Data corruption is the damage of information caused by various hardware or software failures. When a file is damaged, it will no longer function correctly, so an application will not start or will give errors, a text file could be partially or completely unreadable, an archive will be impossible to open and then unpack, etc. Silent data corruption is the process of data getting damaged without any acknowledgement by the system or an admin, that makes it a serious problem for web hosting servers as failures are more likely to occur on larger in size hard drives where considerable volumes of information are stored. In case a drive is part of a RAID and the data on it is replicated on other drives for redundancy, it is likely that the damaged file will be treated as a healthy one and it will be copied on all drives, making the damage permanent. A lot of the file systems which operate on web servers today often are unable to find corrupted files right away or they need time-consuming system checks during which the server is not operational.
No Data Corruption & Data Integrity in Website Hosting
The integrity of the data which you upload to your new website hosting
account shall be guaranteed by the ZFS file system that we employ on our cloud platform. The majority of hosting service providers, including our firm, use multiple hard disks to store content and because the drives work in a RAID, identical info is synchronized between the drives all the time. If a file on a drive gets corrupted for whatever reason, yet, it's more than likely that it will be duplicated on the other drives because alternative file systems do not offer special checks for this. Unlike them, ZFS works with a digital fingerprint, or a checksum, for each file. If a file gets corrupted, its checksum won't match what ZFS has as a record for it, therefore the damaged copy shall be substituted with a good one from a different hard disk drive. As this happens immediately, there is no risk for any of your files to ever get damaged.
No Data Corruption & Data Integrity in Semi-dedicated Hosting
You will not have to deal with any silent data corruption issues whatsoever should you purchase one of our semi-dedicated hosting
plans since the ZFS file system that we use on our cloud hosting platform uses checksums to guarantee that all files are intact all the time. A checksum is a unique digital fingerprint that is allotted to each and every file saved on a server. Due to the fact that we store all content on multiple drives simultaneously, the same file has the same checksum on all 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 has to be, it replaces that file with a healthy copy without delay, avoiding any chance of the bad copy to be synchronized on the rest of the drives. ZFS is the only file system on the market which uses checksums, which makes it much more reliable than other file systems which cannot detect silent data corruption and duplicate bad files across drives.
