Data corruption is the damage of data due to various software or hardware problems. When a file gets damaged, it will no longer function correctly, so an application will not start or will give errors, a text file shall 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 serious problem for web hosting servers as failures are much more likely to happen on larger hard disk drives where substantial volumes of info are placed. If a drive is part of a RAID and the information on it is duplicated on other drives for redundancy, it's likely that the damaged file will be treated as a good one and will be copied on all drives, making the harm permanent. A huge number of the file systems that run on web servers today often are not able to discover corrupted files immediately or they need time-consuming system checks through which the server isn't working.
No Data Corruption & Data Integrity in Shared Hosting
The integrity of the data that you upload to your new shared hosting
account shall be ensured by the ZFS file system that we use on our cloud platform. The vast majority of web hosting service providers, like our firm, use multiple hard disk drives to store content and because the drives work in a RAID, the exact same information is synchronized between the drives at all times. When a file on a drive becomes damaged for reasons unknown, yet, it's more than likely that it will be copied on the other drives since alternative file systems don't include special checks for that. In contrast to them, ZFS uses a digital fingerprint, or a checksum, for every file. In case a file gets corrupted, its checksum will not match what ZFS has as a record for it, so the bad copy will be swapped with a good one from a different hard disk drive. Because this happens in real time, there's no possibility for any of your files to ever be corrupted.
No Data Corruption & Data Integrity in Semi-dedicated Hosting
You won't experience any kind of silent data corruption issues if you buy one of our semi-dedicated hosting
plans because the ZFS file system that we employ on our cloud hosting platform uses checksums in order to make sure that all files are intact all the time. A checksum is a unique digital fingerprint which is given to each and every file kept on a server. As we store all content on a number of drives simultaneously, 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. 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 possibility of the damaged copy to be synchronized on the rest of the hard drives. ZFS is the sole file system on the market which uses checksums, which makes it far superior to other file systems which cannot detect silent data corruption and duplicate bad files across drives.
