The process of files getting damaged caused by some hardware or software failure is referred to as data corruption and this is one of the main problems which hosting companies face because the larger a hard drive is and the more information is filed on it, the more likely it is for data to become corrupted. You'll find a couple of fail-safes, still often the information becomes corrupted silently, so neither the particular file system, nor the admins detect anything. Thus, a corrupted file will be handled as a good one and if the HDD is part of a RAID, that file will be duplicated on all other drives. Theoretically, this is done for redundancy, but in practice the damage will get even worse. The moment a given file gets damaged, it will be partly or entirely unreadable, which means that a text file will not be readable, an image file will show a random combination of colors if it opens at all and an archive will be impossible to unpack, so you risk sacrificing your site content. Although the most widespread server file systems have various checks, they often fail to find some problem early enough or require an extensive amount of time in order to check all files and the web hosting server will not be operational in the meantime.
No Data Corruption & Data Integrity in Hosting
The integrity of the data which you upload to your new hosting
account will be ensured by the ZFS file system which we employ on our cloud platform. The majority of hosting suppliers, like our firm, use multiple hard disk drives to keep content and considering that the drives work in a RAID, the same info is synchronized between the drives all of the time. In case a file on a drive is damaged for reasons unknown, however, it is likely that it will be reproduced on the other drives since other file systems do not offer special checks for that. In contrast to them, ZFS uses a digital fingerprint, or a checksum, for every single file. In case a file gets corrupted, its checksum will not match what ZFS has as a record for it, which means that the damaged copy will be swapped with a good one from a different hard disk drive. Because this happens right away, there's no possibility for any of your files to ever get corrupted.
No Data Corruption & Data Integrity in Semi-dedicated Hosting
If you get one of our semi-dedicated hosting
solutions, you won't have to be concerned about silent file corruption as we use ZFS - an advanced file system which monitors all the files in real time. Each time you upload a file to your hosting account, ZFS will assign a unique digital fingerprint to it - the so-called checksum. That file will be synced between a number of SSD drives for redundancy, so if one drive fails, the other ones will take over. ZFS compares the checksum of all the copies on the different drives and in case it detects a damaged copy, it replaces it with a healthy one from another drive. This happens right away, so there will be no threat for any part of your content at any time. In comparison, all the other file systems perform checks only after a system breakdown, but since they don't use anything similar to the checksums that ZFS uses, they won't detect silently corrupted files, so a corrupted copy could be replicated on the other disks as well and you can lose precious information. Because this isn't the case with ZFS, we're able to warrant the integrity of every single file you upload no matter what.
