Data corruption is the unintended transformation of a file or the losing of information that usually occurs during reading or writing. The reason could be hardware or software failure, and for that reason, a file may become partially or fully corrupted, so it will no longer work as it should as its bits will be scrambled or missing. An image file, for instance, will no longer display an authentic image, but a random combination of colors, an archive will be impossible to unpack since its content will be unreadable, etc. When such a problem occurs and it is not noticed by the system or by an administrator, the data will be corrupted silently and in case this happens on a disk drive that's part of a RAID array where the info is synced between various different drives, the corrupted file will be reproduced on all the other drives and the damage will be permanent. A number of frequently used file systems either don't feature real-time checks or do not have high quality ones which can detect a problem before the damage is done, so silent data corruption is a very common matter on web hosting servers where large volumes of data are stored.
No Data Corruption & Data Integrity in Cloud Hosting
If you host your sites in a cloud hosting
account with our firm, you do not need to worry about your data ever getting damaged. We can ensure that due to the fact that our cloud hosting platform employs the revolutionary ZFS file system. The latter is the only file system which uses checksums, or unique digital fingerprints, for every single file. All the information that you upload will be kept in a RAID i.e. simultaneously on numerous SSDs. A lot of file systems synchronize the files between the separate drives using this kind of a setup, but there's no real guarantee that a file won't get corrupted. This may occur during the writing process on each drive and then a damaged copy can be copied on the rest of the drives. What is different on our platform is the fact that ZFS compares the checksums of all files on all drives immediately 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 information 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 use the effective ZFS file system. What makes the latter unique is that it uses checksums, or digital identifiers, in order to guarantee the integrity of every single file. When you upload content to your account, it'll be placed on several redundant drives being employed in a RAID i.e. the files shall be the same on all disk drives. All copies of a specific file will have the same checksum on all drives and ZFS will compare the checksums of the copies right away, and if it detects a mismatch, which will 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 a sudden power failure, the data on the servers will not be corrupted and there will not be any need for a time-consuming system check that other file systems perform after some failure, extending the time needed for the server to get back online. ZFS is the only file system which can truly protect your content from silent data corruption.
