how can I create incremental backups with xtrabackup automatically

Question

It says on the manual that if you want to create an incremental backup you can do it with the following command:

xtrabackup --backup --target-dir=/data/backups/inc1 \
--incremental-basedir=/data/backups/base --datadir=/var/lib/mysql/

where /data/backups/inc1 is the incremental directory. So now if I want to create a cronjob (which I don't think I'm the only one), I have to figure out a way to name my directory every time I want to create a new incremental backup, which could be tedious.

Is there any way to maje xtrabackup to create directories using timestamps instead?

您可以使用内置的Linux命令date根据需要命名目录，例如

xtrabackup --backup --target-dir=/data/backups/inc`date +%Y%m%d` (rest options)
