Automatic backup XenServer VM by creating snapshot

[xtdv]

You need xe-cli package installed on your Linux machine. It comes with XenServer installation CD, named xe-cli....rpm.

Create a file named xe_snapshot_running.sh:

Mã:

touch ~/xe_snapshot_running.sh

Fill in the file with contents below:

Mã:

# Define variables and paths
DATE=`date +%Y%m%d`
XE_CLI=/usr/bin/xe
XE_ARG=""

# Index arguments
for VARIABLE in "$@"
        do
                ARGUMENT=("${ARGUMENT[@]}" "$VARIABLE")
        done

INDEX=1
for VARIABLE in "$@"
do
        # Find server address variable
        if [[ $VARIABLE == "-s"  ]]; then
                #WARN_TIME="${ARGUMENT[$INDEX]}"
                XE_ARG="$XE_ARG -s ${ARGUMENT[$INDEX]}"
        fi
        # Find server port variable
        if [[ $VARIABLE == "-p"  ]]; then
                #CRIT_TIME="${ARGUMENT[$INDEX]}"
                XE_ARG="$XE_ARG -p ${ARGUMENT[$INDEX]}"
        fi
        # Find login name variable
        if [[ $VARIABLE == "-u"  ]]; then
                #WARN_SIZE="${ARGUMENT[$INDEX]}"
                XE_ARG="$XE_ARG -u ${ARGUMENT[$INDEX]}"
        fi
        # Find password variable
        if [[ $VARIABLE == "-pw"  ]]; then
                #CRIT_SIZE="${ARGUMENT[$INDEX]}"
                XE_ARG="$XE_ARG -pw ${ARGUMENT[$INDEX]}"
        fi
        ((INDEX++))
done

if [[ $XE_ARG == *-s* ]]; then
        # List running VMs and get UUIDs
        VM_UUID_RAW=(`$XE_CLI vm-list power-state=running is-control-domain=false params=uuid $XE_ARG |awk '{print $5}'`);

        # Snapshot all VMs in the list
        for VM_UUID in ${VM_UUID_RAW[@]}; do
                eval $XE_CLI vm-snapshot vm=$VM_UUID new-name-label="AutoBackup $DATE" $XE_ARG
                if [ $? == 0 ]; then
                        echo -e "Virtual Machine has been snapshoted successful.\n"
                else
                        echo -e "Virtual Machine has not been snapshoted.\n"
                fi
        done
else
        echo "Usage: xe_snapshot_running.sh [-s server] [-p port] ([-u username] [-pw password])"
fi

Make it executable and edit your crontab to run it automatically

Mã:

chmod +x ~/xe_snapshot_running.sh
crontab -e

Example crontab running the snapshot weekly:

Mã:

59 23 * * 5 /root/xe_snapshot_running.sh -s xen1.xtdv.local -u root -pw password
