Резервное копирование и восстановление (Backup and recovery) Zimbra CS OSE

Пример организации холодного резервного копирования и восстановления из архива.
Можно повесить на крон и прикрутить отправку лога по мэйлу. Минусы: сервер приходится останавливать, хотя время останова минимизировано и в основном уходит на останов - подъем, но это минус.
1) Запись в кроне:

2) Текст скрипта:
#!/bin/bash

# Zimbra Backup Script
# This script is intended to run from the crontab as root

# Outputs the time the backup started, for log/tracking purposes
echo Time backup started = $(date +%T)
before="$(date +%s)"

# Live sync before stopping Zimbra to minimize sync time with the services down
# Comment out the following line if you want to try single cold-sync only
echo "Syncronize beafore backup ..."
rsync -aHK --delete /opt/zimbra/ /opt/backup/zimbra

# which is the same as: /opt/zimbra /opt/backup
# Including --delete option gets rid of files in the dest folder that don't exist at the src
# this prevents logfile/extraneous bloat from building up overtime.

# Now we need to shut down Zimbra to rsync any files that were/are locked
# whilst backing up when the server was up and running.
before2="$(date +%s)"

# Stop Zimbra Services
echo Time befor stop Zimbra services = $(date +%T)
echo "Stop zimbra services ..."
/etc/init.d/zimbra stop
sleep 20

# Kill any orphaned Zimbra processes
echo "Kill any zimbra processes ..."
ORPHANED=`ps -u zimbra -o "pid="` && kill -9 $ORPHANED
echo Time after stop Zimbra services = $(date +%T)

# Sync to backup directory
echo "Syncronize to backup directory ..."
rsync -aHK --delete /opt/zimbra/ /opt/backup/zimbra

# Restart Zimbra Services
echo Time befor start Zimbra services = $(date +%T)
echo "Start zimbra services ..."
/etc/init.d/zimbra start
echo Time after start Zimbra services = $(date +%T)

# Calculates and outputs amount of time the server was down for
after="$(date +%s)"
elapsed="$(expr $after - $before2)"
hours=$(($elapsed / 3600))
elapsed=$(($elapsed - $hours * 3600))
minutes=$(($elapsed / 60))
seconds=$(($elapsed - $minutes * 60))
echo Server was down for: "$hours hours $minutes minutes $seconds seconds"

# Create a txt file in the backup directory that'll contains the current Zimbra
# server version. Handy for knowing what version of Zimbra a backup can be restored to.
su - zimbra -c "zmcontrol -v > /opt/backup/zimbra/conf/zimbra_version.txt"
# or examine your /opt/zimbra/.install_history

# Display Zimbra services status
echo Displaying Zimbra services status...
su - zimbra -c "/opt/zimbra/bin/zmcontrol status"

# Create archive of backed-up directory for offsite transfer
echo "Create archive of backed-up directory for offsite transfer..."
rm /opt/zimbra.tar.gz
tar -zcf /opt/zimbra.tar.gz -C /opt/backup/zimbra .

# Transfer file to backup server
cd /opt
curl -T /opt/zimbra.tar.gz ftp://ftpserver

# Outputs the time the backup finished
echo Time backup finished = $(date +%T)

# Calculates and outputs total time taken
after="$(date +%s)"
elapsed="$(expr $after - $before)"
hours=$(($elapsed / 3600))
elapsed=$(($elapsed - $hours * 3600))
minutes=$(($elapsed / 60))
seconds=$(($elapsed - $minutes * 60))
echo Time taken: "$hours hours $minutes minutes $seconds seconds"
3) Скрипт для восстановления (но лучше делать все ручками):
#!/bin/bash

# Stop Zimbra Services
echo "Stop zimbra services ..."
/etc/init.d/zimbra stop

# Kill any orphaned Zimbra processes
echo "Kill any zimbra processes ..."
ORPHANED=`ps -u zimbra -o "pid="` && kill -9 $ORPHANED

# Move /opt/zimbra to new location i.e. /tmp/zimbra-old
mv /opt/zimbra /opt/zimbra.old

# Uncompress the most recent backup file to the /opt/zimbra foldertar zxvf [backup file] -C /opt/zimbra
mkdir /opt/zimbra
tar zxvf zimbra.tar.gz -C /opt/zimbra

# Fix the Zimbra permissions
chown -R zimbra:zimbra /opt/zimbra
/opt/zimbra/libexec/zmfixperms

# Start all Zimbra services
/etc/init.d/zimbra start

# Check Zimbra services status
su - zimbra -c "/opt/zimbra/bin/zmcontrol status"
