[b] 4.4.4 Improving Incremental Backup Performance: Change Tracking[/b]


[font=Tahoma, sans-serif]Change tracking is disabled by default, because it does introduce some [b]minimal performance overhead on your database during normal operations[/b]. However, the benefits of avoiding full datafile scans during backup are considerable, especially if only a small percentage of data blocks are changed between backups. If your backup strategy involves incremental backups, then you should enable change tracking.[/font]

hmm... idi edo think seyalsina visayam.. kaani performance overhead aite pakka untundi ante expect chesa.. but veedu mari minimal antunnadu ante, maa retail transactions ki adi koddiga ekkuve untadi..

right now, maku 10 TB sizes prod db's unnai.. vati ki backups oka 11.30 hours close to 12 hours tesukuntadi....

okasari test env lo chusi check cheyali
