Unlimited backups. No license necessary.
Active Backup for Microsoft 365 is a free add-on application coming with your Synology NAS. Select an ideal Synology NAS to back up unlimited user accounts, as long as storage capacity allows – completely free of licenses.
Your NAS, your control
Businesses can enable continuous backup to minimize the risk of data loss while flexibly preserving backup versions by setting a specific time period for file retention.
Continuous backup
Continuous backup allows businesses to back up users' services in a non-stop manner, thereby minimizing the risk of data loss.
Flexible file versioning
If changes are made, data will be backed up. When a backed-up file is updated to a new version, its previous version will be preserved for the period of time you set for file retention, so that at least the previous version will be available for restoration.
Storage efficiency
Minimize required storage space with single instancing and block-level deduplication, so that identical items will only be stored to Synology NAS once.
Recovery
Go beyond public cloud's native recovery capabilities and default retention period. Save time with instant search and perform granular recovery of an individual object – whenever you need it.
