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.
Thanks, Greetings and nice Day
