Data corruption is the unintended transformation of a file or the loss of information that often occurs during reading or writing. The reason can be hardware or software fail, and consequently, a file could become partially or entirely corrupted, so it will no longer function properly since its bits will be scrambled or lost. An image file, for instance, will no longer present an authentic image, but a random combination of colors, an archive will be impossible to unpack since its content will be unreadable, and so on. When such an issue appears and it's not found by the system or by an administrator, the data will get corrupted silently and when this happens on a disk drive that's part of a RAID array where the data is synchronized between various different drives, the corrupted file shall be reproduced on all other drives and the damage will become permanent. A large number of frequently used file systems either don't feature real-time checks or don't have good ones which can detect an issue before the damage is done, so silent data corruption is a rather common problem on hosting servers where huge amounts of info are stored.
No Data Corruption & Data Integrity in Cloud Website Hosting
In case you host your websites in a cloud website hosting
account from our company, you will not need to worry about any of your data ever getting damaged. We can ensure that as our cloud hosting platform uses the outstanding ZFS file system. The aforementioned is the only file system which uses checksums, or unique digital fingerprints, for each and every file. Any kind of info that you upload will be kept in a RAID i.e. simultaneously on many SSD drives. All of the file systems synchronize the files between the separate drives using this kind of a setup, but there is no real warranty that a file won't be corrupted. This could happen throughout the writing process on any drive and after that a corrupted copy may be copied on the other drives. What makes the difference on our platform is that ZFS compares the checksums of all files on all the drives right away and in case a corrupted file is identified, it's substituted with a good copy with the correct checksum from some other drive. By doing this, your info will stay intact no matter what, even if a whole drive fails.
No Data Corruption & Data Integrity in Semi-dedicated Servers
Your semi-dedicated server
account will be protected against silent data corruption as all our storage servers work with the innovative ZFS file system. What makes the aforementioned unique is that it uses checksums, or digital identifiers, so as to ensure the integrity of each and every file. When you upload content to your account, it will be kept on a couple of redundant drives employed in a RAID i.e. the files shall be the same on all disk drives. All of the copies of a given file will feature the same checksum on all hard disks and ZFS will compare the checksums of the duplicates quickly, and if it discovers a mismatch, that would indicate that one of the copies is damaged, it will swap that file with a good copy from one of the other disks. Even if there's an unexpected power failure, the data on the servers won't get corrupted and there will not be any need for a time-consuming system check which other file systems perform following some failure, lengthening the time needed for the server to get back online. ZFS is the sole file system which can truly protect your content from silent data corruption.
