Full Server Backup and Restore of “open source version”

[czaveri]

Thanks Kevin,

(I now feel guilty when anyone from Zimbra replies on this thread)

Thank-you very much for Zimbra.

[bobby]

hey also if you put the account in maintenance mode you can't access via imap(sync)

ok just an update-

how i've been doing my backups for the past month:

stop zimbra

sleep 1m

flush

grep ps for zimbra, and kill them if they haven't stopped yet

grab a LVM readonly snapshot of the /opt/zimbra directory

start zimbra

tar and scp zimbra based on the new snapshot

delete the snapshot


I'll put a script up once i clean things up a bit...

I'll be interested in that, i've already got a few different types of backups going on, but i'm not convinced by the reliability of some of the methods...

I thought you may be interested in a few modifications I made to the LVM backup script posted earlier in the thread.

#!/bin/bash

time=`date +%Y-%m-%d_%H-%M-%S`

# Modify the following variables according to your installation
#########################################

# backup_dir - directory to backup to
backup_dir=/tmp/backups/$time

# vol_group - the Volume Group that contains $zimbra_vol
vol_group=LVM

# zimbra_vol - the Logical Volume that contains /opt/zimbra
zimbra_vol=opt

# Do not change anything beyond this point
#########################################

# Test for an interactive shell
if [[ $- != *i* ]]
   then say() { echo -e "$*"; }
     # Colors, yo!
     GREEN="\e[1;32m"
     RED="\e[1;31m"
     CYAN="\e[1;36m"
     PURPLE="\e[1;35m"
   else say() { true; } # Do nothing
fi

# Output date
say $GREEN"Backup started at "$RED`date`$GREEN"."

# Stop the Zimbra services
say $CYAN"Stopping the Zimbra services..."
say $PURPLE"  This may take several minutes."
/etc/init.d/zimbra stop

# Create a logical volume called ZimbraBackup
say $GREEN"Creating a LV called ZimbraBackup:"$PURPLE
/usr/sbin/lvcreate -L1000M -s -n ZimbraBackup /dev/$vol_group/$zimbra_vol

# Create a mountpoint to mount the logical volume to
say $GREEN"Creating a mountpoint for the LV..."
mkdir -p /tmp/ZimbraBackup

# Mount the logical volume to the mountpoint
say $GREEN"Mounting the LV..."
mount /dev/$vol_group/ZimbraBackup /tmp/ZimbraBackup/

# Start the Zimbra services
say $CYAN"Starting the Zimbra services..."
/etc/init.d/zimbra start &

# For testing only
#say $RED"Press Enter to continue...\e[0m"
#read input

# Create the current backup
say $GREEN"Creating the backup directory..."
mkdir -p $backup_dir
tar zcvf $backup_dir/zimbra.backup.tar.gz /tmp/ZimbraBackup/zimbra/ 2&> /dev/null

# Unmount /tmp/ZimbraBackup and remove the logical volume
say $GREEN"Unmounting and removing the LV."$PURPLE
umount /tmp/ZimbraBackup/
/usr/sbin/lvremove --force /dev/$vol_group/ZimbraBackup

# Done!
say $GREEN"Zimbra backed up to "$CYAN$backup_dir$GREEN"!"
say $GREEN"Backup ended at "$RED`date`$GREEN".\e[0m"

Let me know if you have any feedback.

Dana,
What a wonderful script.
Would you mind editing the wiki and posting in there for others?

Thanks

What modifications should I do to do this without LVM
The System has LVM but not in the /opt/zimbra, it is in the root directory /
how can I use this script just making the backup to nomal directories??

[robbyt]

hey dana, i found that doing a zimbra service stop doesn't always get everything closed down nice and clean, so i throw this after the service stop command in my script:

sleep 30
kill -9 `ps -U zimbra|grep [0-9]|awk '{print $1}'` > /dev/null

here is a copy of my old coldbackup script, pre lvm...
just a warning! it's a bit ugly
This script will scp the backup file off to another computer for safe storage. YMMV!

#!/bin/bash
DATE=`date +%b%d`
ZMDATA=/opt/zimbra
BACKUPFILE=/opt/zimbra-$DATE.tar.gz
DEST=zimbrabak@srvfile01:/home/archive/zimbra/backup.tar.gz
LOG=/root/zimbra/backup.log


echo "started at `date`" >  $LOG
echo "___________________________________" >> $LOG


/etc/init.d/zimbra stop
sleep 30
sudo -u zimbra /opt/zimbra/bin/zmcontrol stop
sleep 30

echo "" >> $LOG
echo "process list after first zimbra stop:" >> $LOG
ps -U zimbra >> $LOG

#lets clean up any left-overs...
kill -9 `ps -U zimbra|grep [0-9]|awk '{print $1}'` > /dev/null
sleep 10


echo "" >> $LOG
echo "process list after kill `date`:" >> $LOG
ps -U zimbra >> $LOG


cd /opt
tar -czf $BACKUPFILE $ZMDATA


/etc/init.d/zimbra start &

#now let's xfer this to $DEST
scp -i /root/.ssh/zimbrabak $BACKUPFILE $DEST
rm -rf $BACKUPFILE &

you can ignore all of the logging stuff- i was having issues with some of the services not closing down all the way so i threw some basic logging in.

I don't know if this would be considered a bug in the backup script on the wiki or just a "watch out".

But, my /opt/zimbra directory is the logical volume. Not a subdirectory.

Filesystem           1K-blocks      Used Available Use% Mounted on
/dev/hda2              6940516   3188004   3394264  49% /
/dev/hda1               101086      9363     86504  10% /boot
/dev/shm                119784         0    119784   0% /dev/shm
/dev/mapper/mail-pmail
                       5039616    739268   4044348  16% /opt/zimbra
/dev/shm                153600         0    153600   0% /opt/zimbra/amavisd-new-2.3.3/tmp

So, line 62 of the script (the tar line) which originally looks like this:

tar zcvf $backup_dir/zimbra.backup.tar.gz /tmp/ZimbraBackup/zimbra/ 2&> /dev/null

Should probably look more like this:

tar zcvf $backup_dir/zimbra.backup.tar.gz /tmp/ZimbraBackup/ 2&> /dev/null

Unless I have my volumes set up incorrectly. But, I really don't want to make my lv /opt. I may place other things in there that I don't want taking up space on the zimbra volume.
