before installation

there are no defaults that fit your needs - irm is simple to implement
but you have to decide what you need BEFORE you start an productive environment!
using irm and iRedOS is simple and easy - but there are some points you want to read before you present a "finished server" to a customer...

before installation of your OS

• align your disk-partitions before creating filesystems
• format your /var/vmail partition using ext4

after installation of your prefered OS

• Keep your computer-time in sync

before installing irm

before creating user-accounts

• enable zlib plugin for dovecot's transfer
• enable zlib plugin for dovecot's 2.x storage

backups

config-files

whenever you can :)
keep a copy of /etc

slapcat your openldap

mkdir /root/ldap_backup

edit your crontab and add

8   */1   *   *   *   /usr/sbin/slapcat -f /etc/ldap/slapd.conf >  /root/ldap_backup/slapcat_dump &> /dev/null

or maybe you want to take a look at IRedMail/FAQ/Backup

mail-data

we are talking about defaults:
maildir for mail-storage means: rsync might be enough

mysql-data

ldap-data

recovery ... oops

if you really need to read this ... yeah, shi### happens ;)

but you are not alone!
we will provide you some BAD practice and hints on what NOT to do!
if you need to read this - please follow this procedure:

Stop reading, take a cup of coffee and come back in 5 minutes
