Data corruption is the damage of information due to various hardware or software problems. The moment a file is corrupted, it will no longer function accurately, so an app will not start or will give errors, a text file could be partially or completely unreadable, an archive will be impossible to open then unpack, etc. Silent data corruption is the process of information getting damaged without any identification by the system or an admin, which makes it a significant problem for website hosting servers as failures are very likely to occur on larger hard drives where large volumes of info are kept. In case a drive is part of a RAID and the information on it is replicated on other drives for redundancy, it is more than likely that the bad file will be treated as a good one and it'll be duplicated on all drives, making the harm permanent. A lot of the file systems that operate on web servers today often cannot recognize corrupted files right away or they need time-consuming system checks during which the server isn't working.

No Data Corruption & Data Integrity in Shared Website Hosting

The integrity of the data which you upload to your new shared website hosting account will be ensured by the ZFS file system which we make use of on our cloud platform. Most of the hosting providers, like our firm, use multiple hard disks to store content and because the drives work in a RAID, the exact same information is synchronized between the drives all the time. When a file on a drive becomes corrupted for some reason, yet, it is very likely that it will be copied on the other drives since other file systems don't have special checks for this. In contrast to them, ZFS applies 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, so the damaged copy will be swapped with a good one from another hard disk. Since this happens in real time, there's no risk for any of your files to ever be damaged.

No Data Corruption & Data Integrity in Semi-dedicated Servers

You will not have to deal with any kind of silent data corruption issues should you buy one of our semi-dedicated server solutions due to the fact that the ZFS file system that we work with on our cloud hosting platform uses checksums in order to make sure that all of the files are undamaged all the time. A checksum is a unique digital fingerprint which is allotted to each and every file kept on a server. As we store all content on multiple drives at the same time, the same file uses the same checksum on all 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 has to 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 disks. ZFS is the only file system you can find that uses checksums, which makes it far superior to other file systems which cannot detect silent data corruption and duplicate bad files across drives.
