Data corruption is the damage of info caused by various hardware or software problems. Once a file gets corrupted, it will no longer function accurately, so an application will not start or shall give errors, a text file could be partially or completely unreadable, an archive file will be impossible to open then unpack, etc. Silent data corruption is the process of data getting damaged without any acknowledgement by the system or an administrator, which makes it a serious problem for hosting servers as fails are very likely to occur on larger in size hard disks where vast volumes of info are kept. If a drive is a part of a RAID and the data on it is replicated on other drives for redundancy, it is more than likely that the damaged file will be treated as a healthy one and it'll be duplicated on all of the drives, making the damage permanent. Lots of the file systems that run on web servers nowadays often are unable to identify corrupted files instantly or they need time-consuming system checks during which the server is not working.

No Data Corruption & Data Integrity in Cloud Hosting

We've resolved the matter of silent data corruption on all our cloud hosting servers by using the leading-edge Z file system, or ZFS. The latter is superior to other file systems because it is the only one on the market that checks all the files in real time by employing a checksum - a digital identifier that's 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 in case any file is detected as damaged, it is replaced promptly with a good copy from another disk. As this happens in real time, there is no risk that a damaged file may remain or may be duplicated on the rest of the SSDs. ZFS needs lots of physical memory to perform the real-time checks and the benefit of our cloud website hosting platform is that we take advantage of multiple powerful servers working together. In case you host your Internet sites with us, your info will be undamaged no matter what.

No Data Corruption & Data Integrity in Semi-dedicated Hosting

You will not have to deal with any silent data corruption issues in case you acquire one of our semi-dedicated hosting plans since the ZFS file system that we employ on our cloud hosting platform uses checksums in order to guarantee that all files are intact all the time. A checksum is a unique digital fingerprint which is assigned to each and every file stored on a server. Since we store all content on a number of drives simultaneously, the same file uses the same checksum on all the drives and what ZFS does is that it compares the checksums between the different drives right away. In case 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 damaged copy to be synchronized on the remaining drives. ZFS is the only file system on the market which uses checksums, which makes it much more reliable than other file systems which are unable to identify silent data corruption and copy bad files across hard drives.
