Hello,
I'm taking backups of Oracle Databases with rman and Networker, and the
deduplication ratio does not exceed 4x.
This is my rman configuration:
CONFIGURE DEFAULT DEVICE TYPE TO sbt;
run
{
allocate channel t2 type 'SBT_TAPE' format 'b_%u_%p_%c';
SEND DEVICE TYPE 'SBT_TAPE'
'NSR_ENV=(NSR_SERVER=hostname,NSR_CLIENT=hostname,NSR_DATA_VOLUME_POOL="Default",NSR_NO_MULTIPLEX=TRUE,NSR_SAVESET_RETENTION=5
days)';
BACKUP filesperset 1 DATABASE;
}
EOF
The backup of the file systems of the same clients with Networker has an
average of 30x.
Any advice will be of great help.
Thank you!
