daniel,
i have learned the hard way that you should be making incremental
backups of all of your machines every night. a decent backup solution
should take care of this.
my advice is "try it!" testing is simple enough: scp /var/db/spamdb to
another machine, run spamdb and see if your IPs are preserved.
Hi Jake,
The only thing about just copying the file-- I don't want to catch the
database in some intermediate state. I understand that spamd uses
Berkeley DB, and I'm guessing that it is able to recover from errors,
but I honestly don't know since I've never used Berkeley DB for anything
myself. For now, I'll take your advice and just scp the file to another
machine.
I do incremental backups for the machines that count. For me, a
firewall is not one of them, since with the exception of the spamdb
file, there is no important information stored on it. I keep system
configuration files for these kinds of machines elsewhere so that we can
quickly put together replacements if they fail. That's good enough for
me, and less work than making sure that a couple dozen incremental
backups are actually running correctly every night.
