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 Michelle Konzack Systemadministrator 24V Electronic Engineer Tamay Dogan Network Debian GNU/Linux Consultant -- Linux-User #280138 with the Linux Counter, http://counter.li.org/ ##################### Debian GNU/Linux Consultant ##################### Michelle Konzack Apt. 917 ICQ #328449886 +49/177/9351947 50, rue de Soultz MSN LinuxMichi +33/6/61925193 67100 Strasbourg/France IRC #Debian (irc.icq.com)
