MSDP encryption behavior and compatibilities
MSDP supports multiple encryption algorithms. Therefore, it manages both the Blowfish and the AES encrypted data to ensure data compatibility.
For restore operations, MSDP recognizes the Blowfish data and the AES data to be able to restore the old backup images.
The following tables describe the encryption behavior for backup, duplication, and replication operations when the encryption is in progress.
Table: Encryption behavior for a backup operation to a NetBackup 8.0 storage server
| Type of client | Data encryption format |
|---|---|
|
Client with NetBackup 8.0, including the Client Direct deduplication |
AES |
|
Client with NetBackup version earlier than 8.0, excluding Client Direct deduplication |
AES |
|
Client with NetBackup version earlier than 8.0, using the Client Direct deduplication |
AES (using inline data conversion) |
|
Load balancing server with NetBackup version 8.0 |
AES |
|
Load balancing server with NetBackup version earlier than 8.0 |
AES (using inline data conversion) |
Table: Encryption behavior for optimized duplication and Auto Image Replication operations to a NetBackup 8.0 target server
| Type of source storage | Data encryption format for the duplication or the replication data that is encrypted with AES | Data encryption format for the duplication or the replication data that is encrypted with Blowfish |
|---|---|---|
|
Source server with NetBackup 8.0 |
AES |
AES (using inline data conversion) |
|
Source server with NetBackup version earlier than 8.0 |
Not applicable |
AES (using inline data conversion) |
Note:
Inline data conversion takes place simultaneously while the backup, duplication, or replication operations are in progress.
