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.
- Data reduction ratio: The ratio of the original source data size to the actual stored data size. With deduplication and compression technologies provided by Active Backup for Business, actual stored data size could be lower than the original source data size. In other words, the higher this ratio is, the more space is saved.
- Backed up data size: The number indicates the original size of the backup data which have not been deduplicated and compressed by Active Backup for Business. It is the total size of the first backup and the changed data after the first backup, excluding the size of deleted backup versions.
- Space saved by deduplication: The number indicates the size of the duplicated backup data which have been removed by Active Backup for Business.
- Space saved by data compression: The number indicates the space saved after compression at destination has been processed.
- Storage usage: The number indicates the actual space used by the shared folder. (Backed up data size subtracted by Space saved by deduplication and Space saved by data compression)
- File server raw data: The original size of file server data. Please note that if the backup mode of the file server backup task is multi-versioned, the number displayed here might be larger than the actual space consumed by file server backed up data.
Note:
- Active Backup for Business does not support encryption and compression for file server tasks. However, file servers can be backed up to compressed or encrypted DSM shared folders. For more information on encrypted DSM shared folders, please refer to this article.
To retrieve the existing data and task settings of Active Backup for Business:

To learn more about Snapshot Replication, please refer to this help article.
- Hyper Backup: Besides backing up shared folders to another Synology NAS, you have more choices of backup destinations via Hyper Backup, such as USB, file servers, and other cloud services. Please make sure that you select the "@ActiveBackup" folder in the ActiveBackupforBusiness shared folder when backing up Active Backup for Business via Hyper Backup. For more information about creating copies of the shared folder, please refer to this help article.
To mount the storage for restoring the encrypted data:
If you wish to restore data from a backup task that is encrypted at destination, first make sure that the backup destination is mounted. Please follow the steps below to mount the backup destination.
- Go to Storage and click Mount Settings.
- Click Mount.
- Enter the password or upload the encryption key to mount the encrypted backup destination for restoration.
- You can enable Mount backup destination when this Synology NAS restarts to quickly mount this shared folder whenever the Synology NAS or Active Backup for Business restarts.
Note:
- After you enabled Mount backup destination when this Synology NAS restarts, please make sure the encryption key is at the selected location every time you restart.
- For data security, it is recommended that you select an external device as the location to store the encryption key. The encryption key will be encrypted again by an unique machine key of the Synology NAS. Thus, even when the external device where the key stored is lost or stolen, the backup data still cannot be decrypted by others who have no access to your Synology NAS.
