Hello *, the FileServer im my Enterprise hosts arround 60 users and has apache, courier-imap, php5, ssh and proftpd installed. For arround 3-2 years I was running into trouble with the huge Maildirs in the ${HOME}/Maildir and have put them onto a separated Disk-Array and symlinked the ~/Maildir into the users HOME. Curently I have: /dev/sda1 1G / rescue /dev/sda2 2G swap /dev/sda3 20G /tmp /dev/sda5 2G / production 1 /dev/sda6 1G /var/log production 1 /dev/sda7 2G / production 2 /dev/sda8 1G /var/log production 2 /dev/sda9 20G /PostgreSQL postgresql 8.1 /dev/sdb1 150G /Maildirs holding 60 Maildirs /dev/sdc1 300G /home where I have two RAID-1 FOR "sda" (2 x WD740GD) and "sdb" (2 x WD1500GD) and for "sdc" a Raid-5 (4 x WD1500GD) located on two 3Ware 3W9500S-4. Now I backup each night and for the /home it is no problem since the most files are big and each ${USER} backup has only 2-3 GByte except my ${HOME} which is very huge (26 GByte). My problem is the /Maildirs directory!!!!!!!!!!!!!!!! -- Argh! It taks to much time (over 5 hours) to do incremental backup using the rsync method. Can anyone tell me a PERFECT solution to backup 60 Maildirs (maybe increasing) which hold per $USER over 1 million files? Since the Server is nearly 95 sleeping, I use only a Semrpon 2200+ with 2 GByte of memory. But since Socket A CPU's do not more exist, I do not realy like to change the Mainboard, CPU, Memory + Graphiccard only to get (my current) Backup done in less then 30 Minutes. Can anyone recomment a Maildir specialized backup method/program? I like to get Backups per ${USER} and in tar.bz2 format which mean, per backup and ${USER} each time two archives. Also the backup solution should create ONE full-backup and SIX incremental-backups plus transfer using scp to another host.
