it is very likely that the bad file will be treated as a regular one and it'll be copied on all of the drives, making the harm permanent. A huge number of the file systems which run on web servers nowadays often cannot find corrupted files right away or they need time-consuming system checks during which the server is not functioning.
No Data Corruption & Data Integrity in Website Hosting
The integrity of the data that you upload to your new website hosting
account shall be guaranteed by the ZFS file system that we work with on our cloud platform. The vast majority of hosting suppliers, like our firm, use multiple HDDs to store content and considering that the drives work in a RAID, identical data is synchronized between the drives at all times. If a file on a drive gets damaged for some reason, however, it is more than likely that it will be reproduced on the other drives since other file systems don't feature special checks for this. Unlike them, ZFS works with a digital fingerprint, or a checksum, for each file. In the event that a file gets corrupted, its checksum will not match what ZFS has as a record for it, which means that the damaged copy will be swapped with a good one from another hard drive. Because this happens right away, there's no possibility for any of your files to ever get damaged.
No Data Corruption & Data Integrity in Semi-dedicated Servers
We have avoided any chance of files getting damaged silently as the servers where your semi-dedicated server
account will be created take advantage of a powerful file system named ZFS. Its advantage over alternative file systems is that it uses a unique checksum for every single file - a digital fingerprint that's checked in real time. Since we store all content on multiple SSD drives, ZFS checks whether the fingerprint of a file on one drive corresponds to the one on the rest of the drives and the one it has stored. In the event that there's a mismatch, the damaged copy is replaced with a good one from one of the other drives and considering that this happens in real time, there is no chance that a damaged copy could remain on our website hosting servers or that it could be copied to the other hard disks in the RAID. None of the other file systems work with such checks and in addition, even during a file system check right after a sudden blackout, none of them can discover silently corrupted files. In contrast, ZFS doesn't crash after a power failure and the continual checksum monitoring makes a time-consuming file system check obsolete.
