When two servers are configured as a high availability cluster, data is mirrored automatically. If you cannot tolerate any downtime to restore data, the most effective method to protect the data on your online storage is to mirror it to an identical secondary server.LTO tapes are a safe, and fast way to backup, archive, and restore high volumes of data. If you ever lose all the data on your online storage and have to rebuild it from a backup, be aware that individual external hard drives are very slow.This adds additional redundancy (two drives) and prevents your data from being at risk during a drive rebuild. If you have a larger 8-drive RAID, you can consider RAID 6. This protects your data from a single drive failure in the array. Configure your RAID storage for redundancy using RAID 5.This can be pairs of cloned external hard drives, or even LTO tape using a desktop LTO tape drive. However, always duplicate your media to other offline storage. You can use a direct attached RAID, or a shared NAS as your primary working online storage.Clone is for making data available to use in a different location.īackup is for recovery from hardware failure or recent data corruption or loss.Īrchive is for space management and long term retention.Offline Storage is medium term storage of data that is not attached or instantly accessible. Nearline Storage is attached storage for short term data that needs to be instantly accessible, but doesn’t require the speed of the online storage. Online Storage is high speed attached working storage for instant access to active video media and other files.If a file doesn’t exist in three places, it doesn’t exist.I've been researching thunderbolt motherboards and PCI-E cards and found some information about what I likely will need. We have several Promise Pegasus 2 R6 and R8 units already in possession (so this is thunderbolt 2), we love the product and obviously would like to continue using these, even on the Windows machines. One of the final puzzles I need to solve, is the possibility of thunderbolt 2 and 3. We are contemplating making a switch from Mac OS to a Windows based system in some of our edit suites.
