ZDB to tape

(ZDB specific term) A form of zero downtime backup where

 

data in the replica produced is streamed to a backup medium,

 

typically tape. Instant recovery is not possible from such a

 

backup, so the replica need not be retained on the disk array

 

after backup completion. The backed-up data can be restored

 

using standard Data Protector restore from tape. On split mirror

 

arrays, split mirror restore can also be used.

 

See also zero downtime backup (ZDB), ZDB to disk, instant

 

recovery, ZDB to disk+tape, and replica.

zero downtime

A backup approach in which data replication techniques,

backup (ZDB)

provided by a disk array, are used to minimize the impact of

 

backup operations on an application system. A replica of the

 

data to be backed up is created first. All subsequent backup

 

operations are performed on the replicated data rather than the

 

original data, while the application system can be returned to

 

normal operation.

recovery.
