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.
