Data corruption is the accidental modification of a file or the losing of info that usually occurs during reading or writing. The reason can be hardware or software fail, and due to this fact, a file could become partially or entirely corrupted, so it'll no longer work as it should as its bits will be scrambled or lost. An image file, for instance, will no longer show an actual image, but a random mix of colors, an archive will be impossible to unpack because its content will be unreadable, etc. In the event that such an issue occurs and it's not found by the system or by an administrator, the data will become corrupted silently and in case this happens on a disk drive that is part of a RAID array where the information is synced between various different drives, the corrupted file shall be replicated on all of the other drives and the damage will become long term. Numerous frequently used file systems either do not have real-time checks or don't have good ones which will detect a problem before the damage is done, so silent data corruption is a rather common issue on web hosting servers where large volumes of data are kept.
No Data Corruption & Data Integrity in Hosting
We warrant the integrity of the information uploaded in every hosting account that is made on our cloud platform as we work with the advanced ZFS file system. The aforementioned is the only one that was designed to avert silent data corruption via a unique checksum for each and every file. We will store your info on a number of NVMe drives that operate in a RAID, so identical files will be available on several places simultaneously. ZFS checks the digital fingerprint of all files on all the drives in real time and if the checksum of any file is different from what it should be, the file system swaps that file with an undamaged copy from a different drive within the RAID. No other file system uses checksums, so it is possible for data to get silently corrupted and the bad file to be reproduced on all drives with time, but since that can never happen on a server using ZFS, you will not have to concern yourself with the integrity of your data.
No Data Corruption & Data Integrity in Semi-dedicated Hosting
In case you buy one of our semi-dedicated hosting solutions, you will not have to be concerned about silent file corruption as we use ZFS - an advanced file system which keeps track of all 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 couple of NVMe 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 a different drive. This is done instantly, so there will be no threat for any part of your content at any moment. In comparison, all of the other file systems carry out checks after a system breakdown, but since they do not use anything similar to the checksums which ZFS uses, they will not detect silently corrupted files, so a corrupted copy may be replicated on the rest of the drives as well and you could lose important info. As this is not the case with ZFS, we are able to warrant the integrity of each and every file you upload no matter what.
