Storage
In Active Backup for Business > Storage, you can monitor the status and storage usage of each shared folder when there is at least one backup task. You can also retrieve the existing data and task settings of Active Backup for Business by relinking the shared folders in this page.
To view the status and storage usage of each shared folder:
Click Storage. The following information of each shared folder will be displayed:
- Running tasks: Whether there is any running backup task.
- Device count: The number of backed-up devices in this shared folder.
- Global deduplication ratio: The number calculated from original source data size divided by actual stored data size. For example, the original source data is 100GB which is also written to the disk, and then only 80GB data are stored on Synology NAS after deduplication. Then the deduplication ratio will be 100GB / 80GB = 1.25x. For the second backup with CBT, only changed data will be added instead of adding the whole data size again. If the transferred size of changed data is 10GB and 5GB data are stored on Synology NAS in the second backup, the deduplication ratio will be (100+10) / (80+5) = 1.29x.
- Freeable space: The storage space will be freed when the unused space reaches the value which was set in Settings > Settings.
