The process of files getting corrupted because of some hardware or software failure is known as data corruption and this is one of the main problems which hosting companies face because the larger a hard disk drive is and the more information is placed on it, the much more likely it is for data to be corrupted. There're various fail-safes, yet often the data is damaged silently, so neither the particular file system, nor the admins detect a thing. Because of this, a corrupted file will be treated as a good one and if the HDD is a part of a RAID, that particular file will be duplicated on all other drives. In principle, this is for redundancy, but in practice the damage will be even worse. When some file gets damaged, it will be partly or fully unreadable, therefore a text file will no longer be readable, an image file will show a random mix of colors in case it opens at all and an archive will be impossible to unpack, and you risk losing your content. Although the most widely used server file systems feature various checks, they quite often fail to find a problem early enough or require an extensive amount of time in order to check all the files and the server will not be functional in the meantime.
No Data Corruption & Data Integrity in Shared Hosting
In case you host your websites in a shared hosting
account from our company, you do not have to worry about your data ever getting damaged. We can ensure that as our cloud hosting platform employs the outstanding ZFS file system. The latter is the only file system which uses checksums, or unique digital fingerprints, for each file. Any information that you upload will be saved in a RAID i.e. simultaneously on a large number of SSD drives. Many file systems synchronize the files between the different drives with this type of a setup, but there's no real warranty that a file will not get corrupted. This could happen during the writing process on any drive and then a corrupted copy may be copied on all other drives. What is different on our platform is that ZFS compares the checksums of all files on all the drives immediately and when a corrupted file is discovered, it's substituted with a good copy with the correct checksum from some other drive. This way, your info will stay undamaged no matter what, even if an entire drive fails.
No Data Corruption & Data Integrity in Semi-dedicated Hosting
You will not need to deal with any kind of silent data corruption issues whatsoever should 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 of your files are intact at all times. A checksum is a unique digital fingerprint that is allotted to each and every file stored on a server. Because we store all content on a number of drives at the same time, the same file uses the same checksum on all of the drives and what ZFS does is that it compares the checksums between the different drives right away. When 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 rest of the drives. ZFS is the sole file system available on the market that uses checksums, which makes it much more dependable than other file systems which are not able to detect silent data corruption and copy bad files across hard drives.
