Filed under: RMAN — yasinsaygili @ 9:26 pm

Before Oracle 10g ,oracle has incremental backup,but today oracle made incremental updated backup

oracle wants create image copies on datafile so oracle produced that

,this is a RMAN solution,it is amazing options for big warehouse

because

  1. the most important thing ,time ,you saved time with incremental updated backup.
  2. another important situation ,Incremental update backup is not need high storage capacity than last version(incremental backup)
  3. This another important performance with incremental updated backup.

if we research about incremental updated backup,

lets we make basic sample with  incrementally updated backup

run

{ recover copy of database with tag ‘a’;

backup

incremental  level 1  tag ‘a’

for recover of copy with tag ‘a’

database;

}

p.s. “a” is tag for backup ,it is whichever a value for backup
