Gmail Backup done !
mike | Wednesday, 9. March 2011 0:05After I found out that also Gmail maybe has a need for Backup I found a few Ideas / Software to made a Backup.
First I remember that now Zarafa is in Fedora ! –> Thanks to kanarip http://planet.ergo-project.org/
So that’s easy setup a Fedora 14 on my KVM Hosts and install the Zarafa Community Version of it.

# yum install zarafa zarafa-webaccess mysql-server httpd # service mysqld start # service zarafa-server start # service zarafa-gateway start # service zarafa-spooler start # zarafa-admin -s # zarafa-admin -c USERNAME -e USERNAME@localhost -f “Zarafa Tester” -p PASSWORD # service httpd restart
Then go to http://Server/webaccess –> done
maybe also make them persistent against reboot with “chkconfig Servicename on” per Service.
Then the Problem pops up how to sync my Gmail account with the Zarafa Server. So Imapsync was the first choice, but it turns out that it could be tricky not not so performant

# imapsync –noauthmd5 –allowsizemismatch –syncinternaldates –host1 imap.gmail.com –ssl1 –port1 993 –user1 YYYYYYYYYY@gmail.com –password1 XXXXXXX -sep2 / –prefix2 “” –host2 192.168.1.245 –user2 YYYYYYY –password2 ZZZZZ –folder “[Gmail]/All Mail” –regextrans2 ‘s/\[Gmail\]/Gmail/’ —useheader ‘Message-Id’ —skipsize –dry
Also the Server need lot of Memory, first I think 512 MB is enough, Wrong I go to 1GB / 2CPU now its better ( see graph, red is swap before go to 1GB). Also the process toke very long and skip lot of mails.
so I search another Methode and found it with OfflineIMAP
“Be aware that this is a Offline Version and will be synced back to Gmail if you delete or change something in the Offline Version next Time you sync !!!!!”

#sudo apt-get install offlineimap
and just add ~/.offlineimaprc to your homedrive
