Data corruption is the damage of data because of various hardware or software failures. After a file is damaged, it will no longer work as it should, so an app will not start or will give errors, a text file could be partially or fully unreadable, an archive will be impossible to open and then unpack, etc. Silent data corruption is the process of information getting damaged without any acknowledgement by the system or an admin, that makes it a significant problem for website hosting servers as fails are more likely to occur on bigger hard disks where large volumes of info are kept. In case a drive is a part of a RAID and the information on it is duplicated on other drives for redundancy, it's very likely that the bad file will be treated as a standard one and will be duplicated on all the drives, making the harm permanent. A lot of the file systems which run on web servers nowadays often are unable to discover corrupted files immediately or they need time-consuming system checks through which the server isn't operational.
No Data Corruption & Data Integrity in Cloud Hosting
The integrity of the data that you upload to your new cloud hosting
account will be ensured by the ZFS file system which we employ on our cloud platform. The majority of hosting providers, like our firm, use multiple hard disk drives to keep content and because the drives work in a RAID, exactly the same data is synchronized between the drives all the time. When a file on a drive is damaged for whatever reason, yet, it is very likely that it will be duplicated on the other drives since other file systems don't include special checks for that. In contrast to them, ZFS uses a digital fingerprint, or a checksum, for each file. In case a file gets corrupted, its checksum will not match what ZFS has as a record for it, therefore the damaged copy will be swapped with a good one from another hard drive. Since this happens instantly, there is no risk for any of your files to ever be damaged.
No Data Corruption & Data Integrity in Semi-dedicated Hosting
You will not encounter any kind of silent data corruption issues whatsoever should you buy one of our semi-dedicated hosting
solutions due to the fact that the ZFS file system that we work with on our cloud hosting platform uses checksums in order to guarantee that all of the files are intact all the time. A checksum is a unique digital fingerprint which is allotted to each and every file saved on a server. Since we store all content on multiple drives at the same time, 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 in real time. 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 without delay, avoiding any chance of the corrupted copy to be synchronized on the other drives. ZFS is the sole file system you can find that uses checksums, which makes it far superior to other file systems that are not able to detect silent data corruption and duplicate bad files across hard drives.
