change global inbox location + do auto backup

How can I change the default location of the global inbox location?

And is there any way to to automatically do a daily backup archive?

Thanks.

One approach is to search the forum for prior postings on relocate global inbox.

Again, search the forum … there are lots of approaches taken for this that have been described frequently. Do you use Time Machine? Check the Help file and the guidance provided at Preferences > Backup.
