Improve disk space utilization
Traditional RAID 1 disk arrays use redundancy to mirror the data of one disk to another disk, which can effectively avoid the risk of data loss due to disk failure. But a RAID 1 disk array requires at least 2 disks, that is, in a RAID 1 disk array, at most 50% of the effective disk storage space is available. For some users, not all data is important data, and it may not be necessary to mirror the entire disk data. Before TerraMaster launched TFM Backup, RAID 1 array seemed to be the only choice when users made mirror backups of data on disks. Now, users can choose to use TFM Backup to selectively do mirror backup, which can increase the utilization of disk space while ensuring data security.
