Proxmox VE虚拟机备份脚本
掐指一算发现自己组的软路由已经服役近3年，虽然目前为止都在稳定运行，但是担心哪天这个基于Proxmox VE的"All in boom"设备凉了就得从头配一遍，就写了个小脚本每天备份PVE上的虚拟机，并同时在本地和云端存一份备份。
备份脚本
脚本本体
#!/bin/bash
export PATH="/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin"
jobstatus=$1
vmid=$3
vmtype=${VMTYPE} # openvz/qemu
dumpdir=${DUMPDIR}
storeid=${STOREID}
vmname=${HOSTNAME}
tarfile=${TARFILE}
logfile=${LOGFILE}
echo "Job Status: $jobstatus"
if [ "$jobstatus" == "post-restart" ];then
printf "HOOK-ENV: vmid=$vmid;vmtype=$vmtype;dumpdir=$dumpdir;storeid=$storeid;hostname=$vmname;tarfile=$tarfile;logfile=$logfile\n"
fi
if [ "$jobstatus" == "backup-end" ]; then
exec > >(tee -ia $logfile)
exec 2> >(tee -ia $logfile >& 2)
exec 19> $logfile
while :
do
let LOOPS+=0
echo "Retry times: $LOOPS"
if [[ $LOOPS -gt 5 ]]; then #Set retry count
break
fi
echo "Uploading VM ${vmid}-${vmname} to cloud storage..."
# Add your upload code here if you want to upload backup files to any cloud storage
exit 0;
done
fi

我的备份方案
使用本文中的PVE备份脚本产生本地备份，然后传到本地NAS，本地NAS上配置了自动上传到B2云备份。
