Data corruption is the damage of info caused by various software or hardware failures. The moment a file is damaged, it will no longer work accurately, so an app will not start or will give errors, a text file will be partially or completely unreadable, an archive file will be impossible to open and then unpack, etc. Silent data corruption is the process of info getting damaged without any acknowledgement by the system or an administrator, that makes it a significant problem for hosting servers as failures are more likely to occur on larger in size hard disk drives where large volumes of info are located. If a drive is part of a RAID and the info on it is copied on other drives for redundancy, it's more than likely that the bad file will be treated as a regular one and will be duplicated on all drives, making the harm permanent. Lots of the file systems that run on web servers today often are unable to locate corrupted files instantly or they need time-consuming system checks during which the server isn't functioning.
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 that we work with on our cloud platform. Most of the web hosting suppliers, including our firm, use multiple hard disk drives to keep content and because the drives work in a RAID, the same information is synchronized between the drives all the time. In case a file on a drive is corrupted for reasons unknown, yet, it is more than likely that it will be copied on the other drives as other file systems don't include special checks for this. In contrast to them, ZFS applies a digital fingerprint, or a checksum, for every file. In the event that a file gets corrupted, its checksum will not match what ZFS has as a record for it, and the damaged copy will be swapped with a good one from a different hard disk drive. As this happens immediately, there's no risk for any of your files to ever be corrupted.
No Data Corruption & Data Integrity in Semi-dedicated Servers
You won't experience any silent data corruption issues in case you buy one of our semi-dedicated server solutions as the ZFS file system that we take advantage of on our cloud hosting platform uses checksums to ensure that all files are undamaged all the time. A checksum is a unique digital fingerprint that is given to each and every file stored on a server. Since we store all content on a number of drives at the same time, the same file has the same checksum on all the drives and what ZFS does is that it compares the checksums between the different drives in real time. 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 possibility of the damaged copy to be synchronized on the other drives. ZFS is the sole file system on the market which uses checksums, which makes it much more dependable than other file systems which are unable to detect silent data corruption and copy bad files across hard drives.
