Re: performance of backup degrade continuously

I'm sorry that I did not explain my situation clearly.

The amount of data to be backed up is increasing SLOWLY, because we only keep data for around 6 month ( one table for each month). Although the number of record increase time, the size of data to back up differs not so much. while the time for backup operation increase much faster than expected.
