Hmm...Jon's question got me to a'thnkin' about something that I haven't yet read about.
So let's say the dump cycle is 30 days and I want to keep a copy of the previous month's dump before the tape1 gets overwritten so that I can keep a record of the state of the database from two months ago. If I understand the terminology, this would be an archive? So a strategy might be: on the 30th day, do a full dump, and copy it to 'somewhere safe', whether on S3, or a DVD. That seems like a pretty straight-forward concept, but might this idea be improved upon somehow? I just finished reading O'Reilly's Backup and Restore (a very disappointing book) that only brushed over some strategies, and Google seems to show me only the same few pages on how to setup a config with only a topical discussion about scheduling. Anyway, thanks for your responses and ideas! -- Andrius On Sat, Jan 11, 2014 at 12:05 PM, Andrius D.
