To The List,
I am looking for what I consider to be a pretty complex solution to
network outages where our mail servers are kept. I have two separate
servers each at their own data center where one functions as the primary
mail server and the other functions as a secondary mx backup.
What I would like to accomplish would be to have short TTL times on
specific A names in DNS, namely the names that are used be end users to
POP in and check their mail. If the primary server were to go down I
could simply change the A names in DNS on that secondary server and have
everyone only experience minor downtime, ~30 minutes. This would
obviously require mirrored vpopmail user accounts on that secondary mail
server, as well as updating of the mirror on a regular basis.
I guess my question is: What files need to be backed up in
QMail/Vpopmail in order for this implementation to work? I would like
to backup just the data that will allow users to login to their
accounts, actual e-mails do not need to be backed up...I must also state
that both vpopmail installations will be running a MySQL backend which
will need to be updated as well...I already have a script for the MySQL
part, I am just wondering which files need to be backed up as well.....
Any suggestions or comments are appreciated. I also wanted to thank
Bill for his time and energy on the best toaster out their!
