The process of files being damaged caused by some hardware or software failure is called data corruption and this is one of the main problems which hosting companies face as the larger a hard disk is and the more information is stored on it, the more likely it is for data to get corrupted. You can find several fail-safes, still often the information gets corrupted silently, so neither the file system, nor the administrators notice anything. As a result, a bad file will be treated as a regular 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 worse. Once a file gets corrupted, it will be partially or entirely unreadable, so a text file will not be readable, an image file will display a random combination of colors in case it opens at all and an archive shall be impossible to unpack, so you risk sacrificing your website content. Although the most widespread server file systems include various checks, they are likely to fail to identify some problem early enough or require a long time period in order to check all files and the server will not be functional in the meantime.
No Data Corruption & Data Integrity in Hosting
In case you host your websites in a hosting
account from our company, you do not need to worry about any of your data ever getting corrupted. We can ensure that because our cloud hosting platform employs the reliable ZFS file system. The latter is the only file system which works with checksums, or unique digital fingerprints, for each file. Any kind of info that you upload will be kept in a RAID i.e. simultaneously on many SSD drives. All file systems synchronize the files between the separate drives with this type of a setup, but there's no real warranty that a file will not get corrupted. This may occur during the writing process on each drive and afterwards a damaged copy can be copied on all other drives. What makes the difference on our platform is that ZFS compares the checksums of all files on all drives live and if a corrupted file is located, it is substituted with a good copy with the correct checksum from some other drive. This way, your info will stay unharmed no matter what, even if a whole drive fails.
No Data Corruption & Data Integrity in Semi-dedicated Hosting
You will not have to deal with any silent data corruption issues in case you buy one of our semi-dedicated hosting
solutions due to the fact that the ZFS file system that we take advantage of on our cloud hosting platform uses checksums to ensure that all files are undamaged all of 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 multiple drives at the same time, 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. 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 probability of the damaged copy to be synchronized on the remaining hard disks. ZFS is the only file system out there that uses checksums, which makes it much more reliable than other file systems which cannot detect silent data corruption and copy bad files across hard drives.
