I’m wanting to make sure I have everything I need backed up correctly. On some level, the only real thing I care about is the email itself, and since its in Maildir format - I can restore it to almost any system if need be in the future.
My crons work like this.
- Every 5 minutes, sync vmail offsite.
- Every 5 minutes, sync vmail-index offsite.
- On Sundays, do a full backup of all components.
- On the other 6 days, do a backup of all components except vmail.
5 Every day, send backups offsite.
Any thoughts, feedback, or pitfalls I’m not thinking about?
