Hello,
On my "business" mailserver (courier-imap) I have 43 users (some of them
as On-Line-Archive), together over 42.000 mailfolders and 17.000.000
messages stored and each month we get 1800 mailfolders and 150.000
messages more. The total volume is arround 180 GByte. (real not blocks)
Currently I run a daily plus weekly cronjob with a selfmade script which
check first the /cur/ directories and if it does not match a previously
created MD5 + directory listing it will backuped. Daily incremental and
weekly full.
The daily incremental backup take arround 5 hours and the weekly full
backup arround 8 hours.
OK, the BaSH script works very fast but there is a problem with it...
It take 100% CPU resources... and it is nearly impossibel to connect
via IMAP to the server since the connection times out... :-(
Q1: Is there someone with a similar problem and can help out?
Q2: Would it be better, if I install 2-3 very small additional storage
servers (they need only 147 GByte Raid-1 storage each) which hold
only the huge Mailarchives and serv them over a separated GigaBit)
link? (I can install a second NIC in the imap server connect
to a 5 port Switch for the backup server and storage servers)
Note: The backup server is an Athlon XP1800+/512GB with Adaptec 29160
and has 6 x 74 GByte of storage for 6 weeks. (one HDD per week)
Thanks, Greetings and nice Day
