Last updated on OCTOBER 31, 2016
Applies to:Oracle Database - Enterprise Edition - Version 10.2.0.4 to 22.214.171.124 [Release 10.2 to 11.1]
Information in this document applies to any platform.
RMAN restore from sbt backup is very slow compared to backup speed.
Backup rate is 60-90 Mb/sec.
Restore rate is 6 Mb/sec.
Backup is hardware multiplexed but media manager does support multiplexed backups.
Restore validate runtime is VERY fast so problem is the write back to disk.
