/ Mirror backup, can only choose RAID 1?

When it comes to mirror data backup, most people will mention RAID 1.

RAID 1 realizes data redundancy through disk data mirroring, and generates mutually backup data on pairs of independent disks. When the original data is busy, data can be read directly from the mirrored copy. When a disk fails, the system can automatically switch to read and write on the mirror disk without reorganizing the failed data, thus providing high data security and availability. But RAID 1 has the highest unit cost among disk arrays and also has its own limitations. Therefore, TerraMaster has added a very practical backup tool--TFM Backup for users in TOS 5.  


TFM Backup is the abbreviation of TerraMaster Folder Mirror backup. TFM Backup is a dedicated backup tool for TNAS shared folders developed by TerraMaster. Through TFM Backup, you can easily backup the shared folders in TNAS to other local folders. Storage location or a remotely mounted folder. TFM Backup has mirror backup and differential backup to choose from, and users can realize automatic scheduled backup by configuring backup schedule tasks. TFM Backup provides users with a simple and flexible backup solution for backing up data in TNAS.

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.


Flexible backup strategy
TFM Backup has two backup strategies: mirror backup and differential backup. In the mirror backup mode, the backup source data is always consistent with the destination data, which can reduce the work of data management; in the differential backup mode, the newly added or modified data is backed up, even if the source data is deleted, the destination The data always retains the last backup version, which can effectively avoid the loss caused by misoperation.



Custom backup plan
TFM Backup provides a customizable backup plan, and you can customize the backup time, period, and frequency. You can perform backups during less busy periods according to business needs to avoid disruption to normal business.


Multiple backup tasks
TFM Backup supports multiple backup tasks. You can use TFM Backup to create multiple backup tasks for multiple folders with different backup policies and destinations, and configure different task schedules for each task to meet the backup needs of different file types in various application scenarios.

Flexible backup destination
The backup destination of TFM Backup can be in a different storage pool, a different volume, or a different device (using a remotely mounted folder). To avoid data loss caused by disk hardware failure, it is recommended to set the backup destination to a volume in a different storage pool.

TFM Backup will be officially released in the TOS 5 operating system in June. For more details, please key attention to TerraMaster official update.
