Data corruption is the damage of info because of various software or hardware problems. After a file is corrupted, it will no longer function as it should, so an application will not start or will give errors, a text file can be partially or fully unreadable, an archive will be impossible to open and then unpack, etc. Silent data corruption is the process of info getting harmed without any acknowledgement by the system or an admin, which makes it a serious problem for website hosting servers as failures are more likely to occur on larger in size hard disk drives where substantial volumes of info are stored. When a drive is a part of a RAID and the info on it is duplicated on other drives for redundancy, it's very likely that the damaged file will be treated as a standard one and it'll be copied on all the drives, making the harm permanent. A huge number of the file systems that run on web servers today often cannot find corrupted files right away or they need time-consuming system checks during which the server isn't working.

No Data Corruption & Data Integrity in Cloud Web Hosting

We have dealt with the issue of silent data corruption on all of our cloud web hosting servers by using the modern Z file system, or ZFS. The latter is superior to other file systems since it is the only one in existence which checks all the files instantly by using a checksum - a digital identifier that is unique for each file. When you upload content to your account, it will be stored on several SSD drives and regularly synced between them for redundancy. ZFS constantly compares the checksum of all files and when any file is detected as corrupted, it's replaced quickly with a good copy from some other disk. As this happens in real time, there's no risk that a corrupted file may remain or may be duplicated on the remaining SSDs. ZFS requires lots of physical memory to perform the real-time checks and the advantage of our cloud web hosting platform is that we take advantage of multiple powerful servers working together. In case you host your Internet sites with us, your data will be intact no matter what.

No Data Corruption & Data Integrity in Semi-dedicated Hosting

Your semi-dedicated hosting account will be resistant to silent data corruption as all of our storage servers work with the advanced ZFS file system. What makes the aforementioned unique is that it uses checksums, or digital identifiers, so as to verify the integrity of each file. When you upload content to your account, it will be kept on a couple of redundant drives being employed in a RAID i.e. the files will be the same across all drives. All copies of a specific file will have the same checksum on all hard drives and ZFS will compare the checksums of the copies in real time, so if it identifies a mismatch, which would indicate that one of the copies is damaged, it will swap that file with a good copy from one of the other disks. Even if there's an unforeseen blackout, the data on the servers won't become corrupted and there won't be any need for a time-consuming system check that other file systems perform following some malfunction, lengthening the time needed for the server to get back online. ZFS is the file system that can really protect your content from silent data corruption.
