1

question 1:

i read documention of xtrabackup ,i found :

innobackupex --apply-log --redo-only BASE-DIR --incremental-dir=INCREMENTAL-DIR-1

Repeat the procedure with the second one:

innobackupex --apply-log BASE-DIR --incremental-dir=INCREMENTAL-DIR-2

why the second step not have --redo-only option ?

question 2:

my database has five database, and i want to backup two of this five ,what should i do ? use incremental backup and partial backup ? is the order of restoring the backup :prepare incremental backup then the partial backup ?

Thanks！

Question 1 is answered in the manual. I am not sure whether Question 2 is answered in the manual. I would need to spend some time researching this to provide a good answer. Unfortunately I’m too busy to do that soon :frowning:
