Restore
In the restore workflow, there can be two DTE scenarios:
When the image DTE mode is Off
When the image DTE mode is On
In either of the scenarios, there can be one or more media servers involved (if multiple images are selected) while restoring data on a client for single NetBackup job.
Table: Media server DTE mode is On (default)
Global DTE mode | DTE mode of NetBackup client 9.1 or later | NetBackup host (media server or client) earlier than 9.1 | ||
---|---|---|---|---|
On | Off | Automatic | ||
Preferred Off | Data is encrypted | Data is not encrypted | Data is not encrypted | Data is not encrypted |
Preferred On | Data is encrypted | Data is not encrypted | Data is encrypted | Data is not encrypted |
Enforced | Data is encrypted | Operation fails | Data is encrypted | Operation fails |
Table: Media server DTE mode is Off
Global DTE mode | DTE mode of NetBackup client 9.1 or later | NetBackup host (media server or client) earlier than 9.1 | ||
---|---|---|---|---|
On | Off | Automatic | ||
Preferred Off | Operation fails | Data is not encrypted | Data is not encrypted | Data is not encrypted |
Preferred On | Operation fails | Data is not encrypted | Data is not encrypted | Data is not encrypted |
Enforced | Operation fails | Operation fails | Operation fails | Operation fails |
Table: Mixed media servers (9.1 and 10.0 or later) - Media1: DTE mode On, Media2: DTE mode Off
Global DTE mode | DTE mode of NetBackup client 9.1 or later | NetBackup host (media server or client) earlier than 9.1 | ||
---|---|---|---|---|
On | Off | Automatic | ||
Preferred Off | Media1 - Data is encrypted Media2 - Operation fails Job state - Partial Success Job DTE mode - On | Media1- Data is not encrypted Media2 - Data is not encrypted | Media1- Data is not encrypted Media2 - Data is not encrypted | Media1- Data is not encrypted Media2 - Data is not encrypted |
Preferred On | Media1- Data is encrypted Media2- Operation fails Job state - Partial Success Job DTE mode - On | Media1- Data is not encrypted Media2 - Data is not encrypted | Media1 - Data is encrypted Media2 - Data is not encrypted Job DTE mode - Off | Media1- Data is not encrypted Media2 - Data is not encrypted |
Enforced | Media1 - Data is encrypted Media2 - Operation fails Job state - Partial Success Job DTE mode - On | Media1 - Operation fails Media2 - Operation fails Job state - Fail | Media1 - Data is encrypted Media2 - Operation fails Job state - Partial Success Job DTE mode - On | Media1 - Operation fails Media2 - Operation fails Job state - Operation fails |
If the image DTE mode is On, the default behavior is to restore with data-in-transit encryption for 9.1 and later hosts and to fail the job if any DTE unsupported host involves in the workflow . However, you can still restore by ignoring the image DTE mode.
Use the DTE_IGNORE_IMAGE_MODE configuration option that is to be set on the primary server. Possible values: NEVER (default) | ALWAYS | WHERE_UNSUPPORTED
Table: When the image DTE mode is On and the media server DTE mode is On
Global DTE mode | Host | Value of the DTE_IGNORE_IMAGE_MODE configuration option | ||
---|---|---|---|---|
NEVER (default) | WHERE_UNSUPPORTED | ALWAYS | ||
Preferred Off | NetBackup client 9.1 or later with DTE mode ON | Data is encrypted | Data is encrypted | Data is encrypted |
NetBackup client 9.1 or later with DTE mode OFF | Operation fails | Operation fails | Data is not encrypted | |
NetBackup client 9.1 or later with DTE mode AUTOMATIC | Data is encrypted | Data is encrypted | Data is not encrypted | |
NetBackup host earlier than 9.1 (either media server or client) | Operation fails | Data is not encrypted | Data is not encrypted | |
Preferred On | NetBackup client 9.1 or later with DTE mode ON | Data is encrypted | Data is encrypted | Data is encrypted |
NetBackup client 9.1 or later with DTE mode OFF | Operation fails | Operation fails | Data is not encrypted | |
NetBackup client 9.1 or later with DTE mode AUTOMATIC | Data is encrypted | Data is encrypted | Data is encrypted | |
NetBackup host earlier than 9.1 (either media server or client) | Operation fails | Data is not encrypted | Data is not encrypted | |
Enforced | NetBackup client 9.1 or later with DTE mode ON | Data is encrypted | Data is encrypted | Data is encrypted |
NetBackup client 9.1 or later with DTE mode OFF | Operation fails | Operation fails | Operation fails | |
NetBackup client 9.1 or later with DTE mode AUTOMATIC | Data is encrypted | Data is encrypted | Data is encrypted | |
NetBackup host earlier than 9.1 (either media server or client) | Operation fails | Operation fails | Operation fails |
Table: When the image DTE mode is On and the DTE setting on 10.0 and later media server is Off
Global DTE mode | Host | Value of the DTE_IGNORE_IMAGE_MODE configuration option | ||
---|---|---|---|---|
NEVER (default) | WHERE_UNSUPPORTED | ALWAYS | ||
Preferred Off | NetBackup Client 9.1 or later with DTE mode ON | Operation fails | Operation fails | Operation fails |
NetBackup Client 9.1 or later with DTE mode OFF | Operation fails | Operation fails | Data is not encrypted | |
NetBackup Client 9.1 or later with DTE mode AUTOMATIC | Operation fails | Operation fails | Data is not encrypted | |
NetBackup host earlier than 9.1 (either media server or client) | Operation fails | Data is not encrypted | Data is not encrypted | |
Preferred On | NetBackup Client 9.1 or later with DTE mode ON | Operation fails | Operation fails | Operation fails |
NetBackup Client 9.1 or later with DTE mode OFF | Operation fails | Operation fails | Data is not encrypted | |
NetBackup Client 9.1 or later with DTE mode AUTOMATIC | Operation fails | Operation fails | Data is not encrypted | |
NetBackup host earlier than 9.1 (either media server or client) | Operation fails | Data is not encrypted | Data is not encrypted | |
Enforced | NetBackup Client 9.1 or later with DTE mode ON | Operation fails | Operation fails | Operation fails |
NetBackup Client 9.1 or later with DTE mode OFF | Operation fails | Operation fails | Operation fails | |
NetBackup Client 9.1 or later with DTE mode AUTOMATIC | Operation fails | Operation fails | Operation fails | |
NetBackup host earlier than 9.1 (either media server or client) | Operation fails | Operation fails | Operation fails |
Note:
If the DTE_IGNORE_IMAGE_MODE is set to ALWAYS, the DTE decision is as per the table - Table: Media server DTE mode is Off.
