- Block level incremental backups.
Automatic incremental backups track file and block level changes, only transferring the changed blocks, hence reducing the storage and bandwidth utilization.
- Data compression, encryption and throttling.
Data is compressed and encrypted on the server before being sent to Windows Azure over the network. As a result, Windows Azure Online Backup only places encrypted data in the cloud storage.
- Data integrity verified in the cloud.
Backed up data is also automatically checked for integrity once the backup is complete. As a result, any corruptions due to data transfer are automatically identified and repair is attempted in the next backup.
- Configurable retention policies.
Configure and implement retention policies to help meet business policies and manage backup costs.
